When is the best time to do an iris transplant?
Bearded iris is a decorative, beautifully flowering plant that gardeners have long loved by their unpretentiousness in care and resistance to adverse environmental conditions. When cultivating this plant, it is very important to transplant it regularly. Why carry out this manipulation, how often and at what time of the year, read below.
Why transplant irises
To better understand why a transplant is needed, you should familiarize yourself with the botanical features of iris. The plant in question belongs to the rhizome perennials. In winter, its ground part dies, and the rhizome and axillary buds of substitution are at rest. With the onset of heat, each plant annually forms a new adventitious root 12 cm long. If you do not transplant at the right time, then after 5 years a solid lump of plant roots will remain on the site, bulging out from under the cover of soil. This negatively affects the development of the terrestrial part, because the roots take all the food for themselves. As a result, irises will be frail and will not be able to enter full bloom.
Important! Irises should be transplanted every 3–4 years.
Best time to transplant
Irises can be transplanted in different periods of the warm season., and not necessarily after flowering. It is important when carrying out the manipulation to focus on the climatic conditions of the cultivation region.
The best option is to carry out the procedure in the summer, 2 weeks after the leaves fall. Approximately this period falls in July - August (depending on the climate of the region). If you did not have time to transplant the plants at this time, then you can postpone the pick in the fall. In the northern regions, it is necessary to have time to carry out the manipulation as soon as possible so that the vegetation has time to take root in a new place before the cold snap and does not freeze. Here, the optimal period in the fall is September. In the southern regions, gardeners have much more opportunities, i.e. a transplant can be carried out before the end of October.
In the case when the plants begin to hurt and the only solution is to change the place of growth, they can be transplanted at any time, not taking into account the flowering period
If the cooling began abruptly in the fall, then the seedlings can be stored in the cellar, and when spring comes they can be planted in the prepared place.
How to transplant
To plant an iris bush in a new place, you must follow a certain order. To begin with, you should prepare the territory for cultivation. Then, manipulate the extraction of plants from the soil. Divide them into parts. Then disinfect, and proceed with the immediate landing.
Did you know? From irises, essential oil is obtained, which is used in the manufacture of expensive perfumes.
Preparing a new place
Choosing the territory for the landing of males, you should pay attention to such moments:
- lighting - plentiful, light partial shade is acceptable;
- the soil - loose, not retaining moisture, highly nutritious;
- ground water level - no closer than 3 m;
- soil acidity - low or neutral, in the range of 5–7.5 pH.
Previously, the site must be cleaned of plant residues and prepared. This stage begins about a month before landing. Dig the soil to a depth of 30 cm. Disinfect with a 1% solution of copper sulfate (1 liter per m²). After 5 days, 10 kg of humus, 1 tbsp. wood ash and 5 kg of sand.
It is better to dig bushes from the soil with the help of garden pitchforks. Unlike a shovel, this tool will do much less damage to the root system.
Gently pry off the roots, trying to submerge the forks deeper in the ground. Then push in the direction of the plant, and dig it out of the soil.
After removing the bush from the soil, the following series of manipulations should be carried out:
- Free the root from the ground. Rinse under running water.
- Trim damaged, dried and rotten roots, as well as leaves.
- If the rhizome is very long, shorten to 10 cm.
- Trim green leaves to a height of 15 cm.
- Carry out the division according to the number of sprouts. This can be done with a knife or secateurs. It is necessary to divide so that on each part there is at least one year-old root growth and leaves.
- Disinfect the root in a slightly pink solution of potassium permanganate (keep 1 hour). Powder all sections on the ground part with wood ash.
- Dry seedlings outdoors for 3 hours.
- Powder the roots with Kornevin Growth Accelerator.
Step-by-step landing instructions
Step-by-step landing of irises to a new place:
- Dig holes at a distance of 50 cm from each other, with a depth of 1.5 times the root volume.
- Seedlings of seedlings in the recesses, placing them in the center. Carefully distribute the roots along the perimeter of the holes flush with the soil level.
- Compact the soil around the plant by hand.
- Water the flowers - for each spend 0.5 liters of water.
- After absorbing moisture, mulch the wells with peat.
Kasatik gained wide popularity not only due to beautiful flowering, but also due to its unpretentiousness in care. If you managed to divide and plant bushes in the middle of summer or spring, then they can bloom already this season.
The main agricultural activities that will be required for irises:
- loosening the soil;
- pruning of faded buds and pedicels, and in the fall dead foliage.
Watering and feeding
Irises need to be watered only in extreme heat and at the time of flowering. In other periods, plants feed on moisture accumulated in the roots. Water is poured under the root when watering. Each flower requires up to 0.5 liters of fluid.
Important! After each irrigation and rain, surface loosening of the soil should be carried out. This should be done very carefully so as not to damage the roots located in the upper layer of soil.
Fertilizers, only transplanted vegetation does not need.
Shelter for the winter
Irises do not need additional warming. They are a hardy crop. The only exception is Siberia. In this region, it will only be necessary to cover plantings with fallen leaves or spruce branches.
Timely transplantation of irises helps reduce the risk of contracting diseases and pests. Gardeners who comply with this rule practically do not face infection of vegetation with harmful bacteria. If a pest such as aphid appears, it is necessary to treat the flowers with Actellic according to the instructions. If there is an invasion of slugs, then they are fought by dusting leaves and soil with tobacco dust.
Did you know? In America, it is customary to give a bouquet of irises for a birthday to people born in February and for the twenty-fifth wedding anniversary, i.e., for a silver anniversary.
The main problems that can be encountered during the cultivation of males:
- Yellow or brown spots on foliage - caused by waterlogging of the soil. The first step is to remove the affected parts of the plants. Powder the slices with wood ash, and add a mixture of dry peat with sand to the bed (1: 1). For prevention, in the beginning of spring, they are treated with 1% solution of copper sulfate.
- Scanty, sluggish flowering - provoked by a lack of light or high acidity. If the second reason is relevant, then correcting the situation will help to add wood ash to the garden - 1 tbsp. for each m².
- The appearance of wrinkles on the foliage - caused by adverse weather conditions. In this case, no action should be taken. This will not harm the plants.
- Flowering delay - It can be triggered by a defeat by pests, insufficient watering in the dry period, freezing of flower buds, depletion of the soil, or root proliferation.
In order for the garden where irises are planted to always delight the eye with bright colors of flowering plants, they must be planted in time and properly maintained. The best time for dividing the bushes is summer. However, if for some reason the gardener did not manage to do this, then you can carry out the procedure in the fall or spring, focusing on the weather conditions of the cultivation region.
