Transplanting irises to another place in the fall: when and how best, timing and rules

Iris is considered one of the most popular and sustainable plants . It pleases the eye for a long time, not only at the time of flowering, but also after, thanks to its beautiful foliage. Every experienced gardener and florist knows that irises, if replanted incorrectly, can lose their former beauty, so this moment must be treated with special attention.

Why do you need to replant irises?

People who have not previously grown flowers do not understand why they are replanted at the end of summer or beginning of autumn. Experts recommend moving irises to another place due to the fact that they have a weakened root system. In addition, during cultivation, a young link is formed on the roots, which gradually increases in size. If the flower is not transplanted in a timely manner, it will die due to night frosts and lack of nutritional components.

Some people believe that they need to be replanted annually, but this is not true. In the first few years after planting, the plant copes with frosts. It begins to weaken gradually, and therefore flowers are planted in a new place every 3-4 years.

Favorable time for transplantation

To accurately determine the favorable time for planting flowers, you need to become more familiar with the autumn and spring timing of the work.

in spring

In regions where there are no prolonged frosts, transplantation is carried out in the spring.

In March

You can plant flowers in early spring if the air temperature does not drop below zero. Therefore, planting is carried out in the second half of the month, after warming.

In April

If the air temperature in April remains stable at 5-10 degrees Celsius, then you can begin transplanting the tubers to a new location. In this case, the procedure is carried out on a sunny day.

In May

People who prefer to replant flowers in the spring most often do this in May. The last month of spring is ideal for spring planting, as during this time the temperature does not drop below zero even at night.

Summer transfer

Some people do not have time to transplant irises in the spring and therefore do this in the summer.

In June

In some varieties of iris, root growth begins in early summer, and therefore replanting is carried out in mid-June. Experts advise replanting the plant before the summer heat begins.

In July

In July, transplantation is carried out less frequently, since the air temperature is most often high in this month.

In August

August is considered the most suitable summer month for digging and planting irises. In most varieties, intensive root development begins in this month.

in autumn

A considerable part of gardeners plant irises in the fall.

In September

Experienced gardeners believe that autumn replanting should be carried out in September, before the onset of frost. It is best to do this in the middle of the month, after flowering.

In October

People who did not have time to transplant flowers in September do so in October. In this case, flowers should be planted in the first half of the month.

In November

It is not recommended to plant irises in November, as night frosts begin this month.

Irises - description and characteristics of culture

Irises are low perennials of the rhizome family. Translated from Greek, the word Iris means rainbow. Indeed, more than 700 species of irises are known, differing in size, shape, structure and color of the flower. Externally, the iris peduncle looks like an orchid; the color of the petals is very diverse - from white and pale to rich and bright. In some varieties, the peduncle is painted with two, three or more colors, and a peculiar pattern is applied to the lower petals.

Irises begin to bloom in May and June; lush flowering can continue until the end of June. In autumn, the iris can bloom again - in August and September.

The culture has a vast geography throughout the world, with some varieties found in the harsh climate of the Northern Hemisphere. In nature, there are rhizomatous and bulbous irises, which are absolutely similar in appearance. Rhizomatous irises are resistant and unpretentious, winter well and are not afraid of cold weather. Bulbous varieties require a little more care and attention. The wildflower iris has long been loved by gardeners and has become an urban flower. You should learn everything about caring for and planting irises in open ground.

Transplant methods

Before transplanting irises, you need to familiarize yourself with the basic transplantation methods.

Technology for dividing bearded irises

The process of dividing flowers using this method is carried out in several stages:

Digging. First, the plants are carefully dug up with a pitchfork or a small spatula.
Cleaning from dirt. The dug up bulbs are shaken off and cleaned of adhering soil.
Flushing. The bulbs are washed in a solution prepared from Zircon.
Trimming. All irises are dried and carefully trimmed so that their height is 8-12 centimeters.
Transfer. The trimmed bulbs are transplanted to a new location.

Transplanting Siberian irises

To replant Siberian varieties of irises, all bushes are carefully dug out of the flowerbed. Then the new area where the flowers will be planted is fertilized with organic and mineral fertilizers. After applying fertilizer, holes are dug at a distance of 40-45 centimeters into which the irises are planted. The transplanted flowers are sprinkled with soil and watered generously with warm water.

Dividing bulbous irises

To divide bulbous flowers, you need to dig up all the plants. Then the bulbs are washed with water, soaked for 10-15 minutes in a manganese solution and dried. After this, the dried young bulbs are separated from the old ones and transplanted to another place.

What to plant next to irises

Irises share a flowerbed with other plants without any problems. Some crops saturate the soil with nitrogen, while others attract butterflies and pollinating insects.

Irises in the garden: site design ideas

You can supplement a flowerbed with irises with perennial and annual crops. Near these flowers you can plant:

onion;
peonies;
oriental poppy;
delphinium;
lupins;
dogwood;
magnolia;
birch;
willow;
heather;
rhododendrons;
rudbeckia;
clematis;
echinacea;
phlox;
lavender;
sedum

How to transplant irises correctly?

To replant flowers correctly, you need to understand the peculiarities of replanting them.

Preparing the plant

Before transplanting the bulbs, you must first prepare them. They must be soaked in a manganese solution, which is made from manganese, boric acid, cobalt and magnesium sulfate. This mixture promotes the growth of the flower and has a beneficial effect on its flowering. Soaking is carried out for 20-30 minutes.

How to prepare the soil

Despite the fact that irises are unpretentious to the soil, it is still better to prepare the area in advance. Flower growers recommend adding a little superphosphate with ash and humus to the soil. The soil is also mixed with river sand, clay and compost so that it better allows moisture and oxygen to pass through.

Rhizome division

Before dividing, all dug up bushes are thoroughly washed with water to clean them of dirt. Then the leaves with roots are cut off by a third, after which the bush is divided into planting divisions with a knife. The procedure is carried out very carefully so as not to accidentally damage the root system.

Landing in the ground

First, planting holes with a depth of 25-35 centimeters are made on the site. Then planting material is carefully placed in them. Planted plants must be watered so that they take root faster.

Autumn planting of irises

Planting irises is no more difficult than most other rhizomatous and bulbous crops. But some nuances still need to be taken into account.

There is no need to replant irises every year. The nests grow too much only in the 4th–5th year, which is when they need to be divided and replanted.

Landing dates

Planting and replanting irises should be started 5-6 weeks before the onset of persistent cold weather. In regions with harsh and cold climatic conditions, the most suitable time for planting is the end of August. In the middle zone, where the climate is slightly milder, gardeners can plant flower bulbs in the ground in early and mid-September. The weather in the warm southern regions allows these events to be held until the end of October.

The key to a successful winter will be the full rooting of the flower in the fall.

Irises planted in autumn should have time to take root before the cold weather

Irises have been growing in one place for several years and have bloomed very weakly, because the plants interfered with each other. Due to family and unforeseen circumstances, they could not be seated immediately. They got their hands on it only at the beginning of September. It was too late for a transplant, but I had to take the risk. The first frosts occurred within two weeks, and the winter was early and with little snow. Almost all the irises died.

Site selection and preparation

For irises, you need to choose a well-lit sunny area, protected from sharp gusty winds, on a small hill with a slight slope to the south, so that excess moisture is removed and the plantings are illuminated more evenly . If there is stagnation of liquid or the proximity of groundwater, it will be necessary to construct an additional drainage layer, since this crop has a superficial root system and does not tolerate excess moisture.

Irises develop better and bloom more abundantly in open sunny areas that are protected from strong winds

Irises develop and bloom best on rich, nutritious loams that have a slightly acidic or neutral reaction. Excessively acidic soils must be limed in advance using dolomite flour or fluff lime. 5–7 days before the expected planting date, the soil is dug well and the following components are added:

rotted manure (compost or humus) - 2 buckets per 1 m2;

Irises love fertile soil, so when digging the beds, be sure to add humus or rotted compost

Ash is an excellent natural potash fertilizer and deoxidizes the soil.

When planting irises in the fall, you need to apply mineral fertilizers of the potassium-phosphorus group

Nitrogen-containing fertilizers and growth stimulants are not applied to planting irises in the fall, since they cause unnecessary growth of ground mass and prevent the plant from being well prepared for wintering.

Instructions for planting irises

Planting material is pre-soaked in a weak solution of potassium permanganate for disinfection for 20–30 minutes.

For disinfection, iris rhizomes can be soaked in a solution of a special preparation for etching.

Planting technology consists of the following steps:

Dig a shallow planting hole (10–12 cm), in the center of which a mound about 2–3 cm high is formed.

First, prepare a shallow planting hole and pour a mound of earth in the middle

Between the irises leave a distance of 10 to 50 cm depending on their size

Irises are placed on earthen mounds and the roots are spread along their slopes

The rhizome of a properly planted iris is partially on the surface

Proper planting of iris in the ground

Bulbous varieties of irises are planted at a depth equal to three times the diameter of the head, usually about 10–12 cm.

Rules of care after transplantation

Transplanted irises must be properly cared for so that they do not wilt.

Watering

It is recommended to regularly water the plant to ensure it has enough moisture. In dry summer weather, the soil is moistened every day. In this case, watering is done very carefully so that droplets of water do not fall on the petals or leaves.

Trimming

Growing irises must be pruned periodically. Most often, drying flowers or leaves are cut off. To carry out the procedure, sharply sharpened scissors or pruners are used. It is contraindicated to pick leaves with flowers by hand.

Preparing for winter

Before frost, all planted flowers are covered with a layer of mulch 20-30 centimeters thick. Such a protective shelter will protect the plant from frost and help it survive the winter.

Caring for irises - basics and secrets

According to experienced gardeners, irises are strong and viable plants that grow and bloom well without fertilizer. However, in the third year of life, it is recommended to pamper the flower with step-by-step complex feeding - in the spring, during budding and after flowering. In response to care, the plant will become stronger and stronger, will grow faster and bloom more abundantly.

Irises - care in spring:

fertilizing in a ratio of 2:1:1 - nitrogen, phosphorus and potassium;
watering depending on surrounding weather conditions.

During the budding period, fertilizing should be done in a ratio of 3:1:3 - nitrogen, phosphorus, potassium. In this case, watering and spraying are carried out as necessary. A month after the end of flowering, it is recommended to fertilize in a 1:1 ratio - phosphorus plus potassium. In the autumn, before wintering, you should add dry mineral fertilizer a tablespoon at a time, scattering it under each root of the plant.

Irises should be watered at the root when the soil around the bush is completely dry. After planting, the plant is watered only after three days.

How to feed irises in spring:

if a lack of minerals is noticed, then mineral fertilizing should be applied individually to each bush;
In early spring, a complex nitrogen-potassium-phosphorus fertilizer for flowers is useful for the plant.

Prevention from diseases and pests includes sanitary pruning of dead parts of the plant, timely removal of faded flower stalks, regular spraying and showering, and cleaning the beds from fallen leaves. In open ground, iris plantings are weeded by hand, the soil is carefully loosened and watered as needed. Before winter, the rhizomes are sprinkled with earth and covered, since they are located close to the surface and can freeze.

How to protect freshly transplanted plants from diseases?

Irises, like many other plants, become infected with various diseases. To protect seedlings from diseases, they are sprayed with fungicidal agents once every 2-3 weeks. The most effective treatment is considered to be one and a half months before flowering.

Regular cleaning of the area from weeds and dried plants will also help prevent the development of diseases.
