Above the ground remains a trunk about xNUMX cm long with healthy kidneys 10-4.

How to plant irgu in spring
Peculiarities of planting irgi and care in the Moscow region correspond to the general recommendations for planting and caring for trees in general. To plant seedlings of this shrub is desirable in the autumn. According to some experts, this can be done in March, when there will be favorable weather conditions.
It is necessary to make pruning of weak branches in time. In general, on one trunk should not be more 2-3 healthy shoots. In 3, the shrub should have about 15 branches. Older plants can be periodically rejuvenated.
Planting shadberry and features of care, see the photo below, which shows the annual method of dealing with the growth of this shrub:
Young shoots, or as they are also called "zero", need to be removed not above the ground, but near the root of the plant, except for those from which the shrub is subsequently formed or with the help of which its rejuvenation is subsequently carried out.
How to grow irgu from seeds

It is possible to propagate shrubs with seedlings that can be purchased or grown from seeds. Seeds are planted in fertilized beds and then well watered. When the seedlings reach the 1-2 age, they are planted in a permanent place.
Cultivation of irgi does not require special skills, the main thing is that the plant should be taken when planted, further care is to feed, form the crown, prune weak, old or dry branches, thinning the bush.
If you are interested in how to plant an irgu from seeds, you need to know how to properly prepare them for planting. For the preparation of seed material, ripe fruits are taken, rubbed and rinsed with cool water. Bad seeds usually float to the surface. The washing procedure should be carried out until the good ones remain at the bottom.
You need to know how to plant irgu correctly, using seeds if you have chosen this breeding method. In the groove length of one meter to sow about 300 seeds to a depth of 1,5-2, see. Sowing is done in early spring, sometimes at the end of winter, and the ascent of descents can be expected for almost a year.
How to grow irgu, when the seeds have germinated, every gardener should know. Paroski, in which 3-5 grows full-fledged leaves, decompose and grow to 1-2-year-old. For the bushes grown from seeds, homogeneity is characteristic. Presumably this is caused by the asexual method of reproduction (apomixis).
Reproduction of irgi cuttings and root processes
The easiest way to breed irgi is to use for planting seedlings from the roots, which have to be harvested every year. This bush requires space for the life of 2,5-4 m, between future shrubs leave 1,5-2 m. In nurseries, seedlings are planted in a checkerboard pattern.
The work consists in the selection of suitable basal shoots, the diameter of which should not be less than 0,5 cm, and the length of 10-15 cm. It is important that the roots are healthy and well developed. Prikopanny steam trays are well watered, so that the humidity is constantly at a high level.
For this breeding method, processes that are no more than 6 years old are suitable. It is suitable for amateur gardeners who are interested in planting irgu in the spring by dividing the bushes, because there are no more 4-6 full cuttings. In nurseries, preference is given to seed multiplication in order to obtain a greater number of seedlings.
The propagation of irgi cuttings consists in choosing branches that are no more than one year old and whose length is 12-15, see. You need to prepare a special greenhouse with a special ground mixture. The bottom is covered with a layer of pebbles (30-40 cm), then a mixture of light soil with humus is poured (25 cm), the top is covered with sand (4-5 cm).
Planted and well watered cuttings covered with a film before the roots. This usually happens around 25 days, depending on the variety. To speed up the appearance of the roots on the cuttings, they are treated with special solutions. Rooted cuttings are planted in open ground for next year.

The nutritional composition should be liquid, prepared from ammonium nitrate, 50 g of which is used for one bush or 5 l 10% emulsion of bird droppings. It is necessary to produce top dressing at night, when abundant watering has been carried out or rain has passed.
How to trim irgu in spring
In order not to harm the bush, you need to familiarize yourself with the information on how to trim the irgu in the spring. The shape of the crown can begin with the 3-4 age.

Consider further how to properly trim the irgu to rejuvenate it. Rejuvenating pruning is done when the shrub turns 8-10 years. The need to rejuvenate shows the condition of the bush, such as:
- a small increase for the year (no more than 10 cm);
- increased bush density;
- the appearance of weak and dry twigs.
If you do not do rejuvenation, the bush begins to lose its decorative effect, worse fructifying and being exposed to pests. How to trim irgu to rejuvenate the bush:
- thinning (remove all unnecessary, weak shoots);
- pruning too elongated branches;
- shortening long healthy shoots.
As a result, there should be no more than 10-15 strong branches. Place cut cut garden pitch.
Each amateur gardener, using basic information, will know how to care for an irga correctly, what needs to be done at each "age" period of the plant, what actions to take at a different time of the year. With careful care, it can grow safely and bear fruit up to 70 years.
