Cultivation rules of Canadian shadberry: characteristics of planting and care


Irga is not only a berry, but also a beautiful decorative culture, especially Canadian irga. In spring, its leaves are green, and with the arrival of autumn they turn yellow and even turn red. Changes color and berry: at the beginning of ripening it is pink, then red, and at the end - almost black. No less gorgeous shrub and during flowering, when the shoots are covered with small white inflorescences. This happens at the end of April - in the month of May, so the buds are not afraid of frosts. Even in winter, an irga will decorate the plot, standing out against the background of snow with its brownish shoots.

Characteristic view

Under natural conditions, the common irga is most common, growing quite a tall tree or a lush tall bush. Among gardeners, Canadian irga is more popular. It has a more compact size, large berries and high yield. In addition, this species has an increased resistance to drought and low temperatures, which allows it to be grown in regions with a cold climate. Another nice bonus is that Canadian irgua are not so much eaten by birds, and in fact they love it very much and often deprive half of the crop.

To scare away birds, you can hang rain on the branches, which decorate the Christmas tree, or something rustling and shining.

Irga grows in the form of a lush bush that forms up to 20 trunks. Depending on the variety, their height can be 2 or 6 m with a diameter of a spreading crown and from 2.5 to 5 m. However, it is easy to adjust the height of the irgi in height by trimming. It grows quickly, the annual growth, both in height and in width, is up to 40 cm. The shrub forms no less rapidly, especially if the soil is poor.

Irga fruit regularly, annually, abundantly and regularly. Experienced gardeners who grow this shrub, note that the ovary may not be no more than 1 year out of 10. The first harvest can be taken as early as 3 years after planting. The berries are large, sweet, ripen in mid-July, but not evenly, stretching the harvest period until August.

Canadian Irga: species description and popular varieties

Irga canadian - deciduous multi-stemmed plant of the Rosaceae family (Rosaceae). The height of the shrub ranges from 3 to 8 meters. The tree has strongly branched roots, placed close to the ground surface. The young bush has an elongated loose crown, the shape of which expands with time and becomes umbrella-shaped. Only 40 years later the tree will reach 6 m in height and 7-8 m in width.

The leaf of the plant is petiolate, elliptical or oblong-ovoid, pointed at the end, pointed at the edge. The upper surface of the leaf is dark green in color, the reverse side is pale green. In the blooming phase, the leaf takes on a copper-red hue, and in the fall it becomes orange-yellow or red. Numerous flowers are collected in rare vertical clusters, placed along the entire length of the shoots. The flowers are bisexual, five-petalled (star-shaped), odorless, white or cream-colored. The period of flowering culture falls on April and May. Fruits ripen unevenly in early July.

Small berries have a rounded shape, resembling a small apple. The skin of the berries is very tender, and the flesh is sweet and juicy. The color of the berries is reddish purple or bluish black.

Habitat - North America, the peninsula of Crimea, the Caucasus. On the basis of the Canadian shadberry many varieties were created. Consider the most popular ones.

  • "Slate" - early culture with large black berries. Fruits with high sugar content have a great aroma, taste and juiciness.
  • "Mandam" - Mid-season shrub, reaching up to 3 meters in height. The plant gives a big crop even in adverse years. Fruits are large, sour.
  • "Ballerina" - deciduous tall (up to 6 m) tree. Long branches with age hang down to the ground. The fruits are juicy and sweet. The variety grows well in urban environments. In the berries do not accumulate harmful components from gassy air.
  • "Krasnoyarsk" - late-ripening variety, the berries of which are ready to be harvested in the middle of summer. The fruits are especially large, sweet and sour. The variety brings a great harvest and is adapted for cultivation in the harsh climatic conditions of the Central Belt and the North-West. The plant shows excellent winter hardiness.

Soil requirements

In search of nutrients, the roots of the Canadian shadberry grow wildly, releasing root growth to the surface. Therefore, the plant is best grown in sandy soils and fertile loams. The ideal soil mixture: turf ground (2 parts), sand (1 part), peat (1 part). Irga grows equally well on soils with different acidity.

Landing pit preparation

The tree is usually planted in a small landing pit with drainage. Dig a groove with sides of 6 cm and a depth of 5 cm. The landing site must be cleared of weeds, dug up and kept under steam. 7-8 days before planting, lay a small layer of potash and phosphate fertilizers on the bottom of the landing pit, or add a mixture of humus (bucket), phosphate (500 g) and a little lime. Stir and tamp the mixture thoroughly. After a while the soil is again digged.

Landing pattern

The technology of planting a bush will not cause difficulties even for a novice gardener. The process of planting is not significantly different from the landing of any other fruit culture.

Tree planting scheme:

  1. The prepared soil mixture is transferred to the planting pit.
  2. In the center of the pit form a cone, at the top of which establish a sapling. The roots of the seedling spread on the slopes of the cone.
  3. Then the pit is covered with the rest of the soil.
  4. Landing plentifully irrigate 10-15 liters of water. Over time, the soil in the area will shed a little, so the soil will need to be trimmed.
  5. To ensure optimal growth conditions of the tree, the soil around the irgi needs to be mulched. For this purpose, use dry land, peat or dried humus.

Plant Care Basics

Irga Canadian unpretentious care. Shrub resistant to frost, drought, wind and waterlogging. This culture does not require regular watering and feeding. Only in the third year after planting, every six months the soil begins to be fed: long-acting nitrogen fertilizers are introduced in the spring, and phosphate-potassium fertilizers in the autumn.

Before winter, when the movement of nutrients along the trunk of a tree slows down, irguu can be cut off, leave only 15 cm from the ground, and the rest is cut off.


Canadian shadberry propagation is propagated by cuttings, seeds, and root suckers. The most successful method is reproduction by cuttings.

  • Reproduction by seeds. Seeds are washed several times with cold water until only high-quality dishes remain on the bottom. They are sown at the beginning of autumn, 2 g per 1 meter of the plot. Sown seeds will germinate next spring or a year later.
  • Reproduction of root suckers. To begin with, seedlings with well developed roots are selected. Plants are dug up with roots. Reproduction is carried out by tearing off the siblings from the maternal root. Planting seedlings must be strictly vertically.
  • Irrigation cuttings are held in summer. After cutting the seedlings are planted in a greenhouse, watered abundantly and covered with polyethylene. In conditions of sufficient air humidity, after 20 days they will take root. Rooted seedlings for the next year can be transplanted into open soil.

Pests and diseases

Canadian irga is rarely affected by diseases and pests. Of the pests, the most often occurs is the leaf-shaker and the fruit cap moth. Treating Karbofos, Fufanon or Aktellik helps in the fight against these pests. However, usually the pests do not cause particular harm to the shrub.

Summing up, we note that not everywhere has this culture received due attention. However, once seeing this shrub in bloom and having tasted its tasty and healthy fruits, you will certainly wish to plant it in your garden.


Canadian irga begins to bloom in the last decade of April - early May; this process lasts from 10 to 15 days. The flowers of the plant can tolerate frosts to minus seven degrees, which are often in spring.

Irga is very light-loving plant, because of what a dense planting is not recommended, in this case the shrub is strongly drawn upwards and does not bear fruit well. The shrub tolerates dry periods well and is not picky about soil quality.

Irga grows very fast, already by the third year after the planting of the shrub, the first crop of berries appears, and by the ten years of its life the plant begins a time of maximum productivity. The period of productivity lasts from 20 to 30 years, and the average yield reaches from eight to ten kilograms of berries from one bush.

One of the advantages of Canadian shadberry is early and rich harvest The advantages can also be attributed to unpretentiousness in cultivation, winter resistance and drought resistance.

Berry benefits

Irgi berries are natural multivitamin means.

  • Vitamins B, C.
  • Pectins.
  • Carotene.
  • Anthocyanins.
  • Trace elements (copper, cobalt, lead).

The fruits of shadberry have a number of medicinal qualities, namely:

  • Avitaminosis and hypervitaminosis are cured.
  • Soothe the nervous system.
  • Improves the elasticity of the walls of blood vessels.
  • Used as a prophylactic against varicose veins and diseases of the heart muscle.
  • Prevent diseases of the gastrointestinal tract and peptic ulcer.
  • Used to treat atherosclerosis.
  • It is used as an antitussive and expectorant for ARVI.
  • Lower high blood pressure and normalize cholesterol levels.

Variety of varieties

Irga has more than 30 species, the most common in Russia are:

  • Pembina. Growing, reaches a height and width of up to five meters. It has a spreading crown. The advantage of the variety is the formation of a relatively small in quantity and volume of the root system.
  • Smokey in height and width reaches about four and a half meters, with a large spreading crown in the form of an open umbrella. This variety has a late flowering period, thus avoiding the death of the ovary in the plant during spring frosts. The berries grow quite large, with a diameter of about 14 millimeters, with a pleasant aroma and sweet taste. It is the Smoky variety that is the sweetest, without the tartness inherent in the fruits of other varieties.
  • Northline is a multi-trunk shrub of medium size. The harvest of berries is large, the diameter of the fruit is about 16 millimeters. The shrub of Northline forms a large, branched root system.
  • Sturgeon - A bush with a large number of trunks grows in height to three meters. It is one of the most fruit-bearing varieties of irgi, due to the fact that it has long brushes.

What other varieties of irgi are?

  • Thyssen. This variety grows to five meters in height with a very spreading crown. Thyssen is the earliest and earliest variety of irgi. The size of the berries, having a wonderful set of tastes, on average reaches about 17 millimeters. Berries ripen unevenly, because of what the harvest is stretched over time. Variety endures frosts to minus 30 degrees.
  • Irga Lamarck - This is a very large variety. Shrub, which can be compared with a small tree, reaches a height of up to eight meters, has a rounded crown. Unlike Canadian shadberry, this variety grows much more slowly, the annual growth reaches only 25 centimeters in height. With proper and regular formation of the shrub, you will get a beautiful, exquisite plant, which is often used in landscape design.
  • Quite often in the backyards and in the gardens, one can find an richo irregular and a round iris, which are considered decorative varieties. The berries of these varieties are also eaten and used in the manufacture of medicines, but the fruits are small, and the quality of the berries is low.

How to plant Canadian irgu

On the plot or in the garden, an irgu can be planted on the north side, since numerous trunks will hold the snow and protect from the cold wind. Raspberry, gooseberry and currant bushes are planted near the irga.

Plant this shrub spring or autumn. In the prepared well, a sapling of an irgi is planted deeper by 10 centimeters of its previous growth, this will increase and improve the development of the root system. After planting, the plant is plentifully watered with water in an amount of from 10 to 15 liters. The soil around the seedling is mulched, and the shrub is pruned to a third of its height, leaving a maximum of five well-developed buds.

Plants are planted every three meters, and to create the so-called hedge they use a chess boarding method: every 50 to 70 centimeters in rows and between the rows.

Watering and feeding

Further irgu is necessary water during dry periods, mulch the soil around the plant and feed. The plant is very fond of fertilizer. During the season, it is recommended to feed the shrub every month with various liquid fertilizers of organic origin, for example, infusions from bird droppings or mullein.

Carry foliar feedings microfertilizers and organic additives follows, combining with watering a bush. The result of the correct actions to care for an irga will be a rapid growth and a rich harvest of berries.

How to produce pruning

In order to form a plant in the form of a multi-stemmed bush, in the first years after planting it is necessary to cut off weak shoots and leave two to three strong null shoots growing in the root area. A properly formed shrub of an irgi should consist of 10 to 15 branches, different in their age.

In the period when the annual growth of shoots will not exceed ten centimeters, they begin to exercise anti-aging pruning, which consists in the removal of all highly elongated and weak shoots. The rest of the shoots are cut so that their length does not exceed two and a half meters. Absolutely all large sections are necessarily treated with garden pitch, which is made independently or purchased in specialized stores.

Irgu Canadian for a brighter decorative manifestation form an oval shape, cutting the crown of the shrub. As a result of this type of pruning, new shoots will rapidly develop and grow, giving healthy fruit buds. Irgu Lamarck form a shrub with three or five trunks, and the rest of the shoots are removed throughout the season. The branches themselves are pruned annually, shortening them.

Diseases and pests

Canadian Irga is very resistant to most fungal diseases and pests. Often the shrub is affected currant and rosian leafworm. They destroy the foliage and the end of the young shoots.

During the ripening of the berries, birds cause considerable harm to the irga, preferring to eat the sweet and juicy fruits. In order to avoid loss in yield, young shrubs are covered with a net.

The advantages of shadberry canadian include the fact that the plant is very fruitful and tenacious. Irga will not wither in hot weather and will not freeze in severe frost, so this variety is perfect for planting in Moscow's home gardens and gardens.

Location and landing features

You can plant where it is not convenient to her. and us, whether high groundwater
or low, fertile soil or so-so, is the place open to the north winds.
Condition: for the harvest to be high, it is necessary to plant a tree or a bush in the sun or partial shade, there will be no berries in the shade. Although one of my shrubs, irgi, illuminates only the western sun, I do not complain about the harvest.

A full hole during planting can not dig, the root system is superficial, rarely
reaches half a meter, here in width the roots spread up to two meters.

When you plant, put a glass of complex fertilizer into the hole, or a compost bucket, or just an armful of weeded weeds, pour, grumble, and close the stem of the grass with the grass cut.

The time for planting is spring or autumn, while the bush is shortened by 4-5 buds for better development and formation.

A photo of the Pembina variety - this is how it looks in the spring when it was planted and cropped last fall.

The same sapling a year later.

In our country, Canadian irga is more common. Its height is up to 4.5 meters, tasty fruits of small size. To get larger ones, up to 1.8 centimeters in diameter, others can be grafted onto a Canadian one, cuttings can be ordered from nurseries and grafted onto your tree.

You can buy already grafted saplings, but know that they do not exceed the taste already existing on your irg, and in size ... just water more (but not often), cut out extra branches and root growth.

What care is needed

Irga practically does not require it.

Watering is rare, but abundant. forgot to water - forgive.

Vaccination on a new variety is justified, in my opinion, simply by the interest of a creative person, or by some kind of necessity. For example, if you plant on a Canadian variety of irgi Pembin, a tall beautiful tree will grow, and the Regent grade will be only 1.2 meters high.

How to trim

It must be remembered that irga blooms on the shoots of last year, if you
you will cut the tops, do not expect harvest next year. Here it is necessary to withstand
определённый баланс между молодыми веточками и «пожилыми». Удаляйте каждую осень небольшое количество лишних.
Если образовалось слишком много высокой взрослой поросли, можно вырезать стволы на нужной высоте, тогда образуется боковые побеги, которые прореживают при

Полезные свойства ягод

Вкус их необычен для наших садоводов, он сладкий, но слегка пресноватый. Ягоды так
It is useful that birds prefer irgu to the rest of garden delicacies. You should not get upset about it - there are so many fruits that there is enough for people.

Berry berries (they are also called northern raisins, brown bread) contain phytoncides. fiber, tannins, anthocyanins, trace elements copper, cobalt, iron. There is vitamin C, a lot of vitamins of group B, and also P - active vaso-and heart-strengthening compounds. This alone makes irgu necessary for any person.

There is beta-sitosterol in the fruits, which lowers cholesterol and
coumarins - protection against sclerosis.

Berries reduce pressure, have wound-healing properties.

From the decoction of bark and leaves of cinnamon make lotions for varicose veins and phlebitis. To do this, 100 g of raw material is poured with a glass of boiling water and kept in a thermos for 2 hours.

Eat more irgi in the summer, contraindication - rarely allergies. Reduction same
pressure occurs smoothly, so you just need to reduce the amount of food eaten.

For those who do not want to part with brown bread in the winter, I suggest freezing the northern raisins or drying them in the oven. You can bake a wonderful pie from frozen fruits.

Here is the recipe: Melt 60 grams of margarine, add 100 grams of granulated sugar, 1 egg, half a teaspoon of soda and 4 tablespoons of sour cream or a fermented milk product. Mix everything and add flour so much to make a soft, but not thin batter.

Lay it out in shape, make the sides, and cover the rest of the area with frozen irgi berries. For sharpness add sliced ​​Antonov apples, or raspberries, even cottage cheese, how much fantasy is enough. Bake 40 minutes or less at 220 degrees. See photos: delicious, I advise!

Irgi varieties - descriptions of the best large-fruited varieties of Canadian irgi

Canadian varieties stand out from the variety of varieties of shadberry and, first of all, by their large size, yield, color of the flesh of ripe berries, timing of flowering and ripening. It is with these qualities that they deserve their popularity. Nowadays, about 80 varieties of irgi are known (for more information on the selection of irgi here).

There are widespread varieties that are grown in all areas where crops and crops are cultivated, which are much less common. It does not always mean that they are worse. Some of them have been obtained relatively recently and are still undergoing trial testing. For another part, the nursery specialists could not choose a breeding technology approach - and it is difficult to purchase seedlings of these varieties. It should be noted that the irga multiplies not so easy (separately about the breeding of irgi here).

In compiling the description of varieties of rygi, we proceeded from the following premises:

To the list of varieties

Irga is spiky and round-leaved, of the Pink family, known in Europe since the 16th century. In landscape design are used as a blooming decorative culture and for hedges. We tell in the article about the cultivation of shadberry and reproduction in different ways, give tips on caring for shrubs.

Gardeners of the middle band successfully grow irgu for healthy fruits, which contain many vitamins and nutrients. A self-bearing shrub, 2 - 2.5 m high at the age of 10 years, yields up to 15 kg. Differs in extremely unpretentiousness, but on rich soils quality of berries is much higher. Popular simplicity of reproduction - seeds, cuttings, dividing the bush.

Planting seedlings in a permanent place

Next spring, grown seedlings can be planted in a permanent place. Irga has a strong root system, therefore the place for a bush is stipulated taking into account its maximum dimensions: crown diameter is 3 m, root depth is 2 - 2.5 m. On this basis, the conditions should be as follows:

Table number 1. Conditions for landing irgi on a permanent place.

Irga is prone to the growth of root shoots in search of nutrients. On loose, rich soils, the shrub is localized. Responsive to organic fertilizers. The quality of the fruit depends on the fertility of the soil. The soil mixture consists of light loam, coarse-grained river sand, rotten compost in a ratio of 3: 1: 1. 150 grams of potash and 400 grams of phosphate fertilizers and 1 bucket of humus are added to each pit.

When planting, the seedlings are not buried, and after the land settles, they mulch with dry humus, low peat, mowed grass. After planting, the shoots are shortened, leaving 4 - 5 buds, to balance the root system with the ground. ".

Tip # 1. Do not land irgu near open parking lots. The fallen berries leave not washed marks on cars.

Dates of breeding green cuttings

In order to preserve the varietal characteristics of the irgi, it is best to propagate it vegetatively, for example, with green cuttings in June. For the middle band, you can use the 5 best varieties Irgi:

  1. Material length of 10 - 15 cm, taken from the five-year bushes, cutting from the tops of the shoots.
  2. On the cuttings leave the top two leaves, all others are removed.
  3. The lower sections are kept in the solution of the rodent for 6 - 12 hours. You can powder the stalk in powder form just before planting. Usually, the “Conqueror”, “Kornevin”, “Heteroauxin”, “Rizopon” are used.
  4. Prepare the sandy mixture in the garden in an open field or cold greenhouse.
  5. Planted cuttings at a distance of 4 - 5 cm. It is desirable that the leaves do not come into contact with each other.
  6. Landing sprinkled with 10 cm of a layer of sand. Watered to a depth of 5 cm.
  7. Arrange a greenhouse height of 15 - 20 cm.

Greenhouse for cuttings of irgi can be made with your own hands

  • Maintain a temperature of 250, airing a greenhouse if necessary, otherwise, in hot weather, the cuttings will “weld”. After two, three weeks, the planting will take root, then the cover will be removed for the whole day, and eventually will be removed completely.
  • Then the cuttings are seated for rearing. When they adapt to the new location, you can enter the dressing with a slurry solution of 1: 8. Further care of the plant is the same as for the seedlings.
  • Inoculation varietal cuttings

    From the seeds of the species irgi you can grow a stock for grafting. For this purpose, well suited two-year-old rowan seedlings. The basis may be the root growth of these crops. Vaccination is carried out in the spring, when active sap flow begins. ".

    1. The stock (grows in the ground) is cut at a height of 10 - 15 cm.
    2. Form the graft:
    • choose lignified shoot, up to 1 cm in diameter,
    • the top is removed with an oblique cut,
    • the lower part of the cutting is cut under the kidney on the wedge 4 cm
    1. On the stock with a garden sharp knife make a vertical incision in the middle of the shoot.
    2. Insert a wedge into the rift so that the cut of the graft coincides with the stock on the bark.
    3. Press tightly and wrap with electrical tape. Recently, it began to replace food film, tape or special strips for vaccinations.
    4. The vaccination is covered to preserve moisture and temperature.

    Inoculation irgi cuttings

    Approximately in a month it will be seen whether the vaccination has taken root. This can be determined by new leaves that appear from the kidney graft. If a stock grows undergrowth, it needs to be urgently removed, otherwise the graft is threatened with rebirth and instead of a varietal shadberry you will get a species one.

    Rules for transferring bushes to a new place

    Sometimes the original place for an irgi is chosen poorly, expanding, it takes up much more space than expected. Perhaps there were other reasons why it should be transplanted. It is easier to tolerate this procedure shrubs up to the age of five, more adult plants take root worse.

    To Irga rooted in a new place to dig it to be lumped. The older the bush, the more com. Manually you can move the root system with the soil 50 x 50 x 50 cm. For coma with a diameter of 1 m requires special equipment.

    Irga grows in light ground, in order to preserve it during transportation, you need to tightly wrap the roots along with the ground on the sides and tightly tie them up. Place a flat support under the bottom of the coma, for example a sheet of plywood, and lift the bush along with it. In this form, transferred to the landing site and lowered into the prepared pit. Carefully release the clod from the substrate and the winding. fall asleep roots, as during normal planting.

    Water plentifully to moisten a lump and a soil around it. The amount of water such as the volume of the landing pit.

    Pruning shrubs to improve yield

    Irga is an unpretentious plant and can adapt in any conditions. But, if we are talking about the harvest, you need to take care of it. The bush grows thickly without supervision, the leaves take away the nutrients from the fruits and the berries become small and not sweet. To improve the quality of the crop, prunes are cut like any other garden shrub. ".

    • In the autumn they carry out sanitary pruning, completely remove dry, old, diseased and broken branches. Cuts with a diameter of more than 1 cm are covered with garden pitch or special paint against pathogens and pests.
    • Spring shorten or cut off shoots that grow inside the bush. Adjust height for convenient fruit picking. In general, they are formed in such a way that all branches are illuminated evenly and do not shade each other.

    Major pests irgi

    1. Scraped, so called variety of the leaf-bearing moth, which is dangerous for Irga. Caterpillars so strongly gnaw leaves and shoots that the bush looks like peeled. Pests are activated in the spring with the onset of sustained heat. In a short period, until they turn into a pupa, they manage to cause considerable damage to the shrub.
    2. Another pest - the moth winter, differs in later periods of development.
    3. A threat to Irga, as well as for the whole family of Pink (aka Rosaceae), is represented by leafworms. One of them is rosana. Damages the leaves, turning them into a tube. A weakened plant gives a modest and not tasty harvest.

    Types and varieties of irgi

    Rosaceous Leaf Caterpillar

  • If Irga grows next to an apple orchard, an apple louse can move over it. True, this happens very rarely, but causes a lot of trouble. Larvae parasitize on fresh young shoots, feeding on plant sap. Their lifespan is only 15 days, but in one summer they give up to 8 generations. It is important to take precautions in time.
  • Table number 2. Means of pest control.

    Chemical insecticides Binom, Atom, Bi-58, Di-68 New, Rogor-S, Desant, Teldor, Zagor and others are used to control pests. Bacteriological preparations that are safe for humans and plants are represented by Akarin, Lepidotsil, Bitoksibatsillin, Fitoverm.

    Tip # 3. You can get rid of aphids with the help of the sticky belt Bros.

    Errors when growing irgi

    Error number 1. Not observing the desired interval during landing.

    Irga grows quickly and densely. If between bushes do not leave 4 m initially, they will intertwine with each other and over time they will have to be transplanted.

    Error number 2. Neglect pruning.

    Unregulated growth leads to a predominance of leaves to the detriment of the crop.

    Error number 3. Landing in the shade.

    Irga plant is unpretentious, will adapt to any conditions, but if the goal is a harvest, then you need to plant bushes in the sun. In the shade, irgu is grown for decorative purposes.

    Question number 1. I planted irgu in the far corner of the garden, I am not in the country every week. During my absence there was a mass of overgrown around the bush. Why? And what to do with it.

    Your irga grows on poor soil, and that has grown in search of food. If you do not plan to expand the plantation, dig up the shoots, and fertilize the bush with organic matter and grumble so that the moisture evaporates less, and with it the feeding.

    Question number 2. I heard that irgu is planted in hedges. Is it so?

    Exactly. Irga grows as a free, flowering hedge, and sheared. In the shade and in the sun, on fertile soils and on the poor. Not a bush, but a gardener's dream.

    Question number 3. Does the site need two snow huts for pollination, like sea buckthorn?

    No no need. Irga, unlike dioecious sea buckthorn, is a self-bearing plant. Perfectly fruiting alone.

    Question number 4. I heard that the irga is called something else?

    Exactly. She has many names: Pirus, Korinka, Karisha, Korika, Northern Grapes, Baby Berry, Wine Cherry.

    Question number 5. Is it true that it is impossible to plant an irgu near a fruit garden?

    Right. As plants of one botanical family, they have common pests, so if there is an opportunity to better keep the irgu off.

    Irga in the Russian garden: beauty and benefits with minimal care

    No berry can boast such an abundance of names, which in different parts of the world honored the picturesque and enduring irgu. Shady shrub, toffee, honey-bearing, brown bread - not a complete list of the names of this interesting culture. The shrub of the genus Irga from the Rosaceae family, including more than 20 species, is widespread throughout the world.

    North America is considered its birthplace, where it grows everywhere, but the Eurasian continent has long been mastered by it. In Russia, about 10 types of culture are cultivated, the most common of which are Irga Canadian, spiky, blood-red.

    Cultural virtues

    Unpretentious irga accustomed to take care of themselves independently. It is surprisingly winter-hardy, it is well acclimatized on any, except the obviously swampy, soils, it endures any weather conditions - it is not afraid of gale winds, nor exhausting heat, or thunderstorms. Весьма развитая корневая система, способная уходить вглубь на два и более метров, а также горизонтально распространяться на таком же расстоянии от куста, сделала иргу практически неуязвимой.

    It grows quickly, perfectly cuts pruning, is not afraid of shading or gas pollution. In addition, it gives annual yields of delicious and very useful berries, recommended as a prophylactic agent for diseases of the heart, blood vessels and gastrointestinal tract.

    Irga is a long-lived, grows well and bears fruit up to 70 years. The shrub has very powerful shoots. In terms of thickness, they rather belong to trunks, which in a bush can be counted up to 25. If desired, it is not difficult to create a beautiful standard stage tree with the help of formative trimming, choosing the strongest escape.

    Although the bush of this culture is very decorative - it is compact and dense enough. Spreading this culture does not sin, branches depart from the trunks at a very acute angle often parallel to the trunks rush up. In height irga can reach 7-8 meters. Excellent honey plant, it is gorgeous during flowering.

    Landing technique

    Irga - undemanding culture, frost-and drought-resistant, can grow on any soil and combines high decorative qualities with an annual abundant crop, besides, excellent as a hedge. Planted on neutral fertile soils of open sun or slightly shaded areas, the irga gives record yields.

    The technology of planting an irgi, like any berry, begins with the preparation of a seat: when digging into the soil, two buckets of humus are introduced per square meter, standard pits are made up to half a meter deep and wide. Having filled a little more than half of the pit with prepared soil, a 1-2-year-old seedling is positioned obliquely, digging its root neck by 7-10 cm, is covered with earth, compacted and well shed. The shoots are cut to a height of 10 cm, leaving several viable buds on each. Planted at an angle, it will quickly give a strong increase. Irga gets acclimatized perfectly, it can be planted both in spring and in autumn.

    Irgus is often used as a green hedge, in this case, the bushes are distributed in a staggered manner, keeping the interval between plants in rows from 1.0 to 1.8 m and planting them in deep furrows. To simplify the care of the crop, the soil surface under the bushes is mulched with humus.

    Care and reproduction

    Irga successfully bears fruit, even if only one bush grows on the site. Berries begin to ripen from the beginning of July. With a fairly regular watering during the growing season, fruiting irgi is activated, and yields increase significantly. Irga, whose care is reduced to periodic watering and the annual removal of aging trunks and broken branches, is surprisingly resistant to pests and diseases, so she does not need spring treatments.

    She - a kind of culture with the stability of a strong "wilderness."

    The shrub is easily propagated by seed. They are sown on fertilized areas, generously watered. From the shoots appearing in autumn for the next year, quite good one-year seedlings are produced. Often, over-ripe berries falling from the bush into the fertile layer a year later give the same excellent planting material. Almost all varieties of irgi give good growth, capable of breeding with careful transplanting.

    Often gardeners do not spoil irgu pruning, and in vain. The culture usually grows quickly and for more comfortable picking berries the shrub needs to be limited in growth to pruning at a height of up to 2.5 m. It is better to form a plant with a multi-stem shrub from strong root shoots, the weakened branches are completely removed.

    In the first few years, all sprouted strong shoots are left, and from the 3rd-4th year - two or three annually. A competently created bush consists of 10-15 branches of different ages. Subsequently, cutting out an excessive number of branches, weakened, broken and aging branches, gradually replacing them with new shoots. If the growth of the bush has slowed down, a light revitalizing pruning is necessary: ​​once in 4-5 years, all aging trunks are sawed out, changing them to 2-5 years old.

    These are the main stages of caring for this magnificent culture that amazes the whole season: in the spring with wild flowering, in the summer with a scattering of purple and black-gray berries, in the fall with red gold foliage.

    Features landing irgi and further care of her

    Irga is a fruit and berry shrub (small tree), it grows in the wild state on the territory of the Northern Hemisphere. It differs in endurance and frost resistance, thanks to which it has become one of the favorite garden bushes for Russian summer residents. In total, there are up to 25 species of this plant, however, no more than 10 are suitable for planting on the site. Among them I. ordinary, I. Kolosistaya, I. Canadian and some others. Planting irgi and care for it in the future, it is not only the procedure of rooting seedlings. For regular fruiting shrubs need to provide a well-lit place, fertile soil and do not forget about pruning.

    Choosing a place on the site for growing irgi

    Shrub prefers well-lit open areas, but can also grow in the shade of trees with finely dissected leaves (rowan, sea buckthorn). In the shade of deciduous trees, its shoots will be pulled out, and the fruiting will not be so abundant.

    Irrig does not impose special requirements on the soil, but will grow well on sandy or loamy. Perhaps the main requirement is the fertility of the substrate. With a lack of nutrients around the bush will be a lot of root shoots, which periodically have to be cut down. It is not recommended to plant irgu in areas with a high level of groundwater, because the roots go deep into the ground (2–3 meters).

    Irga - planting and caring for her is not difficult, but the preparatory work should begin six months before the purchase of a sapling. Experts advise rooting a sapling in the fall, it is believed that frost-resistant species of fruit and berry crops take root so better, and the next spring will grow faster. The site is dug up in May to a depth of 20 cm, while making phosphate and potash fertilizers, 40 g of the substance per 1 m² is enough.

    Planting Irgie sapling

    Seedlings are purchased in nurseries, the age of plants should be no more than 2 years old, otherwise the percentage of survival rate will drop sharply. When planting several specimens, it is necessary to keep a distance, depending on the type and variety of the plant, it should be from 1 to 1.6 m.

    When growing an irgi, the landing hole is dug up in impressive sizes - 60x60x50 cm, where 50 cm is the depth. The upper layer is laid in one direction, and the bottom in the other. Fertile land (top layer) is used to prepare the substrate:

    • garden land - 3 parts,
    • river sand - 1 part,
    • humus or compost - 1 part,
    • potassium fertilizer - 140 g,
    • phosphate - 350 g

    If necessary, drainage is laid on the bottom of the landing pit. Then, the prepared substrate is partially filled up and a small elevation (hill) is formed from it. So it will be more convenient to straighten the roots of the seedling. Arranging irguu, the pit fall asleep. The main thing is not to sprinkle the root neck with earth. The soil is compacted and watered abundantly (at least 8 liters under each bush). After some time, the earth will settle, and it will be necessary to fill the nutrient substrate to the root collar of the shrub. Only after that the near-stem can be mulched with humus, peat or wood chips.

    After planting irgi, care begins with trimming. The branches are cut to a level of 15–20 cm, leaving at least four healthy buds on each.

    Watering and fertilizing

    The root system of a shrub is well developed, goes to a depth of more than two meters, so irrigation does not need irrigation. The exceptions are only particularly dry periods. In this case, it is recommended to carry out the procedure after 4 pm, when the sun is no longer so active. Experts advise not to water the shrub at the root, but to use a spray nozzle on the hose. So it will be possible not only to moisten the soil, but also to refresh the greens by washing away the dust particles. After watering, it is advisable to weed the weeds and loosen the soil. If mulch is laid on the ridge, then weeding and loosening is not necessary.

    Growing irgi on the plot does not require frequent fertilization. If under digging a sufficient amount of organic matter and minerals were introduced, the first dressing is carried out only when the shrub has reached the age of five. Once per season, the following components are added for digging:

    • humus - 1.5–2 buckets,
    • superphosphate - 280 g,
    • potash fertilizer - 180 g

    When fertilizing, it is necessary to retreat about 25 cm from the root collar. As the shrub grows, dosage should be increased.

    In spring and summer, you can spend another 2 fertilizing organic matter. A well-proven solution of chicken manure in the ratio of 1: 15. The organ needs to be made only after rain or watering in order to protect the roots of the plant from chemical burns.

    Pruning irgi

    Pruning is an integral part of caring for an irga after planting a sapling, however, it is not worthwhile to radically trim the bush. Decorative pruning may be required only for undersized specimens, while large shrubs will become more difficult to trim as they grow. The first procedure is carried out not earlier than one year after landing. The most favorable time is early spring, while the plant is at rest.

    At the first pruning, you need to carefully inspect the shrub and select some of the most powerful stems from the root shoots. They will act as the basis. The rest of the shoots are cut down. Further, each year 2 old shoots are removed, and 2 young are left for growth. This technology pruning will help to rejuvenate irguis imperceptibly, while practically without losing the crop. Every year, vertical shoots (¼) and side pruning are cut so that the bush grows not only upwards, but also in breadth. Extra root shoots, dry and broken branches are promptly removed.

    Growing irguu, you need to take care of it during pruning. When removing old, lignified branches, do not leave cuts open. The best tool - the usual oil paint on natural varnish. If the procedure is carried out at a positive air temperature, then you can use a garden bar.

    Care for Irga autumn

    The bush winters beautifully even in harsh climates, so there is no need for shelter. At the end of the summer season, only sanitary pruning is carried out, the site is dug up and the necessary amount of potash-phosphorus fertilizers is applied. Then garbage (branches, fallen leaves) is raked in a pile and burned. This autumn care Irga completed.

    Irga Canadian varieties are the best

    For the treatment used a solution of Bordeaux mixture, "Topaz" and other drugs. They are also recommended to spray the bushes in the fall in order to prevent.

    Of the pests can be found Irgovy seed-eater and mole-spotting. If the seed loaf eats fruits, then the mole, or rather, its caterpillars strike the leaves. To combat them, various insecticides are used: "Aktellik", "Karbofos" and others.

    Description of Canadian Irgi

    Irga - deciduous tree shrub from the family of pink. In nature, it is mainly distributed in North America. There, without any care, it grows like a weed, including on the sides of roads, as well as on forest edges, mountain slopes. In Russia, some species are found in the Crimea, in the Caucasus. The period of productive life of the shrub is quite long, at least 45-50 years. At the same time, it is characterized by its rapid growth and precociousness. The first crop is taken as early as 3-4 years after disembarking to a permanent place, by 8–10 years old, the Irga reaches the maximum possible indicators. On average, you can count on 20-25 kg of berries from a bush. They ripen in the first half of July.

    The first harvest of the irgi is removed after 3-4 years after disembarking to a permanent place

    Since the temperate climate is ideal for irgi, it is designed by nature itself for cultivation in most parts of Russia. High frost resistance allows it to winter without a special shelter, not only in the Moscow region, but also in the North-West region. As practice shows, the plant survives and bears fruit even in the forest tundra, tundra.

    Irga Canadian, cultivated by gardeners from the XVII century, is known by many different names. At home (in Canada), it is called a word borrowed from the language of the Indians, Aborigines - "Saskatoon." Other nicknames are “northern grapes”, “wine berry” (shadberry is widely used for home winemaking), “shadow bushes”, “children”, “wholesome” or “June berries”, “korinka” (due to similarity with small black grapes) .

    The average height of an adult plant reaches 2-7 m. At the same time he can have 20-25 trunks. The shoots are long, with smooth bark, slightly under their own weight. Young branches cast reddish or brick, then gradually turn brown. Krone sprawling, in the form of an ellipse or umbrella.

    The leaves are not too large (up to 10 cm in length), egg-shaped, soft to the touch. The surface of the leaf on both sides is rough, pubescent with a short soft "nap", because of which it seems covered with silver frost. Young, just blooming leaves, are painted in olive color with a brown undertone, in summer they are characterized by a bluish-gray or pinkish tide, and by autumn they become very showy purple interspersed with crimson-crimson, dark-purple and orange-golden. The edges are cut small "teeth".

    The leaves of shadberry canadian during the season change color

    The irgi root system is well developed, but superficial. Most of the roots are located at a distance of 40–50 cm from the surface of the earth, some go deeper by 90–100 cm. But in diameter they grow to 2–2.5 m. The plant very actively forms root growth, quickly spreading through the garden plot.

    To uproot an irgu completely is extremely difficult, even if you specifically set such a goal.

    Canadian Irga looks very impressive in autumn

    Flowering occurs in the last decade of April or the first of May. It lasts 12–15 days. Shrub at this time looks very impressive.

    Irga is a good honey plant attracting bees and other insects to the site. Its name in Latin (Amelanchier) means “bring honey”.

    Flowers rarely suffer from returning spring frosts, they can withstand a brief decrease in temperature to -5ºС. Buds are collected in a beautifully flowing brush of 5-12 pieces. Almost everyone is a future berry. Petals white or vanilla cream.

    Canadian irgi flowers attract many pollinating insects to the site

    The fruits of irgi rounded, in the form of an almost regular ball. Ripe berries are painted in ink-purple with a bluish blot, a little under-ridicted - in dark blue, unripe - in pink. The harvest does not ripen at the same time, therefore you can see the fruits of all three shades at once on the shrub. Of all the types of shadberry it is Canadian that has the best taste. Pleasant sweetness is due to the high content of sugars and low - fruit acids.

    Harvest irgi Canadian ripens gradually over several weeks

    Irgi berries are suitable for home canning, but apples, red or black currants are added to jams, compotes, jams to give a light sour taste. Very good for the heart and blood vessels juice from irgi. But from the freshly harvested fruit to squeeze it will not work. Berries should be allowed to lie in a dry dark place for 5-6 days. If you leave it there for 1.5–2 months, the irga will turn into something similar to raisins.

    Irga, alone or with other berries and fruits, is widely used in home canning.

    Popular with gardeners varieties

    Most of the varieties grown in garden plots are bred in Canada, but Russian breeders have their own achievements. The most popular are the following varieties:

    • Pembina. The bush is almost spherical, 4.5–5 m in diameter, very decorative at any time of the year. It differs reluctant formation of basal shoots, which for irgi, in principle, is not typical. The diameter of the berries - 1.4-1.5 cm
    • Smoky. One of the most popular varieties, almost standard. At home, grown on an industrial scale. Differs in high immunity. It grows up to 4–4.5 m. The shoots are clearly poor, the crown is in the shape of an umbrella. It blooms only in the last decade of May, when the probability of returning spring frosts is already minimal.

    There is Irga Lamarck, which is often described as one of the varieties of Canadian irgi. But in fact it is a separate type of plant. Irga Lamarck is most often used in landscape design, a flowering plant looks very beautiful.

    Irga Lamarck is widely used in landscape design.

    It differs from the Canadian one in the larger size of the flowers, in the abundance of flowering and in the coppery shade of young leaves. Irga Lamarck also bears fruit, but her berries are small (up to 1 cm in diameter), and the yield is not too high - 5-7 kg from an adult plant.

    Planting procedure

    Irga - unpretentious plant. This applies to the choice of a place for planting and the quality of the soil. It tolerates shade well, does not suffer from cold northern winds, therefore, from high shrubs it is often formed by hedges around the perimeter of the site, thus protecting other plantings. Next to Irga can be placed other berry bushes - raspberries, gooseberries, currants. In the open, culture also grows well, but does not like direct sunlight.

    Irga Canadian easily transfers partial shade, bright sun for her is not the best option

    Irga is planted in both spring and autumn. It depends on the climate in a particular region. If it is moderate, then spring is more suitable. Over the summer, the plant will precisely have time to adapt to new living conditions. In areas with a subtropical climate, landings can be planned for September and even for the first half of October, being sure that there will be at least 2–2.5 months before the first frost.

    The saplings purchased in the fall can be saved until the next spring without sacrificing quality. They are planted in a container filled with wet sawdust or a mixture of peat and sand, which is removed in a dark place with a temperature slightly above 0ºС. There are other ways - prikopat seedlings in the garden, placing them at an angle, and then pour a high snowdrift on top or simply wrap them in several layers of breathable covering material and throw snow.

    Irish Canadian saplings are most often purchased in the fall, at this time the choice is greater

    The pit for the irgi is prepared in advance, at least a few weeks before the planned landing. About 50 cm deep and 60–65 cm in diameter is sufficient. From fertilizers, humus (15–20 l), simple superphosphate (200–250 g), and potassium sulphate (70–80 g) are added to the upper layer of the fertile soil.

    Large river sand (about 10 liters) and a layer of drainage at the bottom will help to make the soil looser.

    The deep landing hole for the irgi is not needed

    When planting several plants simultaneously, at least 2–3 m are left between them. If a hedge is planned to be formed, irgu are planted in a staggered manner with an interval of 50–70 cm. Adequate space for feeding an adult plant is 6–10 m².

    Irga does not impose any special requirements on the quality of the soil, but the ideal option for it is light, but fertile loamy or sandy soil. If the soil is very poor, the shrub in search of food will begin to actively grow in breadth, forming a huge amount of basal shoots, which is almost impossible to eradicate. Acid-alkaline balance for irgi does not matter, but it does not apply too well to sour soil. If groundwater lies closer than 2–2.5 m from the surface, it is advisable to find another area, otherwise the roots may begin to rot.

    When disembarking the rootberry, the root neck should be deepened by 5–7 cm, and the seedling itself should be tilted at an angle of about 40–45º. This contributes to the active formation of adventitious roots. The tree must be plentiful (10–15 l) watered. Then the soil in the wheel circle is mulched. The shoots of the seedlings are pruned, shortening by about a third. Each should have 5–6 growth buds.

    Care culture

    Care is to maintain a pristvolny circle clean, periodic loosening of the soil, fertilization and watering. The need for winter shelter depends on the varietal qualities of a particular variety.

    Frequent and abundant irrigation is not needed. The plant has a developed root system, so it can easily do with natural rainfall. The exception is very hot and dry weather. In this case, Irga Canadian is watered every 7–12 days, spending 20–30 l per adult plant. The preferred method is sprinkling. It allows simultaneously with the irrigation to wash off the dust from the leaves of the shrub.

    If there is a technical possibility, irguu should be irrigated with sprinkling, imitating natural rainfall

    The optimal time for the procedure is early morning or late evening. If the bright sun shines, water droplets remaining on the leaves can play the role of lenses, the bush will get sunburn.


    If all the necessary fertilizers have been applied to the planting pit, in the first 3–4 years of being in the open ground, the Irish Canadian can do without additional fertilizing. Then, each spring in the near-stem circle during the first loosening, 15–20 g of any nitrogen-containing fertilizer is distributed (it is possible to prepare a solution by diluting the same amount in 10 l of water). At the end of September, the plant is fed with phosphorus and potassium so that it can properly prepare for winter. To do this, use simple superphosphate and potassium sulfate (20–25 g each) or complex preparations (ABA, Autumn). The natural alternative is wood ash (about 0.5 liters).

    Wood ash - a natural source of potassium and phosphorus

    Irga responds with gratitude to any fertilizers, especially organic ones, by increasing the growth rate and increasing the yield. Starting from the moment when the flowering ends, it is advisable to water it once every 3-4 weeks with infusions of nettle leaves, dandelion, fresh cow dung or bird droppings. Directly under the roots, no nutrient solution is introduced; it is better to make several annular grooves, departing from the trunk about 0.5 m. Approximately half an hour after feeding, the shrub is watered abundantly so as not to burn the roots. When moisture is absorbed, the soil is gently loosened.

    12–15 days after flowering, foliar feeding can be carried out using trace elements. In 10 l of water dissolve 1–2 g of copper sulfate, zinc sulfate and boric acid.

    Irga is different in growth rate, therefore it needs periodic pruning. But this should not be abused, the culture does not tolerate the procedure well.

    Most often, it is formed as a multi-bush. This configuration is provided by nature itself, it needs only a little tweak. To do this, for the first 4–5 years after landing in the ground at the Canadian ergi, all shoots are cut to the point of growth, leaving only 2-3 of the most powerful and developed. An adult shrub, therefore, should consist of 15–20 branches of different ages.

    The life of a Canadian irgi is long, so it needs to be pruned about once every 10–12 years. The signal for this is a sharp decrease in the growth rate of the shrub - no more than 10 cm per year. In this case, you definitely need to get rid of all no longer fruiting, weak, deformed, stretched shoots. All other branches are shortened to 2–2.5 m. There is another option for rejuvenation - every year to completely cut off the two oldest shoots.

    The radical method of pruning Canadian irgi - leave only hemp from the shoots

    If the diameter of the slice is more than 0.5 cm, it must be disinfected with a 2% solution of blue vitriol and carefully covered with garden pitch.

    In Canadian irgi, growing in a hedge, every available shoot is shortened by 10–15 cm annually. This stimulates the shrub to more intensive branching.

    Sanitary pruning is done every spring. It is needed to get rid of broken, dried, frozen out during the winter branches. Also remove those that grow down and deeper into the crown, thickening it, breaking the neat outlines of the shrub.

    Preparing for the winter

    Irga Canadian - cold-resistant culture. Therefore, in regions with a subtropical climate, she definitely does not need a shelter for the winter. There you can restrict the cleaning of the wheel circle from debris and update the layer of mulch.

    But in the European part of the territory of Russia, for example, in the Moscow region, the situation is different. There are winters and quite warm, snowy, and abnormally cold, with minimal rainfall. Therefore, it is better to be safe and protect young saplings, covering them with suitable-sized boxes filled with hay, sawdust, shavings. Adult specimens at the base of the shoots poured a layer of peat or humus about 25 cm in height. As soon as the snow falls, a high snowdrift is erected at the roots.

    Common diseases and pests

    Irga Canadian by nature has a high immunity, therefore, from disease-causing fungi and pests suffer quite rarely. The main danger threatening the crop is birds. The only way to reliably protect the berries from them is a fine-meshed mesh draped over a bush. But this is not always possible due to the size of the plant. All other methods (scarecrows, shiny ribbons, rattles) give only a short-term effect, for 2-3 days, not more. Birds quickly realize that these items are not able to cause them any harm.

    But still, occasionally, if summer is very cold and rainy, the following diseases can develop:

    • tuberculosis. Leaves and young shoots acquire an unnatural red-purple shade, dry quickly and wither. Small reddish-pink "warts" may appear on the branches. All branches, even slightly affected, are cut and burned. Shrub is sprayed twice with an interval of 7–12 days with a 1% solution of Bordeaux mixture or copper sulphate,
    • gray rot On the shoots at the base and in the places of attachment of the leaf stalks, on the fruits, black black-brown spots become wet, gradually tightening down with a fluffy, light gray bloom with small black patches. The most common cause is abundant watering, so it is immediately stopped. The shrub and the soil in the circle wheel are powdered with sifted wood ash, crushed chalk, colloidal sulfur,
    • leaf spot. Spots can be of various shades, from almost white to dark brown. It depends on the specific type of fungus causing the disease. For the fight used any copper-containing drugs (Topaz, Scor, Horus). Usually, if the problem is noticed at an early stage, 2–3 treatments with an interval of 5–7 days are sufficient.

    The most common pests of shadberry are usually not able to cause significant damage to the bush. But this does not mean that they do not need to fight.

    • seed seed Adults lay eggs in fruit ovaries. The hatching larvae eat seeds from the berries and pupate into them. Damaged fruits shrivel and fall off. For prophylaxis, the plant is sprayed with Karbofos immediately after flowering, and if suspicious symptoms are detected, they are treated by Karate, Aktellik or Fufanon,
    • mole mottled. Caterpillars feed on plant tissues, eating narrow passages in the leaves. Damaged leaves turn yellow and fall off. After harvesting, lepidocide or Bitoxibacillin is sprayed to prevent irgu. Also Kinmiks, Mospilan, Konfidor-Maxi,
    • leafworm. Most often, the pest manifests itself in early summer. Adults lay eggs in the leaves, turning them into a tube. 3-5 days before flowering, the bush is sprayed with Nexion’s solution or tincture of wormwood, tobacco crumbs. With adults individuals are struggling with the help of Alatar, Bitox, Binom.

    Gardeners reviews

    And you try to invent raisins from irgi. Charm! I got it by chance five years ago. Juice from the irgi berries can be obtained after drying of these same berries for 7–10 days. Once I, as it should be, put the harvest in a dry place in order to extract the juice. When it was time to take the juice, I did not have this time, so she dried up. I collected it dry in jars, and nibbled like raisins in winter. It turned out cool and tasty. When cooking compotes added to them as dried fruit.

    I, besides a few days of eating from the bushes, made jams of jugberry mixed with black cherry berries (large, similar to small cherries). Because the one and the other is not very much, and matured at the same time. Liked. Fluid got a lot of jam. Not cloying. I have planted several irgi plants in different places. I form it by the road like a tree. In other places freely grows bushes.


    After flowering, before the appearance of the ovary, the irga somewhat loses its decorativeness. Taste is an amateur: bland, like children. Ripens gradually, therefore it is a chore to collect. The main thing - it is almost impossible to uproot (either a strong man or a bulldozer is needed), it is reborn from shoots, it grows to the side (not like sea buckthorn, but still).


    We eat fresh berries of irgi, but since the ripening of berries is not simultaneous, they are always lacking for everyone. While looking for the characteristics of varieties of irgi on Canadian sites, I found not only the sale of seedlings, but also products made from berries: wine, jams and jam, dry, fresh and frozen berries, berries glazed with chocolate, various berry sauces for ice cream and yoghurts, alcoholized berries ( type of cocktail cherry) and so on. In addition, in Canada they make pies and shadberry berry pies.

    Irga Canadian in nature grows mainly in the northern hemisphere, that is, ideal for cultivation in most parts of Russia. The plant looks very attractive throughout the vegetative season. Even a beginning gardener will cope with taking care of him; he will not have to wait long for the first harvest. Berries, the taste of which children like very much, are very good for health and also differ in the universality of their purpose.
