One of the first descriptions of Irgi round-leaved was made by the German botanist Jacob Sturm in his book "Deutschlands Flora in Abbildungen" in 1796. In the wild, this plant of the apple family is found in Central and Southern Europe, in the Crimea and the Caucasus, and even in North Africa.

In Europe, irga is more often used to create hedges, and in Russia - as a fruit shrub.

Advice! Irgi berries are very useful for people with vision problems.

Reproduction of round-leaved irgi

It is not difficult to propagate round-leaved irga. This can be done in all ways traditional for shrubs:

  • root processes;
  • layering;
  • cuttings;
  • seeds.

Powerful root shoots give many shoots. By cutting off the shoot with part of the root, you can get excellent planting material. Layers are easy to make on your own by bending the shoot to the ground and digging it in. You can also use the traditional method of propagation for bushes - cuttings.

Seed planting is not the fastest way. Nevertheless, the planted seeds germinate excellently and give an increase of 10-15 cm per year.

Planting and caring for round-leaved irga

When planting, it must be borne in mind that the round-leaved irga will grow into a tall, spreading tree and create a large shadow. It is also worth considering that powerful roots and falling berries will constantly produce a large amount of root growth, and if you do not remove it in time, the shrub will create real thickets in a few years.

Site selection and preparation

Irga round-leaved is a very unpretentious shrub. It grows well on all types of soil, and even on rock, making its way into cracks with its roots. Only heavily swampy and heavily shaded areas should be avoided. To obtain a good harvest, it is better to choose loamy or sandy loam soils with a neutral acidity index.

Important! Many gardeners plant this type of berry shrub on the northern side of the site as a hedge to protect it from the piercing, cold winds.

How to choose seedlings

For planting round-leaved irgi, seedlings of the second year of life are chosen. By this time, they should have a well-developed root system and reach a height of 35–40 cm. Low seedlings are best left for growing.

Planting procedure for round-leaved irgi

Before planting, the soil is dug up with the simultaneous introduction of organic matter (usually considered 10 kg / m²), adding also two tbsp. tablespoons of superphosphate and one tbsp. a spoonful of potassium sulfate. The pit for planting should be at least 60x60 cm in size. When planting, you need to deepen the root collar of the irgi seedling by 5-6 cm. Shoots after planting are cut into 4-5 buds.

Mass planting of irgi is carried out according to the scheme of 2.5x2.5 m. When planting in a row to create a hedge, the distance is reduced to 1 m. On production plantations, the distance between the rows is increased to 4 - 4.5 meters for the passage of equipment. Saplings of round-leaved irgi usually have a very good survival rate, and the planting procedure does not cause difficulties.

Interesting! This culture is called nothing less than a "garden filter" because it not only purifies the air, but also, like a sponge, absorbs harmful substances from soil and water.

Irga Round-leaved care

Irga round-leaved is an extremely unpretentious shrub. Caring for him in the first years of life is similar to caring for currants. Care includes pruning, watering, fertilizing and digging up the soil.

Watering

Watering is needed only during the fruiting period, although it will never be superfluous - this plant is not afraid of excess moisture. Lack of water will lead to crushing of the fruit and their premature shedding.

Weeding and loosening the soil

During weeding of round-leaved irgi, it is necessary to simultaneously remove the root shoots, which in excess forms a bush. The roots of the shrub are shallow, so loosening the soil helps to increase the flow of air to them and enhance the growth of the plant.

Top dressing of round-leaved irgi during the season

Top dressing of round-leaved irgi is done in the first years to accelerate growth and in the future - to get a good harvest. It is produced in several stages.

Terms of introduction

Feeding rates

Spring (before the leaves bloom)

Nitrofoska 30 g per 1 sq. m

Summer (June)

Urea 40 g per 10 l of water, infusion of mullein 0.5 l per 10 l of water

Autumn (after falling leaves)

Superphosphate 200 g, potassium sulfate 20 g, wood ash 300 g

Important! There is no need to apply nitrogen fertilizers in the fall, this stimulates the development of root shoots.

Pruning: terms and rules

Pruning fruit bushes is a must. It allows you to:

  • form a bush;
  • rejuvenate planting;
  • remove diseased, broken branches.

Pruning can be done either in the spring, before the buds swell, or in the fall, after the leaves have fallen off. Until the age of three years, pruning is not performed, and in subsequent years, three of the strongest shoots are preserved annually. In total, the bush is formed from 15 trunks of different ages.

In the first year after planting, all vertically growing shoots are cut by a quarter. In subsequent years, the shrub is either thinned out or shortened. When thinning, excess vertical shoots are removed, as well as branches that grow inside the crown. This pruning is used to increase yields.

If the plant plays the role of a hedge, then, on the contrary, it is compacted, cutting off the shoots to a bud, which grows inside the bush.

Preparing round-leaved irgi for winter

Irga round-leaved has good winter hardiness. No special events are held in order to prepare it for winter. It is enough to clean the foliage, carry out sanitary pruning, dig up the tree-trunk circle, and apply autumn feeding.

Important! Shoots older than six years old can be cut at the root, they will quickly be replaced by new, more powerful ones.

Irga oval has good immunity to diseases. Pests also hardly touch her. The main diseases of irgi are shown in the table.

Name of the disease

Signs of appearance

Planting and caring for a round-leaved irga will not cause difficulties even for a novice gardener.
