Irga spikelet has quite a few advantages over other garden shrubs. These include:

  • undemanding to the place of growth;
  • good productivity;
  • great fruit taste;
  • versatility of the use of berries;
  • shrub can be used as an ornamental or berry.

Irgi berries are consumed both fresh and processed. They can be used to make compotes, preserves, in North America they are used as raw materials for the production of fruit wines. Due to the content of vitamins of group B, C, PP and other microelements, the fruits can also be used for medicinal purposes.

Reproduction of spiky irgi

Since the spicata is a shrub, it can be propagated in all ways typical for this type of plant. These include the following breeding options:

  • seeds;
  • cuttings;
  • layering;
  • planting root shoots;
  • dividing the bush.

In the process of growth, the shrub gives rise to numerous root shoots, therefore reproduction by planting root shoots is the least laborious method.

For propagation by seeds, you need to select large ripe berries. Seeds are planted in a nutritious soil under a film. The growth of seedlings in the first year can be up to 15 cm. When propagating by cuttings, young healthy shoots 30–35 cm long are used. They are kept in a root growth stimulator, and then they are also planted in the soil under a film.

Important! When propagated by seeds, all the varietal qualities of the plant are lost, only species characteristics remain.

For propagation by layering, the extreme shoots are bent to the ground, fixed with brackets and covered with soil. This place is intensively watered for one and a half to two months, which leads to the formation of new shoots. After that, they are cut off from the mother bush and transplanted to a permanent place.

Dividing a bush is the most time consuming method. It is done when transplanting an entire plant no older than 7 years. In this case, the bush is completely dug out of the ground, part of its roots, along with shoots, are cut off and transplanted to a new place.

Planting spicata

Planting of spicata can be carried out both for decorative purposes and to obtain a harvest of berries. Plants are often planted in a row to create a so-called "hedge" to protect the site from the cold wind.

Site selection and preparation

Irga spikelet is extremely undemanding to the type and composition of the soil. Avoid only very wetlands with a groundwater level above 2 m. A strong shadow will not lead to the death of the plant, but the shoots will become very thinner, and the crop will not grow very plentiful. A good option would be to plant a spiky irgi along the border of the site on the north side.

When is it better to plant spike irga: in spring or autumn

Since the spikelet has excellent rooting ability and excellent winter hardiness, the season is not decisive. Autumn is considered a more favorable time.

How to choose seedlings

You can plant a seedling of the first or second year of life in a permanent place. It is better to choose seedlings with closed roots. If the roots are open, there should be no rot on them.

How to plant an irga spikelet

It is possible to plant a spiky irga in a row, in a checkerboard or dotted manner. For planting, you need to dig a hole with a depth of at least half a meter and a diameter exceeding the size of the roots. For good rooting, a mixture of sod land and humus is poured onto the bottom, adding 50 grams to it. superphosphate and 20 gr. potassium sulfate. The root collar is buried 4-5 cm.

The pit with the seedling is covered with turf soil, spilled with several buckets of water and mulched with peat.

The distance between neighboring bushes is made at least 2.5 meters. When landing in a row, it can be reduced to 1.5 meters.

Spike irga care

Irga spikelet does not require special care. If the shrub is planted for decorative purposes, you need to take measures to form the crown - pruning and cutting. To increase yields, you need to do not only pruning, but also top dressing.

Watering

Irga spikelet belongs to drought-resistant shrubs and does not need watering. It is advisable to produce it only during dry periods and during the setting and ripening of fruits.

Weeding and loosening the soil

Weeding of spicata is usually carried out regularly, together with the removal of root shoots. At the same time, loosening of the soil is done. A complete digging of the trunk circle is carried out in the fall, combining this with the application of fertilizers.

Top dressing of spicata during the season

Irga spiky does not need feeding if planted in good soil. If the soil is poor, you can feed the bushes several times per season:

  1. In the spring, in the period before the beginning of leaf blooming - any nitrogen fertilizer, for example, nitrophosphate, 30 g per 1 sq. m;
  2. In summer, during fruit setting - infusion of mullein or bird droppings 0.5 l, or urea 30-40 g per bucket of water;
  3. Autumn, after leaf fall - wood ash 300 g, superphosphate 200 g, potassium sulfate 20 g per 1 sq. m are introduced into the near-trunk circle in the process of digging.

Important! For optimal fruiting, it is advisable to feed the plants with humus once every three years, bringing it in in the fall at the rate of 30 kg per one bush.

Pruning

Pruning of spicata should be done regularly. It has several goals:

  • crown formation;
  • thinning;
  • removal of sick, broken, dry branches;
  • rejuvenation of the bush.

The formation of the crown allows you to compact the bush and make it more compact. It is used when planting irgi in a hedge. Thinning is done annually after the third year of life. For this, 3 strong annual shoots are left, the rest are cut out. In total, the bush is formed from 15 branches of different ages.

Sanitary pruning should be done in the spring before the leaves begin to bloom and in the fall after they fall. Rejuvenating pruning is the complete removal of shoots over 6 years old. They will quickly be replaced by the young.

Preparing spiky irgi for winter

Irga spikelet is distinguished by excellent winter hardiness and calmly withstands cold temperatures of -40 degrees and below. Therefore, no special measures are taken to prepare the shrub for winter. You can limit yourself only to sanitary measures, pruning and cleaning of fallen leaves.

Disease / PestWhat amazesTreatment and prevention
PhallistikosisLeaves, covered with brown specks and die offInfected foliage must be torn off and burned, the plant must be treated before and after flowering with copper sulfate or Bordeaux liquid
Septoria (gray rot)Leaves, fruits become covered with gray fleecy spots and rotReducing watering or replanting to a drier place; treatment with Oxyhom, Topaz or Bordeaux mixture
Tuberculariosis (drying of branches)The leaf plate and the ends of the shoots turn brown and dryCut and burn the shoots. In the spring, before the leaves bloom, treat the bushes with copper sulfate or Bordeaux liquid
Irish speckled mothLeaves from moth secretions begin to crumble and dry out.Spraying with preparations Fufanon, Karbofos
Irrigated seed-eaterFruits, the larva eats the seeds and pupates in the berry

Important! Blackbirds pecking berries can become a real disaster for irgi. To protect against them, special nets are used.

I planted the spikelet irga myself twenty years ago. I don’t fertilize it, I don’t spray it, I only cut out old branches in spring and cut down young growth with a shovel. The most reliable shrub, there are always berries on it. And what a beauty in spring!

Antonina Sergeevna Maretskaya, 53 years old, Saratov

A spike-headed irga has been growing in my garden for a long time. And it blooms beautifully, and there are a lot of berries from it, I put them all on the compote. When the berries appear, I cover the bushes with a net, otherwise the birds will harvest the crop before me.

Elena Petrova, 31 years old, Balashikha

We bought the garden recently, and the spikelet irga was already growing there. My husband wanted to cut down the bushes, but I persuaded to wait until autumn. And the Irga thanked us, but with such a harvest that her husband now almost blows away dust particles from her. We want to plant a couple more bushes in the fall.
