Diseases of roses turn yellow and leaves fall off. Why do rose leaves dry out? Treatment and prevention of diseases

For what reasons do rose leaves dry out?

Caring for a rose is not as easy as it might seem at first glance. The plant can sense any change in cultivation and respond with the same dried leaves. But there could be a lot of reasons. Therefore, before solving the problem, you immediately need to determine why the leaves of the rose are drying, what influenced it.

Causes:

• improper watering, lack of moisture or excess;

• unfavorable landing site;
• lack of necessary microelements and substances;
• various viral and fungal diseases;
• presence of pests.

Current questions about yellowing of rose leaves

Question No. 1. How to deal with yellowing leaves of roses in a greenhouse?

The reasons for yellowing of roses in greenhouses and conservatories are the same as for outdoor plants. A control plan must be developed by first finding out why this condition arose. Sometimes in greenhouses yellow spots on roses can appear due to sunburn. In this case, it is necessary to take care of shading - for example, using a special mesh.

Question No. 2. Are the treatments for yellowing leaves different in different types of roses?

No, they are not different. The fight against yellowing depends on its cause, and not on the type of rose.

Question No. 3. What to do if your indoor rose turns yellow?

First, establish the cause. Indoor roses most often turn yellow due to lack of light or nutrition. It is better to keep them on racks equipped with phytolamps, since the illumination of window sills is usually insufficient, especially in autumn and winter. The duration of daylight should be at least 16 hours.

It is also important to regulate watering. The need for watering is determined by soil moisture at a depth of 2 cm. This can be easily done using a wooden skewer. If it remains dry and clean after immersion in the ground, the rose needs to be watered.

Question No. 4. Is there any point in leaving yellowed leaves on a rose?

Yellowing of leaves is an irreversible process. It occurs due to the destruction of chlorophyll. At the same time, metabolites accumulate in the leaf tissues, which lead to its death. Once a leaf turns yellow, it will no longer turn green, so there is no point in leaving it on the bush. And if the yellowing was caused by a disease, it can even be dangerous - the infection will spread further throughout the plant. Based on this, yellow leaves from the bush need to be removed.

Question No. 5. Can a rose turn yellow due to a sudden change in weather from warm to cold?

Modern varieties and hybrids of roses usually show high resistance to unfavorable climatic factors. However, a sharp cold snap can indeed cause yellowing of the leaves. Therefore, in extreme summers with unstable weather, it is advisable to keep non-woven covering material on hand. If the weather forecast promises sharp temperature fluctuations, you can wrap the bushes in it for a while.

Almost all rose lovers who grow them observe yellowing of the leaves of the crop. Moreover, this phenomenon can be observed regardless of the quality of plant care. So why do rose leaves turn yellow? In addition to natural age-related changes in the body of a flower, there are also unnatural groups of causes of yellowing of leaves. What factors cause this phenomenon and how to deal with it?

Watching a rose's leaves turn yellow and fall off is very painful. It is much more pleasant to observe healthy individuals. What are the causes of yellowing leaves? Are straw organs always evidence of illness? In fact, there are many reasons for leaves turning yellow.

Sometimes a leaf turns yellow due to the physiological characteristics of an individual of a certain species and variety. In this case, you should not take any action, especially since it is unlikely that you will be able to change anything. The situation is completely different if the organs of a young bush change color. In this case, inaction can even provoke the death of the plant.

The causes of yellowing of the organs of young individuals can be grouped according to the nature of the manifestation:

• Rapid yellowing and falling off. This phenomenon is usually observed in the case of unfavorable external conditions. In particular, sudden temperature fluctuations. Similar phenomena can be observed in the summer in case of frequent weather changes. However, most modern varieties are adapted to unstable environmental conditions.
• The leaves of roses at the bottom of the bush turn yellow, most likely due to a lack of light. Perhaps the individual grows in the shade and suffers from this.

Therefore, you need to be especially careful when choosing a site for planting roses. This should be a place protected from the wind, well lit by the sun. For example, the south or south-east side of the site is perfect.

In the shade, not only a change in the color of plant organs is observed, but also the elongation of shoots and a slowdown or cessation of flowering.

• Are the leaves turning yellow and curling, and the tips of the organs turning brown and drying out? Rose is trying to tell you that she doesn't have enough water. In addition, under conditions of moisture deficiency, plants become deformed and flowers fall off. The flowering process stops. In hot conditions, representatives of climbing varieties growing near the wall of the building especially feel the lack of water.

Young, recently planted individuals also need systematic moisture.

• Yellow spots appeared on the organs. Usually this phenomenon is caused by a lack of nutrients in the rose body.

Lack of lighting or moisture

Do not forget that roses love light and warmth. Planting it in dark, cool places leads not only to spoiled leaves, but also to withering of the bush, and sometimes to its death. Plant the plant in sunlit areas where there are no drafts. But the rays should not hit the flower all day. It is best when the sun is warm in the first half of the day, and in the evening the rose is slightly cool.

The rose also loves moderate moisture. It should not be watered too often, but regularly. Make sure that there is no stagnation of water in the soil. It is imperative to ensure moisture removal. Using these rules will help you in the future not to rack your brains over why the rose is drying up.

Battery deficiency

Why do the leaves turn yellow? Very often the cause of the phenomenon lies in an imbalance in the supply of fertilizers to plants. Some rose lovers do not pay any attention to the change in the color of the organs and continue to care for the individuals as usual.

• Nitrogen. Often the cause of leaf color change is nitrogen starvation of the crop. For example, a bush planted on poor soil or insufficiently fertilized throughout its life often suffers from a deficiency of the element. If enough nitrogen was added in the spring, the rose bloomed and gained strength, but in this case the plant used all the nitrogen. Without re-fertilizing at the end of summer, you may experience “October” yellowing and leaf drop.

It is not difficult to determine the lack of nitrogen, since the color change occurs gradually, starting with the organs located below. You may not immediately notice the change in color of several leaves. However, after some time the bush will turn almost half yellow, after which the plant turns pale.

Another “spring” sign of nitrogen deficiency is yellowing of shoots. Instead of being dark in color, the organs become pale red or slightly brown. The leaves growing on such stems also have the same color.

It is easy to determine the lack of nitrogen in the crop body, as well as to completely eliminate it. You just need to dilute urea (a tablespoon per 10 liters of water) and pour half a bucket onto the bush. Watering by leaves is allowed. The first positive results will become noticeable after a couple of days, and after 10 days the individual will completely acquire its usual healthy appearance.

• Potassium. When it is deficient, the edge of the leaf first becomes straw-colored, after which the organ changes color to brown and dries out. In this case, ash and potash fertilizers will come to the rescue.
• Iron and manganese. If there is a deficiency of at least one of the elements, the leaves develop chlorosis, and the space between the veins changes color. The vein does not change color, remaining green.

With a deficiency of iron, first of all, the upper young organs turn yellow, and with a lack of manganese, the old leaves turn yellow.

Often, a lack of these elements is observed on soils with a reaction above 7-7.5, that is, on alkaline soils, which usually contain chalk and dolomite. Individuals may also lack iron and manganese in soils that were oversaturated with lime during the deacidification procedure.

What should I do to correct the situation? You can get rid of chlorosis by spraying flowers with a solution of fertilizing with iron and manganese. It is also necessary to normalize the soil reaction (indicator 5.6 - 7). You can acidify the soil with organic matter, for example, mullein. The procedure involves creating a small hole on one side of the plant where there is access to the root. It is necessary to pour 2.5 liters of mullein solution into such a recess. Thus, part of the root system will have access to the soil, which will bring the number of elements back to normal.

Effect of weather conditions

Sometimes all your care efforts can be ruined by unfavorable weather conditions. The leaves of the rose dry out due to too frequent rains. Indeed, in connection with this, the soil becomes waterlogged, water washes away nutrients and the plant suffers.

Temperature changes can also cause spoiled shoots. For example, after heavy rain, the bright sun does not have as good an effect on the flower as we would like. The sun begins to warm up the drops that remain on the plant, and at the same time the rays burn the leaves.

Too hot weather also leads to deterioration of the plant. It is impossible to somehow influence the weather and change it. But a good way out of this situation would be to plant in a convenient place - where the gardener can have maximum control over external factors from watering to lighting.

The buds of a garden rose are drying: what it looks like

A wilted, dried out, non-viable bud is a condition when a flower bud develops normally and even swells to full size, but its petals do not open. The bud is often soft and slippery to the touch, and the outer petals gradually lose color and turn brown. Eventually the entire bud sticks together and merges into one. It may then remain on the stem or fall off, becoming dry and crispy on the outside. If the outer petals are separated from each other, the inner petals appear normal, but this is misleading, especially if the buds are drying up due to disease.

Another condition is when there are buds, they begin to open, but they look frail. The flower itself is underdeveloped, and even if it opens completely, it will look ugly and dull.

Poor nutrition

Lack or excess of nutrients is often the reason why the leaves on roses in the garden dry out. The plant needs constant feeding. But it must be carried out extremely carefully so as not to further harm the bush.

The main substances that the plant needs

It is worth remembering that yellowed and dried leaves are just the first sign of some lack of care. Neglecting this reaction of the plant can lead to its complete death.

Yellowness of leaves as a result of care errors

Leaves may turn yellow and fall off due to improper care. To avoid problems, it is worth monitoring temperature parameters, lighting, and watering.

Lack of lighting

The plant can hardly tolerate exposure to direct sunlight. At the same time, it feels great in the fresh air. Therefore, in June, the bush should be taken out onto the balcony or into the garden, but shaded a little.

Important! It is enough for the plant to be in a lighted place for 5 hours a day. Yellowing foliage indicates uncomfortable conditions

Wrong soil

The rose needs loose soil that allows moisture and water to pass through well.

It is important to avoid stagnation of liquid near the roots

To plant a plant, mix turf and humus in equal parts. You also need to add a little sand to the composition. A drainage layer should be placed at the bottom of the pot.

Eating disorder

The plant needs periodic fertilization. If a crop is deficient in nitrogen, its leaves turn pale and become covered with yellow streaks. Potassium deficiency also has a negative impact on the bush.

The room temperature is not suitable

When growing a crop, it is important to ensure that the rose pot does not overheat. In summer it should be taken out onto the balcony

In winter, the bush can be at room temperature.

Important! It is necessary to provide the rose with protection from the cold wind. She also does not like sudden temperature fluctuations.

Drafts have a detrimental effect on indoor plants

Rose reacts negatively to drafts, but at the same time needs fresh air. To provide the plant with comfortable conditions, it is permissible to make a paper cylinder and wrap it around the pot.

Diseases and pests

Various diseases and pests can undoubtedly lead to dry leaves on roses in the garden.

The condition of the bush can be affected by the following diseases:

The cause of infection is often a new infected bush, or even untreated garden tools (yes, even when working with plants, tools require sterility!). To avoid diseases, prevention must be carried out. This is a mandatory spring treatment of the plant and the soil around it with special products.

New bushes can be soaked in a fungicide solution to avoid infections and fungi, if any.

Also, rose leaves and young shoots may wither if there are pests.

Pests

• Rose leafhopper. Small insects are yellow. They are often the reason why roses wither without blooming.
• Spider mite. They can be seen on the inside of the leaf in the form of white balls. They also leave small cobwebs in the buds and on the stem.

You can get rid of the above pests using special insecticidal agents.

Remember that before you determine what to do with the plant, you need to understand why the leaves of a garden rose dry out. After all, the wrong help can aggravate an existing problem.

Reason 2. Potassium starvation

A different pattern of yellowing is observed with a lack of potassium. First the leaf plate in

generally retains green color. The edges begin to turn yellow, gradually drying out. This pattern is called a “marginal burn.”

Over time, the leaf turns yellow and dries out completely. Young leaves of roses experiencing potassium starvation may turn red and then turn black. The deficiency of this element can be compensated by applying special fertilizers - potassium magnesium or potassium sulfate. This is done by watering with a solution prepared at the rate of 1 tablespoon per 10 liters of water. To avoid this situation, it is useful to spray roses with potassium humate throughout the growing season. This needs to be done every 2 weeks.

Why does a rose shed its leaves? What to do?

Understanding the reasons, of course, is necessary and important, but it is very important to do this quickly in order to help the bushes in time and restore them by the time they begin to prepare for winter.

What happened to the rose?

Very often, having planted a rose bush, we do not pay attention to the foliage. Buds and flowers are what interests the gardener in the first place. But when the foliage becomes covered with black or brown spots, or the shoot becomes completely bare, we begin to sound the alarm.

Unsightly foliage or its complete absence is not only, and not so much an aesthetic problem (it is impossible to make a beautiful bouquet with such a flower), but a problem that can lead to the death of the rose bush.

The leaves of a rose do not fall off all at once; this process was certainly preceded by some events, these could be:

• black spots on the leaf blade;
• brown spots on foliage;
• felt continuous coating;
• white powdery coating;
• yellowing of foliage starting from the veins.

After some time, the rose sheds its leaves and this is not the norm, but a sign of illness.

Why did the rose get sick?

This question arises especially often when the rose bush has not been growing for the first year and the annual flowering was lush and pleasing to the eye. In this case, it is necessary to analyze the climatic parameters of past years and this year. Upon reflection, it becomes clear that nature “pampered” us and consoled us with its warmth and sun in previous years, but this year it rained and cooled us with wind, as a result of which microscopic pathogenic fungi affected the rose bushes. Or light night precipitation alternated with intense daytime heat, which provided excellent conditions for the growth of fungi.

Promote increased virulence of microorganisms:

• high humidity;
• dampness;
• cold winds;
• cold night dew;
• alternating heat and cold with high humidity.

The mushrooms have begun their active phase. The leaves curled, became covered in spots and gradually fell off.

There are not many fungal diseases that cause leaves to fall, but to help the rose bush, you need to know them by sight.

Why did your rose get sick?

To maintain the immune status, the plant needs mineral elements, which are part of the enzymes and act as an immunostabilizer.

If a rose bush has been growing for a long time, then the soil under it has become depleted. Even if you fertilize with nitrogenous fertilizers in early spring, this gives it the opportunity to forcefully “shoot” fatty shoots, but does not add strength to fight microflora.

If you fertilize with potassium and phosphorus fertilizers before budding, this will give you the opportunity to set buds and bloom, but again will not give you the opportunity to fight the infection.

Without the addition of organic fertilizers, without partially replacing the soil under the bushes, the beneficial microflora of the soil weakens, and the nutrients become inaccessible to the rose bush. The plant lowers immunity, and the virulence of microscopic fungi increases, which leads to the manifestation of the disease.

Black spot of roses

The most common disease. Rose growers joke: “If there is a rose, then there is spotting.” Unfortunately, breeders have not yet been able to develop a rose variety that is resistant to the fungus that causes this disease. There are varieties that are more or less resistant, but there are no completely resistant ones.

Examining the leaf blade from above, we see black spots, which sometimes extend to the shoot. Over time, the leaves turn brown and fall off.

Rust rose

If the shoot is already bare, then to answer the question “Why do roses shed their leaves in the summer?” you need to consider the remaining foliage, or the one that lies under the bush.

On the inside of the leaf blade of the pink leaf you can see small orange, slightly velvety piles - these are mushrooms. After some time, the damage increases, the leaf turns yellow and falls off.

Polyanthus, climbing and hybrid tea roses are more susceptible to rust.

Powdery mildew of roses

Initially, the leaf is covered with white spots, they grow, and now the leaf becomes completely white, as if sprinkled with flour. Photosynthesis stops, the leaf blade curls and falls off.

The shoots are covered with felt, sometimes forming “pads”. Over time, the plaque turns brown. Growth stops and flowering does not occur. In winter, the affected bush may die.

This fungus develops in a humid environment, but at high temperatures.

There are varieties of roses that are not affected by the fungus that causes this disease, for example: “New Down”, “Gloria Den”, “Excelsa”.

What can a gardener do to protect his queen and help her “dodge” an attack - of course, reduce the number of fungal spores.

Yellowing of roses due to lack of nutrients in the soil

Many people ask this question: why do rose leaves turn yellow? Often the reason for this is an insufficient amount of nutrients in the soil:

• Nitrogen deficiency is characterized by faded and wilted leaves.
• When the phosphorus content in the soil is low, not only the above-ground part is affected, but also the rhizome. An excess of this substance is also undesirable.
• Potassium is responsible for the duration and intensity of flowering. Its insufficient quantity manifests itself in the appearance of brown, yellow spots on the leaves.
• Chlorosis is caused by a lack of iron in the soil. Its first signs are yellowing of the leaf.

How to cure roses

The causative agents of all of these diseases are microscopic pathogenic fungi. Their nature is different, the germination conditions are also different, but fungicidal (antifungal) drugs act the same.

All activities must begin in early spring, at the moment when you are just opening the rose bushes. After inspecting the condition of the plant, add rotted compost and manure under it and water everything with biofungicides - preparations containing beneficial soil microflora. Among such drugs are “Fitosporin-M”, “Glycladin”, “Gamair”. If you mulch the soil around the bush, then watering with these preparations should be carried out monthly;

Acidified soil

If the soils are acidic, and over time, acidification of any soil occurs, and you have not carried out deacidification for a long time, then sprinkle stove ash around the bush. Such an event should be held every fall;

“Overfeeding or underfeeding” - what fertilizers does a rose need?

Unfortunately, flowers cannot explain to people what “hurts” them. They talk about the presence of a problem with “signs”; it is important to understand them correctly. If the leaves of a rose turn yellow, this may be a signal that the flower is starving. The beauty is gentle and capricious, she needs regular feeding - minerals and organic matter. If they are deficient, the leaves will turn yellow. Basic mineral fertilizers:

Organic fertilizers are always available. This includes manure, peat, herbal infusions, and compost. You should not use only one, you need to alternate them. Fresh manure is also not advisable; it can burn the roots. In the first year, the rose is not fed, provided that an organic composition has previously been added to the planting hole.

Caring for indoor roses after purchase

When you bring a rose home from the store, the first thing you need to do is carefully examine the plant. It may have darkened areas of the stem and leaves. This will indicate the presence of fungal diseases or parasites. The latter can also be seen on the plant. In this case, treatment with special preparations will be required. All stunted leaves of the flower should be carefully removed with scissors.

You will also have to cut off some of the buds. The best thing is to remove them all. The period of getting used to new conditions is difficult for indoor roses. Flowering will complicate this process, as a result of which it may die.

It is also worth paying attention to how many shoots are in the pot. If there are several of them, they are seated in different containers one at a time. This is done very carefully. After all, if the root system is damaged, the plant will not be able to fully absorb substances from the soil and develop. In this case, it will hurt and dry out.

New pots for replanting should not be too tight so that the roots of the rose can fit into them freely. At the same time, the dishes should not be too large. It is better to transplant the plant into a larger pot as it develops.

Soil for flowers is purchased in specialized stores. To prepare it yourself you will need:

• 1 Compost – 1 part.
• 2 Leaf humus – 1 part.
• 3 Coniferous soil – 1 part.
• 4 Turf – 3 parts.
• 5 Clean fine sand – 1 part.

First, drainage is placed at the bottom of the new pot, and a mixture of the listed components is placed on top. The rose moves there along with the near-root lump of earth. The soil is lightly cleaned to inspect the condition of the roots. If there are dark, rotten or dried roots, they are removed. Healthy roots have a fresh white or slightly yellowish color.

After transplanting and fixing, the plant is immediately watered. This is done with water at room temperature. After this process, it would be useful to treat with special preparations to strengthen the immune system and prevent fungal diseases and parasites.

The next step is to choose the optimal place in the house where the rose will be comfortable.

It is recommended to place pots with plants on sunny southern windowsills. At the same time, the rays should not directly hit the flower. It is very delicate and can cause burns. It is better to choose a light color for the pot, as the dark color will attract excess ultraviolet radiation. If necessary, install additional lighting sources - lamps.

The room where roses are placed must be ventilated daily. There should be no drafts. Increased dryness and humidity are harmful to the plant. The most suitable temperature is from +18ºС to +25ºС.

Even if everything is done and taken into account, the rose may hurt for some time. This is a normal reaction to a change of location and can last up to 2 weeks. If leaves fall during this period, do not worry too much. But their darkening will already indicate a serious disease of the flower.

What to do if a rose in a pot dries out?

• If a profusely flowering bush, recently brought from a store or received as a gift, suddenly begins to shed its leaves, do not panic, frantically moving it from place to place or increasing watering. In this way, the plant is most likely simply reacting to new conditions. The pot with the newly purchased indoor rose must be placed in a well-lit, warm place that prevents drafts. The best option for its placement is the window sill of a south-eastern or eastern window. After the rose gets used to the new environment, the leaves will stop falling.
• It is much worse if flowers and unopened buds wilt, and the leaves not only fall off, but also turn black. This symptomatology is typical for plants that have been subjected to freezing, fungal infection or attack by insect pests. That is why a pot with a newly purchased rose should not be placed on the same windowsill with other indoor plants. It is better to keep the flower separately for two weeks, carefully monitoring its condition.
• Homemade rose dries in an overly hot room. You can cope with this problem by placing the flower pot in a tray filled with wet expanded clay or moving it away from the central heating radiator, while not forgetting to check the degree of soil moisture in the pot. If it turns out to be insufficient, the flower needs to be watered and then the leaves should be sprayed with a spray bottle.
• Very often, indoor roses dry out due to rotting of the root system, caused either by too frequent watering, which leads to waterlogging of the soil, or by the presence of an overly dense substrate that does not have time to dry out after the next watering. What to do in this case? Having freed the roots from the old soil, the rotten areas (they will be soft, black and transparent) must be removed, and the healthy ones must be washed in a weak solution of potassium permanganate. After this, the root system is kept in a solution of the fungicidal drug “Fitosporin-M” for half an hour. Having taken the bush out of the container with the solution, the roots are dried in air for two hours, and then transplanted into another pot filled with fresh, fertile and loose soil. The transplanted rose is not watered, but only sprayed once a day. Ten days later, the plant is watered with a solution of the same fungicide.
• If the root system of an indoor rose is damaged beyond repair, you can cut several cuttings from the bush and try to use them for further propagation of the plant.
• If the leaves of indoor roses begin to turn yellow, you need to check the soil in the pot: it may be over-moistened. In this case, you should refrain from watering for a while, limiting yourself to spraying the leaves. If there are signs of soil acidification, the rose is replanted using a specialized substrate purchased at a flower shop (it is better to avoid using garden soil). A yellowing rose can be fed with complex fertilizer (Bona Forte and Greenwold produce good results).
• Evidence that the rose is dying as a result of an attack by parasites (thrips, spider mites or aphids) is the appearance of cobwebs, eaten or speckled with dark spots on the leaves, as well as the appearance of insects that are easy to visually observe. You can cope with pests using insecticidal preparations “Aktellik” or “Fitoverm” (several treatments with a seven-day break will be required).
• There is an easy way to rid your indoor rose of spider mites. After thoroughly washing the sponge with a bar of laundry soap, the resulting foam is generously applied to the stems, leaves and soil surface. After half an hour, the foam is carefully washed off with running warm water from the shower head.
• If home roses wither as a result of aphids, you can resort to an infusion prepared from orange peels, poured with boiling water and infused for 48 hours. After spraying the leaves of the affected plants with undiluted infusion, they are covered with cellophane film and left overnight. In the morning the film is removed. New leaves on the bushes appear, as a rule, by the end of the second day. To prevent the appearance of new parasites, the treatment can be repeated.
• Lightening of the leaves of indoor roses can be a consequence of chlorosis. You can cope with the disease by feeding them with mineral fertilizer containing a full range of microelements.
• What to do if an indoor rose has dried out as a result of damage to the root system? You can resort to the help of root formation stimulants, represented by the drugs “Heteroauxin” or “Kornevin”. The roots of the plant, removed from the pot and freed from soil, are placed in a container with a freshly prepared solution for 6-8 hours. After this time, it is transplanted into another pot using a light, fresh substrate.
• If a newly purchased indoor rose sheds its leaves too intensively, you can shorten the branches by 5-6 cm and water it with a solution of a growth stimulator (it is best to take Epin). This manipulation will help the plant cope with stress faster. To prevent the occurrence of chlorosis, after 15-20 days the same plant must be watered with a solution of the drug “Ferovit”. Every 15 days you will need to water it with water acidified with lemon juice (3-4 drops of juice per 100 ml of water).
• If, despite a whole range of measures taken, the leaves continue to wilt, and the green shoots dry out, becoming wrinkled and brown, the soil in the pot can be watered generously. The above-ground part of the bush must be immersed in a basin of cool water and left in it for two hours. You can do it easier by placing a pot with a fading rose in a basin of water. The liquid will seep into the soil through the drainage holes at the bottom of the pot.

Why does indoor rose dry out?

Indoor roses dry out for several reasons. The main ones:

• unfavorable indoor conditions;
• improper care of the plant;
• root damage;
• infection with fungal diseases;
• presence of dangerous pests.

If the rose has dried out, the reason is most often failure to follow the basic rules of caring for it: timely and moderate watering, maintaining normal temperature and sufficient humidity in the room. A change in leaf color to yellow indicates damage to the roots, lack of nitrogen, iron and some other essential elements in the soil.

Excessive soil density prevents the free flow of nutrients from the soil to the rose roots. This also complicates the absorption of moisture, as a result of which the soil in the pot does not have time to dry out. Because of this, the flower will also wither and shed its leaves.

Prevention measures

Preventative measures are very important. They help reduce the risk of various chlorophytum diseases

Lovers of indoor plants who are planning to add this plant to their collection or have it in their collection are advised to pay special attention to preventive measures

For a plant to grow well, it needs good soil. You should choose the right soil for this particular flower. When purchasing soil, it is better to give preference to a substrate that has neutral acidity. You should choose a substrate that allows water and air to pass through perfectly. To reduce the risk of various parasites appearing in the substrate, before using it for planting or replanting a plant, it is recommended to treat it

Thus, the soil can be calcined or treated in a water bath (depending on the type of soil substrate). An important preventive measure is compliance with all microclimate indicators. It is better to place the plant in a well-lit place, and also monitor the optimal temperature and humidity in the room

If for some reason the air in the room where the flower “lives” decreases, then it is recommended to think about the possibility of purchasing special home air humidifiers - humidifiers. Having such a device in a home where air humidity is reduced is a necessity, not a luxury. To keep the leaves and roots of the plant in good condition, you should not forget about regular watering. It is better to water the flower with water that has been previously settled. We should not forget about transplantation. Experts recommend carrying out this procedure only when necessary. Some (especially beginners) home plant lovers abuse replanting. This often leads to the fact that in the future the flowers begin to grow poorly due to damage to the root system. In order not to damage the plant, it should be replanted correctly - in compliance with special technology. Another important preventative measure is to conduct regular plant inspections. To do this, you need to inspect the leaves. During this “home inspection” you should pay attention to the color and elasticity of the foliage. And also, upon examination, you can notice pests and parasites on the leaves. If they were discovered, then you should not hesitate to carry out treatment. Delayed treatment can lead to the death of the flower.

Improper care

If a rose in a pot withers, you should pay attention to the condition of the soil. The plant loves water, but it should not be flooded. Excess moisture causes mold to appear and roots to rot.

Improper care can cause the plant to wither. It will dry when located near sources of heating of the premises. House roses should be kept away from them. If this is not possible, the following measures are taken:

• additional hydration of the bush by more frequent spraying;
• installation near water containers;
• laying wet expanded clay in a tray.

The air humidity in the room must be monitored. Due to increased dryness, the plant dries out and dies. It doesn’t hurt to occasionally wipe the leaves with a clean, damp cloth.

Correct light conditions, optimal temperature and humidity, timely watering - these are the basic conditions necessary for a rose. At the same time, everything should be in moderation: lighting and moisture. Periodic inspection of the bush for the presence of parasites is another necessary measure. Insects destroy the plant and it gradually dies.

Aftercare

In order for a flower to delight its owners with green foliage throughout the year, it is imperative to properly care for it. The microclimate indicators of the room where the plant is located must be within a certain range.

One of these important indicators is temperature. The plant grows quite well if in summer the room where it is located is maintained at a temperature of +21 to +24 degrees. Minor changes in the temperature regime do not have a significant negative impact on the life processes of the plant. However, experts advise not to allow the temperature in the room where this plant is located to drop below +12 degrees during the winter season. Otherwise, the flower may simply freeze and get sick.

Humidity is another important indicator that chlorophytum lovers are recommended to monitor. While the plant is actively growing, it is desirable that this microclimate indicator be 70–75%.

It is recommended to maintain this humidity during the warm season. In winter, it is enough for this figure to be about 50%.

House plant lovers quite often ask botanical experts whether chlorophytum needs any feeding. Experts note that in some cases, for example, when the color of leaves changes or when growth is poor, special combined products can be used to improve the functioning of plants. You shouldn't do this too often. As a rule, complex fertilizing to improve the growth of chlorophytum can be used 1–2 times a month.

Liquid complex products for decorative indoor plants or preparations intended for flowering plants are suitable for flowers.

Chlorophytum is a plant with abundant foliage. To keep the leaves elastic and brightly colored, they need enough moisture.

Regular watering is an important component of proper care of this plant.

During active growing season, experts recommend watering this flower 2-3 times a week. At the same time, the flower does not require too much moisture, as this can lead to damage to its root apparatus.

Chlorophytum is a flower that “loves” to be in fairly well-lit places, but the light should be diffused. Active and even excessive insolation can lead to damage to the delicate leaves of the plant. It is recommended to place this flower in rooms with windows facing south, southeast and southwest

It is important to monitor the condition of the flower. If the insolation during the day is too intense, then in this case it is better to move the plant to a less lit place in the afternoon

Dangerous pests

Aphids, thrips and spider mites are the most common pests of house plants, due to which they often get sick and dry out. They are easy to spot. Usually both the insects themselves and traces of their activity are visible. The presence of parasites is indicated by gnawed areas of indoor rose leaves and small dark spots on them. The presence of a tick will be revealed by a spider web, which is usually located under the foliage. If such signs are found, it means that the flowers wither for this very reason.

All affected parts of the plant are carefully removed. Then treatment is carried out with special solutions against insects. It is recommended to do this as a preventive measure in the summer, even if the pests are not visible.

General rules for caring for roses in the garden

When planting roses in open ground, the following should be considered:

Selecting a seat

Why do hydrangea leaves dry at the edges?

The place for the garden rose should be well lit. When planting several bushes at once, you should place them so that low plants are in the foreground, and taller plants are moved back to avoid shading. In shady conditions, garden roses grow much worse, they practically do not bloom, and dark spots form on the leaves.

On a note! To avoid the development and spread of fungal diseases (primarily powdery mildew), the plantings should be provided with a sufficient level of air circulation; however, a strong draft is no less dangerous for roses.

The soil on which roses will be cultivated must first be well loosened. The soil must be saturated with nutrients, and the depth of the fertile layer must be at least 40 cm. Wetlands are absolutely not suitable for plants. Plots with close groundwater should be avoided.

Preparing the soil for planting

The most effective way to prepare a site for planting roses is also the longest. In this case, they use old newspapers, which are laid out on the surface of the plot in 8-12 layers and fixed with something so that they do not fly away. The plot is left in this state for 2 months. During this period, all weeds will die under such cover, and the soil will soften greatly and will be easier to dig up.

Planting roses

After this, you need to determine the acidity of the soil. The optimal pH level for roses varies from 6 to 7. If the soil is acidic, the situation is corrected by adding lime.

Next, dig a planting hole into which fertilizer is added. If superphosphate is used, you need to make sure that the drug does not come into direct contact with the roots of the rose. The substance is placed in the hole, covered with soil, and only after that the plant is placed there. In most cases, a drainage system is formed in the hole, for which large crushed stone, branches, and expanded clay are used.

Note! It is also recommended to pour 250 g of bone meal into the hole.

Landing

If roses are planted in the spring, you need to wait until the soil is warm enough after thawing. In most regions of Russia, the optimal period for planting roses begins in the last ten days of April and lasts until mid-May. You shouldn’t delay planting either. At the end of spring, the soil is already heating up quite strongly, and it will be difficult for the plant to take root and grow normally in such conditions. Even after taking root, the plant will be weak in such conditions outside and will begin to shed its leaves and buds.

It is also possible to plant in the autumn. To do this, select the period from the second ten days of September to the second ten days of October. At this time, the weather is relatively warm, the soil has not yet had time to cool and contains a significant amount of moisture. At the same time, in regions where autumn is rarely warm and long (in Siberia), planting dates are moved to the end of August-September.

To plant or replant a plant in the fall, you need to prepare the planting hole a month and a half before the procedure. In any case, at least 20-30 days must pass after planting and before the first frost begins.

For your information! The size of the hole should be sufficient for the plants to feel free. On fertile soils, a hole depth of half a meter and the same width is sufficient. In clayey areas, the width remains the same, but the depth increases to 60-70 cm.

When the hole is ready, pour water into it and wait until the liquid is completely absorbed. After this, plants with a closed root system are placed directly into the hole. If roses have open roots, then their tips are shortened by a third, and then placed in a solution of water or a root formation stimulator for several hours.

A low earthen mound is formed in the center of the hole. The plant is placed on it, and the roots are spread throughout the hole. In this case, the root collar should be located at least 5 cm below the surface of the hole. Then the hole is covered with earth. For convenience, a shallow side is dug in the bite sector, which will prevent water from spreading.

Important! Upon completion of planting, the plants should be watered well.

The rosette reacts negatively to crowded plantings and can be affected by diseases and shed leaves in such conditions. Therefore, the flower needs to be provided with sufficient spatial isolation. Depending on the specific species, this figure ranges from 50 cm to 1 m. However, this distance may vary depending on the purposes of plant cultivation. Thus, bush roses also look great as single planted plants, while in rose gardens the above distance between two plants is maintained.

Subsequent care for planting indoor or outdoor roses involves the following procedures:

• irrigation;
• feeding;
• trimmings;
• pest and disease control;
• transplantation if necessary;
• reproduction, etc.

How to cure a rose

In most cases, fading flowers can be saved.

How to revive a rose that is withering due to mistakes in care:

• 1 Move to a bright place away from radiators, heaters, etc.
• 2 Monitor the temperature.
• 3 Ventilate the room, avoiding drafts.
• 4 Water as soon as the soil in the pot is slightly dry.
• 5 Regularly irrigate the bush.
• 6 Use water for irrigation and spraying that has been settled to room temperature and purified through a filter to remove impurities.

The rose bush withers from too much watering. In this case, you should only get by with spraying. If the soil in the pot is too flooded, it would be better to replant the plant. Humidification through a tray will help avoid such problems. The rose will absorb the required portion of water, after which the excess should be drained.

High soil moisture not only prevents the flower from better absorbing nutrients, but also causes fungal diseases. The presence of such will be indicated by foreign growths on stems and leaves, plaques, darkened areas, plaque, and powdery mildew. Treatment with antifungal agents is required here. Fitosporin is good.

How to care after purchase?

A homemade rose bought in a store is in the flowering stage. Such a plant is treated with growth stimulants and must be cared for somewhat differently than a plant grown at home:

• First of all, the flower is removed from the packaging to provide access to fresh air.
• The rose is examined by cutting off all the dried leaves and buds.
• Then rinse under a warm shower, washing away possible pests.
• It is a good idea to carry out preventive treatment of the bush against fungus.
• The pot is placed in the place where it is supposed to be kept and left for adaptation at home.
• After 2-3 weeks the bush can be transplanted. This can be done in winter, since the plant will not be in a state of winter dormancy.
• The rosette is provided with comfortable living conditions: warm water is sprayed, watered, and additional lighting is provided if necessary.

We talked in detail about what care is needed after purchasing in a store in a separate article.

Why do rose leaves turn yellow?

Most often, yellowing of foliage is caused by the following reasons:

• Lack of mineral fertilizers. Depending on what the plant lacks, it turns yellow in different ways. When a crop needs nitrogen feeding, it turns yellow completely, starting from the lower leaves. Application of universal fertilizers or urea can help. If a rose lacks iron, it begins to turn yellow in spots - from top to bottom. In this case, any acidifying fertilizer will do.
• Excess feeding. Excess mineral fertilizers can also lead to leaf fall. When the flower is weakened and you want to feed it, it is better to start with half the dose, otherwise you can burn the roots.
• Pests and diseases. One of the most common diseases is chlorosis. You can fight it with the help of Antichlorosin, which dissolves well in water. The plant is watered with it twice during the growth period, and then once every two weeks, if necessary.
• Excessive humidity. Although roses love moisture, excess is harmful to it, otherwise it will begin not only to turn yellow, but also to rot. Finding a middle ground is not difficult - it is enough to provide good drainage and water the plant as soon as the top layer begins to dry out. In addition, it is useful to spray it with warm water from a spray bottle.

Care errors

Symptoms. The rosette dries up, sheds its leaves, the buds wither, the ends of the shoots turn brown and dry out.

Cause. Insufficient watering, low air humidity.

Treatment. Cut off all dead branches to a height of 3-4 cm from the main trunk, as well as all dry twigs and yellowed leaves. Water the rose, place the pot under a plastic bag to ensure high air humidity under the shelter. When new shoots appear, begin to ventilate the greenhouse and accustom the rose to dry air. If the rose has wilted but not shed its leaves, try soaking the entire pot in water for 5 minutes and spraying the plant, or even soaking the whole plant in a bathtub for 2 hours, wrapping the pot in a plastic bag. If symptoms appear in the fall, don't worry—the rose is preparing for winter.

Symptoms. The rosette dries up, sheds its leaves, the buds wither, the shoots turn brown and rot.

Cause. Too much watering, frequent spraying in a cold room.

Treatment. It is more difficult to revive a rose that has been “overwatered” than “underwatered.” You need to remove it from the pot, clean the roots from the soil and inspect them - if not all of them are rotten, cut off the damaged ones and replant the rose in new soil (the old one may be sour), water it moderately, but not allowing the coma to dry out completely.

Rules of care

1. Once you have bought a rose bush you like and brought it home, do not rush to replant it. Place the plant on an east or southeast window and let it get used to the new microclimate.
2. Roses are watered as often as the soil dries out. Watering is carried out with settled (at least 24 hours) ordinary tap water at room temperature.
3. Roses respond well to spraying their leaves. Spraying of roses is carried out in the evenings with cold boiled water or a solution of special fertilizers in cold boiled water. The underside of rose leaves is sprayed with a spray bottle that produces a misty spray. But you shouldn’t spray roses every day, even in summer.
4. As soon as the moon enters the growth phase, it is a good time to replant the plant. Transplanting roses from a container into a pot must be done carefully - without destroying the clod of earth or disturbing the roots. There are often white or gray granules of complex fertilizer on the roots of roses; these do not need to be removed or washed off. Before replanting, remove a small amount of old soil from the top of the earthen clod, carefully loosening and removing it without damaging the roots.
5. Roses need nutritious soil for good growth: a mixture of 4 parts turf, 4 parts humus soil and 1 part sand. When planting, granules of complex fertilizer must be added to such soil. If you do not have the opportunity to prepare the necessary components for the soil mixture, then roses can be planted in ready-made purchased soil.
6. A new rose pot should be larger than the container in which the plant was sold, at least 2-4 cm in diameter and 5-7 cm in height. You shouldn’t take a pot that’s too big either; The above-ground part of the plant should correspond to the volume of the pot as 1:1. If the pot is ceramic and completely new (nothing has grown there yet), then before planting the roses it is first soaked in warm water for 2 hours (this is especially necessary if the pot is unglazed). If something has already been grown in a pot, wash it well with a stiff brush in warm water, but without soap.
7. A drainage layer (preferably expanded clay) about 1 cm thick is placed on the bottom of the pot prepared for transplanting the rose. If the pot does not have a drain hole (and it is impossible to make this hole), then the drainage layer should be at least 3 cm. Earth mixed with fertilizer granules, then sprinkled with a layer of soil without fertilizer.

What will save a rose from pests?

Rose is treated with two types of preparations:

insecticides - against insects (fitoverm, actelik), fungicides - against fungal diseases (quadris, chorus, ridomil). There are also mixed preparations. Dosages are indicated in the instructions. For indoor conditions, fitoverm, for example, is more acceptable because it is less toxic. You can also use the same preparations that you usually use to treat tomatoes in the country against late blight. But reduce the dosage by half. Try to buy licensed drugs.

Rules of care according to the seasons

Summer

In summer, caring for a rose consists of watering, spraying, fertilizing, and removing faded flowers (the peduncle is trimmed with pruners or a sharp knife to the first formed leaf bud). It is necessary to monitor the condition of the plant (so that the rose does not overheat; notice signs of diseases and emerging pests in time). If the rose is growing very quickly, and the chosen pot has become too small for it, wait until the moon grows and transfer the plant to a new, larger pot. If a rose stands on a window and is illuminated from one side, it, of course, reaches out to the sun. In order not to get a one-sided bush, the rose pot must be turned from time to time to ensure uniform illumination of the bush.

Autumn

In autumn, when the night temperature drops to 15-12 degrees, the rose from the balcony is moved into the room and placed on the windowsill of the south window. When the rose stops blooming and forming buds, it is prepared for wintering: water less frequently (leaving the soil dry for a day or two before watering) and stop feeding. If possible, for wintering the rose is placed on the windowsill of a cold room with a window (in winter the air temperature in it should not be higher than 15-17 degrees). In an ordinary apartment with central heating, options are possible: a rose is placed between the frames for the winter; or they don’t seal up the window on which the rose overwinters in the fall; or fence off from the rest of the room with plastic film the part of the window on which the rose overwinters. In any case, there should be no electrical or heating appliances (computer, TV, radiator, etc.) near the wintering rose.

Winter

Before placing a rose for the winter, it is usually pruned, leaving 5 live buds on each branch; leaves are not removed. Pruning is carried out when the moon is in its growth phase. If pruning is not carried out in the fall, then in the summer of next year the rose will bloom much later, the flowering will be less abundant, and the bush will not look very neat. If you did not prune the rose before wintering, pruning can be done in the spring.

In winter, the rose will not grow and bloom, but will shed its remaining leaves and look very sad; At this time, caring for the plant consists of rare watering (after the soil dries, water after 2-3 days) and spraying. When wintering a rose in a room with central heating, it is recommended to place the pot with the plant on a tray with wet pebbles or gravel and make sure that the stones are always wet - this will protect the rose from excessive dry air.

Spring

In spring, the rose appears new leaves and twigs. At this time, they begin to water it more abundantly; the dried soil remains dry for no more than one day until the next watering. At the beginning of growth, the rose must be fed with complete mineral fertilizer, or a solution of mullein or bird droppings.

• Mullein solution: place 1/3 mullein and 2/3 water in a container, close it and leave for 3-4 days, stirring occasionally. After fermentation stops, when the solution becomes lighter, it is ready (fermentation time depends on temperature, sometimes it takes 1.5 weeks). The prepared mullein solution is diluted with settled tap water in a ratio of 1:15 (one part of the solution to 15 parts of water) - the fertilizing is ready.
• Bird droppings solution: one part of bird droppings is poured with 200 parts of hot water and left for two days. The finished solution is diluted with settled water in a ratio of 1:25 (1 part solution to 25 parts water) and used for feeding.

The rose is fed after regular watering. To produce large flowers, as soon as the buds begin to form, the rose must be fed once a week. During the growth period, during the formation of buds, the rose should not lack moisture or light. The plant is placed in the brightest window, watered as the soil dries with settled water, and in the evenings it is sometimes sprayed with cold boiled water from a thin spray bottle. As soon as the plant has outgrown the pot, it must be transferred, without disturbing the roots, into a larger pot. It doesn’t matter what season of the year the rose is transplanted; If necessary, you can replant even in winter, but the moon must be in the growing phase.

When the spring frosts pass and warm night temperatures set in, it’s time to take the rose out to the balcony or garden. In the first weeks, the rose must be gradually accustomed to the bright sun. To do this, the plant is first placed in a shady corner of the balcony or garden and only after about two weeks is transferred to a sunny place. If there is no shady corner, use a “sliding shadow” from a sheet of thick paper with 8x2cm strips cut in a checkerboard pattern. Cover the rose with this leaf for 2-3 weeks.

Diseases that cause yellowing of roses

One of the common diseases of indoor roses is powdery mildew. Leaves, stems and buds are affected by fungi. First, a light fluffy coating appears, then it begins to darken, and brown spots form. The leaves turn yellow, become deformed, and curl. If you do not immediately react and treat the plant, it will die. At best, its growth will stop, the foliage will fall off, and the flowers will lose their petals. The rose will lose its attractive appearance.

All affected parts of the plant will have to be removed, otherwise it will not be possible to defeat the disease. It spreads rapidly and also easily spreads to neighboring flowers. Spores are carried on the hands after working with an injured representative of the flora, and easily move through the air.

Note! At the early stage of the disease, when the leaves seem to be sprinkled with flour, and the plaque is wiped off with your fingers, you can use a solution of soda with added soap. If the plant does not recover, it is better to resort to fungicides

Black spots may appear on the leaves of indoor roses. They have jagged edges and are clearly visible. At the same time, the leaf blades themselves turn pale, turn yellow, and wither. Over time, the spots grow and merge, and may appear on shoots. Plant growth slows down and flowering does not occur. The affected leaves fall off, new shoots are formed, which do not have time to gain strength and immediately encounter the disease. A systemic fungicide will help cope with it. The substance penetrates the plant and promotes its recovery.

If yellow-red spots are noticeable on the rose, then rust has appeared. The main reasons are high temperature at home and stale air when the room is rarely ventilated.

Rust appears due to stuffiness

Pests and feeding

Rose, like many other indoor plants, is very afraid of spider mites. Determining the presence of such a pest is quite simple. The leaves begin to fall and small bugs can be seen climbing on them. If you turn the leaf over, you can see a characteristic white coating on its back side. To solve this problem, you need to use special preparations that are sold in flower shops. Spraying the flowerpot is carried out according to the instructions on the product packaging.

Roses are quite capricious and demanding plants. For normal flowerpot growth you will need a sufficient amount of minerals and trace elements. A lack of any element will negatively affect the plant. So, if a flower lacks magnesium, its leaves begin to fall off over time. In the case of a lack of nitrogen, they stop growing and change their color. To prevent such changes, it is necessary to feed the plant in a timely manner. To do this, it is worth using special fertilizers designed specifically for flowering flowerpots.

A common cause of discoloration and falling leaves is excessive flowering. The development of buds and flowering takes quite a lot of effort. When there is a lot of color, the leaves become defenseless and are easily susceptible to diseases, pests and various changes. This problem is solved with the help of special fertilizers and preparations that are sprayed on the flowerpot. With their help, you can strengthen the flower’s immunity and supply it with all the microelements and minerals for full growth and development. All medications must be used in accordance with the instructions.

Pests

Sometimes the leaves of indoor roses slightly change color to a lighter shade, which many confuse with yellowness.
At the same time, the old leaf plates begin to wither, and the young ones grow deformed and pale. This indicates the presence of pests in the root system area. Carefully move the soil away from the base of the trunk and a little deeper. This is where harmful larvae or worms live. Some sources recommend catching parasites with tweezers. Give it a try. And it’s good if there was only one worm. What if the soil was more contaminated? Are you going to use tweezers all over the pot? During this time, the indoor rose will simply bend.

Don't rely on your sleight of hand, it may not be enough. Use any broad-spectrum or long-lasting systemic insecticide. Be sure to repeat the soil treatment in a month.

Advice. Be sure to replant your indoor rose from store-bought soil into your own. But only after disinfection by freezing or heating in the oven.

Improper watering

If you water your flowers incorrectly, you can seriously harm them. Cold water should not be used to water roses. As a result, the bush becomes sick, stops growing and dies over time. The water should be soft and settled. Some gardeners advise boiling it.

The frequency of watering can be selected according to the condition of the soil in the pot. If its top layer begins to crack, moisturizing is necessary. Mature plants are watered two or three times a week. In the summer heat, you can water them more often and install a humidifier in the room.

The foliage of indoor roses often turns yellow due to improper watering of the plant. This can be either overwatering or insufficient watering. Overdrying of the flower, in addition to its yellowing and loss of leaves, may also be indicated by a general depressed appearance and the appearance of cracks in the soil. If overwatering occurs, the symptoms will be somewhat different: yellowing of the foliage in this case is accompanied by lethargy of the plant, its wilting, and the presence of a “swamp” in the pot.

Preventive measures

Prevention of shedding of leaf plates is carried out by creating the most comfortable conditions for the crop:

• bushes are planted in sufficiently illuminated areas, where in the summer the sun's rays are present for at least 5 hours;
• avoid planting in wetlands where groundwater will flow to the root system;
• water correctly. During the hot period, each bush needs a full bucket of warm water weekly; during drought, the frequency increases to 2 times a week;
• regularly feed the crop with special fertilizers for roses;
• regularly carry out preventive treatment of the rose garden with fungicidal and insecticidal preparations;
• do not forget about pruning branches and stems;
• protect shrubs from strong, cold winds.

For indoor varieties there are their own preventive measures:

• mandatory supply of fresh air without creating a draft;
• after flowering ends, watering is stopped;
• when pruning, plants are shortened to 10 cm, leaving an outer bud;
• Improving immunity is carried out with the biostimulator zircon or epin.

Important! Experienced flower growers note that attempts to water tea and other roses with cold tap water provoke the development of diseases. You need to use it before settling for 72 hours at an air temperature of 22 °C.

Problems with yellowing and shedding of leaf blades in roses are in most cases associated with violations of crop care requirements. If you strictly follow the recommendations, most problems will be avoided by your home rose garden. In addition, modern varieties have been bred to be resistant to most diseases and insect pests.

Possible reasons

There are several sources due to which fallen roses are observed on the site. An incorrectly selected planting site, improper care and other prerequisites become catastrophic for the plant.

Problems with sunlight

Why do Decembrist leaves wither and fall off - what to do

Why do leaves fall off on street roses? These plants prefer diffused light rather than hot and scorching sun. Constantly high temperatures cause burns on the foliage and their shedding.

Being in the shade provokes a weakening of the immune system; roses will lack the ultraviolet spectrum for normal growth and development, and its deficiency will negatively affect the formation of buds.

Important! Before planting a shrub, you need to decide on a location. The best option is considered to be an area illuminated until noon. In the afternoon, it should be protected from constant exposure to sunlight.

Sunburn on leaves

Watering problems

Common reasons why a rose suddenly drops its leaves include violation of soil moisture rules. Lack of moisture in the heat provokes drying of the bushes, and its excess causes rotting of the roots. Overmoistening can be determined by yellowing of the foliage and blackening of the shoots.

Important! The area where the bush will grow should not be located in the area of ​​close contact with groundwater. During the growing season, it should be watered weekly, depending on weather conditions.

Root rot

Nutritional deficiency

A constant lack of nutrients has a detrimental effect on the condition of the plant, which provokes the dropping of leaf plates:

• pale, small foliage with reddish spots and a minimal number of buds indicates a nitrogen deficiency;
• drying of the edges of the foliage, transformation of the main color into a reddish-violet tone and massive falling off indicates a lack of potassium;
• pronounced yellowness of the green part of the plant requires an increase in iron;
• a dark green tint of leaves with a red or purple tint, violet-brown spots and stripes, a change in the color of the stems to purple indicates a lack of phosphorus;
• colorless spots on old and young plates with dead dark red areas in the vein area are caused by a lack of magnesium.

Important! An insufficient amount of copper leads to a whitish color of the tips of the foliage, loss of elasticity and wilting.

Deficiency of nutrients

Rose diseases

The list of common diseases that cause leaf loss includes:

• Botrytis. Leads to the appearance of brownish wet spots with a gray coating on the leaves. Over time, they curl, dry out and fall off. The buds do not open, turn black and die. The appearance of the disease is provoked by high humidity with low temperature, excessive planting density and overfeeding with nitrogen.
• Powdery mildew. Identified by curling of leaves and a gray-powdery coating. It is provoked by high humidity and temperature, planting density, excess nitrogen, lack of calcium and dry soil in the root area.
• Perenosporosis. Causes rounded red-brown spots; a loose whitish-silver coating forms on the underside of the plates. Young shoots dry out, there is no flowering, old branches become covered with ulcers and cracks. The appearance of fungus is associated with abundant watering, hot or damp weather.
• Rust. It affects all parts of roses; rusty spots are visible on the upper side of the plates, and small red-yellow pads on the bottom, in which spores ripen under favorable conditions. By mid-season, black spots filled with winter spores appear on the foliage. The appearance of pathology is promoted by cold spring and lack of potassium.
• Black spot. Identified by rounded radiant spots of dark brown color with a yellow edging. Under the upper layer of the plates, the fruiting bodies of the fungus ripen, causing it to rupture and disperse the spores. The bushes begin to shed damaged foliage. The disease occurs with potassium deficiency and high soil moisture.

Important! Roses are susceptible to attacks by fungal infections; Alirin-B, Glyokladin, and Topaz are used to combat them.

Black spot

Pest exposure

Loss of foliage may be due to parasitic insects. The list of common pests includes:

• gallworm;
• spider mite;
• slobbering pennice;
• rose leafhopper;
• pink scale insect;
• thrips;
• aphid.

All of these representatives are sucking insects that cause plants to dry out due to loss of juices. You can get rid of pests by spraying with store-bought insecticides.
