Why calla lilies do not bloom in open ground and what to do, how to make them bloom

Why doesn't calla lily bloom?

The flower's habitat is the tropical forests of America and East Asia, so in harsher latitudes problems may arise when growing it in open ground. In indoor conditions, with proper care, calla lilies can bloom all year, interrupting for the winter. However, sometimes the plant does not bloom. As a rule, the reason lies in improper care and unfavorable living conditions.

At home

If the crop is grown indoors, the reason why calla lilies do not bloom may be due to inappropriate temperature conditions. The shrub needs a warm room. Sudden changes and drops in temperature negatively affect the normal development of the flower.

Common reasons that calla lilies do not bloom:

Insufficient air humidity in the room. Her performance should be above average. To increase humidity in dry air, you need to spray the plant with a spray bottle more often.
Incorrect feeding or its irregular application. The high nitrogen content during the growing season helps callas gain leaf mass rather than set buds.
No replanting, especially in the first years of flower growth. This provokes a stop in flowering and development of calla lilies in general. The root system grows and it becomes crowded in the pot.
Lack of natural light. Because of this, photosynthesis and other natural processes in plant cells are slowed down.

Note! If you purchased an adult plant, perhaps the reason for the lack of flowering is that it is currently dormant.

Outdoors in the garden

Most of the reasons why calla lilies do not bloom in an apartment indirectly relate to the problems of growing flowers in open ground. Wrong choice of location and errors during planting or transplanting are the most common problems.

Often, infection occurs through contaminated garden tools, which provokes the appearance of diseases. Poor quality planting material also affects the inability to set buds.
If you water the bush incorrectly or use hard and cold water, you may not only not wait for flowering, but also completely destroy the flower.
During the growing season, the crop needs feeding. When choosing a place for a flower, you should beware of alkaline soil; you need to oxidize it with humus or rotted manure.
Often, after propagation by vegetative methods, calla lilies do not bloom. There is a high probability that mechanical damage was caused to the root system or shoots.
It is worth paying attention to the age of the shrub; perhaps it is still too young to bloom.

There are many reasons for calla lilies not blooming.

Tips and tricks for gardeners

If you want to acquire such a luxurious and profusely flowering plant as calla lilies, then you must adhere to the following recommendations:

You need to place the flower pot on the windowsill, where the sun shines in the first half of the day.
The container for transplantation should be spacious, with a height of at least 60 centimeters. The radius from the calla lily's growth point should be 20 centimeters.
You should not ignore feeding procedures; the flower responds to them with gratitude. Not only ready-made nutritional compositions, but also traditional methods are suitable for these purposes. You need to form a groove around the decorative planting and place fragments of fruit peels and seed husks in it. They should be sprinkled with soil mixture.
Irrigation activities must be carried out exclusively with filtered water or at room temperature. Watering and tea leaves are also useful.
To avoid troubles when growing an African guest, it is necessary to remove the top layer of soil and replace it with a new, fertile one. The main thing is to do everything with caution, otherwise there is a high probability of injury to the root system. This technique allows us to further reduce the frequency of transplantation work.
White varieties of calla lilies require more moisture than colored ones; bright light is more important for them, and you should not throw them away if they have dropped their leaves during the rest period.

It is not for nothing that callas occupy one of the leading positions among ornamental crops used in home floriculture. This unpretentious plant grows and develops quite normally in room conditions, the main thing is to maintain a certain temperature regime and humidity level.

Factors causing lack of flowering

Lack of natural light.
A decrease in the required temperature or its sudden changes.
Lack of moisture in the soil.
Dry air.
A cramped pot, causing the roots to weaken.
No replanting or replacement of soil in the pot.
Incorrect dosage of mineral fertilizers, lack of nutrients in the soil.
The appearance of pests and diseases.

Important! Only after identifying the true cause of the lack of calla flowering should treatment begin.

Preparing tubers for winter

Tubers cannot be left in the ground over the winter, as they will not be able to withstand frost. They need to be dug up in mid-September, carefully inspecting the entire root system. If damage is found, they should be repaired and treated with a disinfectant. Next, the tubers are laid out to dry in a shaded place that will be well ventilated.

Tubers can be treated with potassium permanganate both in spring and autumn. If this event is carried out in the fall, then after processing the tubers need to be laid out again to dry. After this, the planting material is folded into a paper bag and placed for storage in the refrigerator, in the lowest compartment. With the onset of spring, small shoots, called children, separate from the main tuber. All material for planting is treated with potassium permanganate, after which they can be planted again.

How to make calla lilies bloom

Making calla lilies bloom again is not always easy, especially if the reason for this behavior was incorrectly identified. To prevent the problem from arising even at the planting stage, it is necessary to choose a pot of suitable size. Its volume in diameter should be 5-7 cm larger than the well-straightened root system of the bush.

Garden callas - planting and care in open ground

Planting equipment must be soaked in a disinfecting solution, and garden tools must be disinfected. It is necessary to study in advance how calla lilies reproduce, because during the vegetative procedure, both the bulbs and shoots of the bush can be damaged.

Note! If the cuts are not treated in time with special disinfecting solutions, through them the plant can become infected with infectious diseases.

Ensuring proper watering

Calla requires abundant and frequent watering. During the active period, the flower is watered 2-3 times a week. In autumn, watering should be reduced gradually. Around the end of September, the bush is watered twice a week, and then once. The procedure is continued the same number of times until the onset of spring.

A big mistake is watering calla lilies with tap water. It is harsh in composition, as it contains chlorine and other harmful chemicals. Also, do not use cold or hot liquid. You can use rain or melt water, but if this is not possible, you must let the tap liquid settle for at least 4 hours. Only then can you thoroughly water the bush with it.

Important! To settle tap water, pour it into a wide container to allow the chlorine to evaporate faster. For the same purpose, the liquid must be stirred periodically.

It is recommended to transplant the bush into a new pot in the spring.

Transplanting calla lilies into a spacious pot

Calla lilies will grow well and bloom on time if they are transplanted into a properly selected container. It is necessary to replant the plant as soon as it grows in size and the old pot becomes too small for it.

Step-by-step transplantation into a new container:

First, you need to take care of drainage, since calla lilies love moist soil. Expanded clay chips or small pebbles are poured into the bottom of the container so that excess water cannot stagnate in the soil.
Prepare a nutritious and loose soil mixture from light turf soil, river sand, humus and Superphosphate.
The drainage is covered with a small layer of substrate and leveled.
Place a seedling in a container and cover it with soil.
Lightly press down with your hand and water the soil around the tree trunk.
Mulch it with sawdust or pebbles slightly larger than drainage.

Providing a rest period for callas

If the calla is not allowed to rest in the winter, then it most likely will not bloom in the time allotted to it. Sometimes the flower itself does not go to winter, but instead continues to bloom. You should not be happy about this behavior, because... buds should not be allowed to bloom in winter. Every autumn, after applying the last fertilizer for the season for garden calla, you need to give it a rest until spring. If the plant does not go to rest, this must be done forcibly.

First, you need to gradually reduce the temperature and water the bush. In the last months of autumn, reduce lighting and move the bush to a dark place. The temperature of the plant during wintering should be no more than 18 °C. It should remain in this state for at least 1.5 months; in the spring, calla lilies need to be fertilized with organic matter, starting life processes.

You can feed calla lilies not only with liquid, but also with granular fertilizers

Increasing the amount of fertilizing

Before you are puzzled by the question of how to feed calla lilies for abundant flowering, you need to find out what fertilizers generally need to be used as top dressing. These are complex mineral preparations rich in phosphorus, nitrogen, iron and potassium. Closer to bud setting, the nitrogen and iron content should be eliminated from fertilizers.

Important! Poor depleted soil also needs to be fertilized with organic fertilizers: humus, manure, compost. Organics are used only during the first and last feeding, and mineral preparations – once a month.

In order to avoid problems in growing calla lilies, it is better to avoid mistakes in care

Calla lilies do not always bloom profusely and in a timely manner. There are many reasons for this behavior, but most gardeners believe that the problem is a lack of fertilizer. However, you need to familiarize yourself with all the reasons, since improper treatment can harm the flower even more. To completely avoid such problems, you should take care of the flower in a timely manner and avoid mistakes.

Caring for newly planted tubers

As soon as the callas are planted, watering should be stopped for about 1.5-2 weeks, depending on weather conditions, since the tubers already end up in fairly moist soil.
If watering is not stopped, the root system can succumb to the process of rotting and die. If after the specified period the sprouts are not visible, the flower should be slightly moistened, trying not to touch the tuber itself when watering. After the leaves appear, the bush should be watered 2-3 times a week, taking into account the weather conditions of the region.

Optimal conditions for the growth and flowering of calla lilies

Calla loves warmth and moisture. She will feel especially comfortable at air humidity of 70 to 80%. That is why it is recommended to spray the plant or wipe the leaves with a damp sponge. You can reduce the intensity of watering after flowering has ended.

Slightly acidic soil is best suited for calla lilies. The ideal combination would be a mixture of sand, soil and peat in equal proportions with the addition of humus. If this is not possible, you can water the calla lilies in universal soil with a weak solution of table vinegar at the rate of 10 ml per five-liter container of water. This method can also oxidize the soil for other plants.

Calla is very sensitive to sudden changes in air temperature. Such changes are detrimental to the vegetative system of the culture. The most optimal temperature for calla flowering is from 18 to 24 C. During the rest period, it is recommended to reduce the temperature to 10 C, but this must be done gradually. Only small daily temperature fluctuations have a positive effect on calla lilies.

By putting together all the rules and approaches to the plant, and also trying to put them into practice, the gardener can achieve good and stable calla flowering. In this case, the person will receive pleasure both from the result and from the process of care itself.
