Fruit and berry plants

Plant irga, or cinnamon (lat.Amelanchier) belongs to the genus of the tribe Apple of the family Rose and is a small tree or deciduous shrub. The Latin name irgi has either Provencal or Celtic origin and is translated as "to bring honey". The British call irgu a shade bush, June or useful berry, and the Americans have retained the name given by the native inhabitants of the country, the Indians, "Saskatoon" to it. In the nature of the northern hemisphere of the planet, according to various sources, from 18 to 25 species of irgi grow, and most of them are in North America.
In nature, Irga grows on forest edges, on rocks, and even in the tundra zone. In culture, about ten of its species have been mastered, grown both as ornamental plants and for the sake of useful, sweet berries, which children love very much.

Planting and caring for the irga

  • Landing: both spring and autumn planting is possible, but autumn planting is preferred.
  • Lighting: bright sunlight.
  • The soil: loamy or sandy loam, fertile, with deep groundwater.
  • Watering: only in severe drought.
  • Top dressing: from the fourth to fifth year of life, every year the soil in the trunk circle is dug up with humus and mineral fertilizers, and from spring to mid-summer, irga is fed on pre-moistened soil with solutions of liquid organic matter at the rate of 5 liters for each bush.
  • Cropping: from the third year of life after leaf fall for sanitary purposes.
  • Reproduction: specific plants can be propagated by seeds, but varietal plants can only be propagated vegetatively: by offspring, green cuttings, layering, dividing the bush and grafting.
  • Pests: seed-eaters, speckled moths, spider mites, aphids.
  • Diseases: septoria, phyllosticosis, tuberculariosis.

Botanical description

The irga shrub looks attractive during the blooming of the leaves - it is as if shrouded in pubescence, like silvery-white frost, but when numerous flowers begin to appear on the irga after the leaves, it miraculously transforms, and before you appears a magic densely strewn with white or pink flowers in graceful racemose inflorescences a vision worthy of an artist's brush. Irgi leaves are also delightful - green or olive-pinkish. As soon as the flowers of the irgi fall, the pubescence on its leaves also disappears, and nothing distracts the eye from the slender bush with a well-leafy crown and velvety gray-brown bark with a pink tint on the trunk.

When the time for fruiting comes, small "apples" appear on the irga, collected in a brush - at first they are creamy white with a pink blush, then gradually darken to a dark purple, red-purple or violet color. The fruits of the irgi are pleasant to the taste, juicy and sweet, they are eaten with pleasure by children and pecked by birds, spreading the seeds around. With the arrival of autumn, you will again turn your gaze with admiration to the irgi bush, when its foliage will sparkle with autumn colors of the richest color palette from bright yellow to pink-orange and red-scarlet tones with purple-violet highlights against the background of some preserved green leaves ...

In addition to the impeccable decorative characteristics, the irga is distinguished by drought resistance, early maturity, winter hardiness and rapid growth; it blooms and bears fruit most abundantly on the apical shoots of the last year. Irga serves as a reliable and hardy stock for dwarf apple and pear trees. The irgi bush lives for 60-70 years, over time its stems turn into real trunks that can reach 8 meters in height. Irga is one of the best honey plants. Against the background of all these wonderful qualities, the only drawback of irgi is the abundant root shoots, which will have to be fought constantly. But the irga is worth the effort spent on its cultivation, because, in addition to beauty, it attracts gardeners also with its healing properties, which we will discuss in a separate chapter.

Planting irgi

When to plant

Irgi planting is carried out both in spring and autumn, although many experts recommend an autumn planting. Find a bright place for the irgi so that its shoots do not stretch out in search of light and bear fruit in full force. The soil for irgi is best of sandy loam or loamy, and although the irga is not capricious in this matter, the soil should be fertile so that less root growth is formed around the shrub, because if the roots have enough nutrition, they will not "scour" around. And there will be more berries on the bush than leaves if the irga grows in humus-rich soil.

The acidity of the soil does not play a special role for irgi, but in areas with high groundwater, it is better not to plant this plant - its root system goes 2-3 meters deep. They begin to prepare a site for autumn planting in spring - they clear it of weeds and keep it under black steam until autumn. Before planting, the site is dug up with phosphorus and potash fertilizers at the rate of 40 g each per m². Digging depth - 10-15 cm.

How to plant

There are no difficulties in this matter either. Irgi seedlings should be planted one or two years old. They are placed on the site in a checkerboard pattern (if you decide to plant several bushes), the distance between the specimens is maintained from half a meter to one and a half meters. The size of the pit is approximately 60x60x50 cm.

Planting irgi is carried out according to the same principle as planting such berry bushes as gooseberries, currants, raspberries, blackberries, blueberries, actinidia and honeysuckle: the top arable layer of soil removed from the pit is mixed with sand and rotted compost in a ratio of 3: 1: 1, a bucket or two humus is poured into the pit, 150 g of potassium fertilizer, 400 g of phosphate are added. Then, at the bottom of the pit, a mound is formed from the prepared soil, a sapling of irgi is placed on it, the roots of the plant are straightened and the soil is filled with soil mixed with compost and sand, slightly compacting it. The root collar of the seedling should not be buried.

After planting, the bush is watered with a large amount of water - 8-10 liters, and when the soil settles, the soil is poured into the hole so that the planting site is leveled with the surface of the site. The soil around the bush is mulched with peat, humus or dry soil. After planting, the ground part of the bush is cut to 15 cm, leaving 4-5 well-developed buds on each shoot.

Irga care

Growing conditions

Irga is so easy to care for that after planting, one could forget about it before harvesting. But, like any other plant, it still needs a minimum of your attention. Plus, if you take good care of the plant, it pays for your efforts with bountiful harvests and well-groomed beauty. And you just need to water the irga, weed the weeds around it, sometimes cut the bushes and make seasonal fertilizing.

Since the Irga is drought-resistant and its root system goes deep into the soil, where there is always moisture, watering the shrub is carried out only in the driest season, using a hose with a diffuser for this, in order to simultaneously wash off the dust from the leaves. It is better to do this after the heat of the day subsides - after 16:00. After moistening the soil, remove the weeds and loosen the soil around the bush.

Fertilizer

From the age of four to five, annually, 300 g of superphosphate, 200 g of chlorine-free potassium fertilizer and 1-2 buckets of humus are introduced into the trunk circle for digging, having retreated 20-30 cm from the root collar. From spring to mid-summer, irgu is fed with liquid organic matter - five liters of a ten percent solution of chicken manure for each bush. Liquid fertilizers are applied at night after abundant watering or rain, and dry fertilizers are scattered around the trunk circle, stepping back 30 cm from the bush, they are embedded in the soil, and then the area is watered. As the irgi grows, the amount of fertilizer is increased.

Transfer

It is difficult to transplant an adult irga - its roots go too deep into the ground, so be responsible when choosing a site for a plant so that you do not have to transplant it later. But if the need for a transplant nevertheless arises, keep in mind when digging up a plant that the root system of a middle-aged irgi spreads in depth and in width by about 2 meters. In a bush of seven to eight years of age, the diameter of an earthen coma, necessary for painless rooting of a bush in a new place, should be a meter-meter and a quarter, and a depth of about 70 cm - the rest of the peripheral roots can be left in the ground, the irga will quickly grow them in a new place.

The older the bush, the larger the diameter of the earthen coma should be when removing the plant from the soil. Dig a bush, transfer it to a new place along with an earthen lump, lower it into the prepared hole, add soil to the hole and compact it. Do not forget to water the transplanted bush abundantly and mulch the tree trunk circle.

Irga in autumn

In the fall, after fruiting is complete, carry out sanitary and thinning pruning of the irgi, transplant the bushes, if necessary, apply fertilizer by digging up the area and removing the fallen leaves from it - this is, perhaps, all that you can do for the plant in end of the growing season. The plant hibernates without shelter, since it easily withstands forty-degree frosts.

Pruning irgi

When to trim

Despite the seeming ease with which the irga tolerates pruning, it is better to carry out this procedure only as needed. And so that such a need arises as rarely as possible, remember a few rules:

  • plant the irga in a sunny place so that the light penetrates into the very thick of the bush;
  • it makes sense to prune only low varieties of irgi, since a high-grade bush, when it grows, you will not cut even from a stepladder;
  • pruning begins a year or two after planting the bush in early spring before the start of sap flow.

How to trim

In the first years of growth, leave only a few of the strongest zero shoots from the root growth, and remove the rest. When the shrub has a sufficient number of stems, remove the two oldest ones annually, and leave the same amount in return from the root growth - this will allow the bush to rejuvenate every year without reducing the yield. In young bushes, all vertical shoots are shortened by a quarter of last year's growth.

In subsequent years, prune the side branches to stimulate the growth of the crown in breadth, otherwise you will soon be unable to harvest even from a stepladder. Sections on annual shoots can not be processed, but treat the cuts of older branches with oil paint on natural linseed oil - garden var is not used in the cold. In addition to the formative function, pruning irgi performs a sanitary function: remove broken, dry and thickening shoots, that is, those that grow inside the bush.

Don't forget to fight the root shoots. If you need to rejuvenate an old shrub, cut it back into a tree stump.

Reproduction of irgi

Reproduction methods

The most common oval-leaved irgu can be propagated both by seeds and vegetatively. Large-fruited varietal irga reproduces vegetatively - by offspring, grafting and green cuttings. But in general, species of irgi reproduce by seeds, and varieties - only vegetatively.

Growing from seeds

Irgi seeds can be extracted from ripe fruits and immediately planted on well-fertilized beds to a depth of no more than 2 cm, watered abundantly and mulched with straw or dry leaves. Seeds that have undergone natural stratification in winter will sprout next spring, but do not panic if they germinate in the fall. In the spring, the seedlings are planted more freely and are looked after - they are watered, weeds are removed from the beds, and they are fed with nitrogen fertilizers. In the first year, the seedlings grow in height up to only 10-12 cm, and in the second - up to 40-50 cm. In the third year, the matured irgi seedlings are transplanted to a permanent place.

Propagation by grafting cuttings

In the fall, prepare rootstocks, that is, two-year-old rowan seedlings, which grow in large numbers in parks and plantings - just pull them out of the ground after rain. You can go a long way, growing rowan seedlings yourself - in the fall you sow in the ground, in the spring you get friendly shoots, and in the second year - rootstocks. It is necessary to plant cuttings of irgi on mountain ash in the spring, during the period of sap flow, at a height of 10-15 cm from the root collar. This is done like this:

  • the grown scion is dug up, the roots are washed and the stock is cut horizontally at a height of 10-15 cm from the root collar;
  • the cut is split with a knife in the middle to a depth of 3 cm;
  • an upper oblique cut is made on the scion handle, and a lower cut in the form of a two-sided flat wedge up to 4 cm long is made 15 cm lower - one side of the wedge is just below the kidney, the second is on the opposite side from it;
  • the scion wedge is tightly inserted into the rootstock split, but the upper part of the wedge is not included in the split;
  • the junction is wrapped with tape, and the upper cut of the scion is treated with garden varnish;
  • the stock is planted in a box with a mixture of sand and peat, deepening it to the grafting site, and the box is placed in a cold greenhouse or greenhouse: the higher the temperature in the room, the faster the scion will take root;
  • when callus begins to form on the part of the wedge that has not fallen into the cleavage, the film is removed, and the grafted irga is planted in open ground;
  • rowan shoots formed on the rootstock below the grafting are cut out.

Reproduction of irgi green cuttings

Cuttings are cut from the tops of any branches of well-developed five to six-year-old bushes in the first half of summer. The length of the cuttings is 10-15 cm. Remove the lower leaves from the cuttings, leaving only 1-2 pairs of the upper ones. Place the lower cuts of the cuttings in a root-forming agent for 6-12 hours, then rinse them with clean water and plant them at an angle at a distance of 3-4 cm from each other in a cold greenhouse in clean soil, sprinkled on top with a layer of sand 7-10 cm thick. The greenhouse dome should be 15-20 cm higher than the cuttings.

After planting, pour the cuttings through a fine sieve so that the water splashes out instead of pouring out. Cover the greenhouse after watering. The temperature in the greenhouse should not rise above 25 ºC, so the cuttings should be regularly ventilated by removing the greenhouse dome. Keep the soil slightly moist. After two to three weeks, the cuttings take root, so the dome of the greenhouse is removed during the day, and when the cuttings are a little stronger, the greenhouse is left open at night.

Three-week-old cuttings develop a strong fibrous root system, and they are planted for growing on a training bed, and as soon as they take root, they are fed with slurry diluted with water 6-8 times, or mineral fertilizer - 30 g of ammonium nitrate dissolved in a bucket of water. The cuttings are looked after as if they were an adult plant, and the next fall they are transplanted to a permanent place.

Reproduction by layering

For this breeding method, developed one-year shoots or two-year branches with strong growths are chosen. It is better to drip in the layers in early spring, as soon as the soil warms up. The top layer of soil under the bushes, from which you will take the layers, needs to be dug up, fertilized and leveled. Then make grooves in the soil, lay low-growing shoots in them and fix them in the groove, and pinch the tops. Wait until young shoots with a height of 10-12 cm develop from the buds, and sprinkle them halfway with fertile soil or humus.

After 2-3 weeks, as soon as the shoots grow another 10-15 cm, sprinkle them halfway down again. Rooted cuttings are separated from the bush in the fall or next spring and transplanted to a permanent place.

Dividing the bush

This method of reproduction is resorted to in the event that it is necessary to transplant a bush from place to place. The best time is early spring before the buds swell or autumn, a month before frost. After removing the bush from the ground, cut it off, removing the old branches, and, freeing the roots from the ground, divide the rhizome into several parts. Sometimes you have to act with an ax.

Each cut should have a healthy ground section with at least two shoots and a well-developed root system. It is better to remove old roots, trim the rest, after which parts of the bush can be planted in prepared pits.

Irgi pests and diseases

In general, Irga is quite resistant to diseases and pests, but sometimes it suffers from tuberculariosis (drying of branches), septoria (gray rot) and phyllostidous leaf spot.

Tuberculariosis manifests itself first by the browning and drying of the leaves, then the branches wither, and red tubercles form on them. Sick shoots are cut and burned, and the plant is sprayed in spring with copper sulfate or Bordeaux liquid.

Phylostictic spotting can be diagnosed by brown-brown spots on dying and falling leaves. The leaves damaged by spotting are removed, and the bush is treated before and after flowering with Bordeaux liquid.

Gray rot is also manifested by brown spots on the leaves, which gradually blur, the leaves turn yellow, become covered with gray fluffy mold and fall off.

Gets sick septoria a plant suffering from excess moisture in the roots, therefore, before the plant dies, normalize irrigation irgi or transplant it to where the groundwater lies deeper. As a treatment and prevention, the plant is treated with the same Bordeaux liquid, as well as topaz, oxychom, cuproxate.

The main pests of irgi are irrigate seed-eater and moth-moth. The seed eater damages the fruit by feeding on the seeds of the irgi, and it pupates in the fruit. And the caterpillars of the speckled moth mine the leaves of the plant, which makes them dry and crumble. In the fight against these pests, the treatment of irgi with actellik, karbofos or fufanon is used.

Types of irgi

As already mentioned, more than ten types of irgi have taken root in the culture. We will briefly introduce you to some of them.

Irga spicate (Amelanchier spicata)

Deciduous shrub or tree up to 5 m high with numerous shoots forming a dense oval crown. Adult branches are dark gray, young ones are reddish brown. The leaves are ovoid, up to 5 cm long and up to 2.5 cm wide - at the time of opening they are white-tomentose, dark green in summer, in autumn - different shades of red-orange. Fragrant pink or white flowers are collected in short, woolly erect inflorescences. Fruits are round, purple-black with a bluish bloom, sweet, up to 1 cm in diameter.

The plant is winter hardy, it is also resistant to drought, smoke and gas. The growing season is from April to early October, bears fruit from the age of four. A native of North America spike irga.

Irga alnifolia (Amelanchier alnifolia)

Also native to North America, from its western and central regions, where it lives on hillsides, in forests, along the banks of streams and rivers. Shade-tolerant. Young leaves, shoots and buds in racemose inflorescences are pubescent, the petals of the flowers are directed vertically upward, which is why their centers are not visible. Fruits are spherical, slightly elongated, black. In culture since 1918.

Irga canadensis (Amelanchier canadensis)

Also lives on the slopes of rocks, the banks of reservoirs and rivers. This is a large shrub up to 6 m tall or a tree reaching 8-10 m.Shoots are thin, slightly drooping, ovoid leaves, up to 10 cm long, at first brown-green, like felt, in summer they are gray-green, and in autumn they acquire crimson-golden shades different intensities. Drooping racemose inflorescences consist of 5-12 white flowers that contrast with reddish shoots. Fruits are round, dark purple with a bluish bloom, have a sweet taste.

The species is frost-hardy, undemanding to the quality of the soil and to the level of moisture, has high decorative properties. In culture since 1623.

Irga Lamarckii (Amelanchier lamarckii)

It is distinguished by its beauty and attractiveness throughout the season, therefore it is often used for landscaping both as a solo plant and in group plantings. Both Irga canadensis and Irga Lamarca are excellent rootstocks for pears and apple trees, increasing the winter hardiness of the scion and its ability to grow on too wet soils, which is not typical for stone fruit trees.

Irga oval, or ordinary (Amelanchier ovalis)

Originally from Central and Southern Europe. It grows in dry places - in forests, pine forests, on the slopes of rocks. This is a shrub up to 2.5 m in height with young shoots silvery from pubescence, which over time become naked, shiny and acquire a red-brown tint. Leaves are ovoid, dense, serrate along the edge, up to 4 cm long - immediately after opening they are like tomentose, dark green in summer, and reddish-purple with the onset of autumn. White flowers up to 3 cm in diameter are collected in apical brushes. Fruits are bluish-black with a bluish bloom.

This species is drought-resistant, prefers rich calcareous soils. It hibernates without shelter only in the southern regions. In culture since the 16th century.

In addition to the species described, irga is grown in culture: low, smooth, round-leaved, profusely flowering, pleasant, Asian, Bartram, Kuzik, obovate, blood-red, Yut and Jack's irgu.

Irgi properties - benefits and harms

Beneficial features

How is Irga useful? Irgi fruits contain pectins, mono- and disaccharides, vitamins C, P, A, vitamins of group B, trace elements lead, copper, cobalt, tannins, flavonols, fiber, malic acid and many other substances necessary and useful for humans. The irgi fruit contains ascorbic acid and a large amount of carotene, which are powerful antioxidants that increase the body's resistance to stress and infectious diseases, prevent the development of cancer and slow down the development of Alzheimer's disease.

In addition, the carotene contained in irgi fruits prevents the development of cataracts, cures night blindness and improves vision. The pectins contained in irge lower the level of cholesterol in the blood, remove radionucleides, heavy metal salts and other toxins from the body, having a beneficial effect on the work of the heart.

Irga juice, due to its astringent and anti-inflammatory effect, helps in the treatment of colitis and enterocolitis. They take the fruits of irgi, which have a sedative effect, with insomnia and increased nervous excitability. Irga is used for diabetes - a decoction of its bark is used to rinse the mouth, and the gruel from the leaves of the irga is applied to ulcers.

Contraindications

Irga is contraindicated for people with individual intolerance to this product and hypotension. Drivers should not drive after eating irgi berries due to their strong sedative effect. There are no other contraindications.

Irga is an unpretentious ornamental shrub of the rose family, which gives a bountiful harvest of useful, very tasty berries. Depending on the variety, it can be a spreading bush, or a tree.

Her homeland is North America, where shrubs can be found on the forest edge, or in the mountains. In the 17th - 18th centuries, irga became widespread in Europe, where it was used as a decorative park culture. Under natural conditions, it is found in the Crimea and the Caucasus.

For a garden plot, a large-fruited irga is best suited; growing varietal bushes is not difficult. Flowering varies by region: in the north of the Krasnodar Territory - the end of April and the beginning of May in the Moscow region - at the beginning of June.

Harvesting of irgi begins in July and continues until early September.


Features of aralia

Aralia Manchu, or high is a tree or shrub, characterized by rapid growth, and its height can vary from 1.5 to 12 meters. The straight trunk reaches up to 0.2 m in diameter. The radial root system is placed in the ground at a depth of 10 to 25 centimeters. An interesting fact is that at a distance of 2 to 5 m from the trunk, the beginning of a strong branching of the roots is noted, while they sharply bend and go down to a depth of about 0.6 m.And on the surface of the leaf petioles and on the trunk there are a huge number of sharp thorns ... The complex double-pinnate leaves include from 2 to 4 pairs of lobes, and they consist of 5-9 pairs of leaves. The large apical inflorescences, reaching 0.45 m in diameter, include umbrellas, consisting of small flowers of white or cream color. The fruit is a berry of black and blue color, reaching 0.3–0.5 cm in diameter, inside which there are 3–5 seeds. The first flowering of the aralia tree, which grows in the wild, is observed only in the 5th year of growth. Such a plant blooms in July and August, and the ripening of the fruits is noted in September and October.

Reproduction of irgi

Reproduction of irgi by varieties is carried out using vegetative methods, and by species - using seed.

Seed propagation

Immediately after removing the seeds from the berry berry, the gardener can plant them. But the beds must first be well fertilized, and the depth of the seedlings in the soil should be about 2 cm.Further actions are standard:

  • abundant watering
  • mulching with dry fallen leaves or straw.

Seeds exposed to natural stratification in the winter cold will sprout with the onset of next spring, and then they should be planted more freely. Then they are fed with nitrogen-containing fertilizers, watered and cleaned from weeds.

The growth dynamics of seedlings is as follows:

  • during the first year they will grow up to 10-12 centimeters
  • next year, their height will reach 40 to 50 cm.

The transplanting of mature seedlings to a permanent place allotted to them on a land plot is carried out in the third year.

Propagation by grafting cuttings

As rootstocks, it is recommended to use rowan seedlings that have reached 2 years of age. They are harvested in the fall. Cinnamon cuttings are grafted onto these rowan rootstocks in the spring, when sap flow begins.The distance of cuttings from the root collar is about 10-15 cm.The grafting procedure includes the following steps:

  • the grown scion is dug up, after which its roots must be washed
  • the stock is cut horizontally. The cut should be 10-15 centimeters from the root collar
  • in the middle, this cut is neatly split with a sharp knife to a depth of 3 cm
  • 2 cuts are made on a handle serving as a scion:
  • upper - oblique
  • bottom - should be wedge-shaped with two shallow sides. It is very important that its length is 4 cm.In addition, one edge of the wedge should be slightly below the location of the kidney, and the other should be on its opposite side
  • the scion wedge is inserted into the split created on the rootstock without excessive force, but the wedge is tightly inserted. It should be ensured that the part of the wedge located on top does not enter the split.
  • the section of the insert is wrapped with tape, while the upper (beveled) cut of the scion cuttings is processed with a previously prepared garden pitch
  • the stock is planted in a wooden box filled with a mixture of black peat and, preferably, river sand, so that the grafting site is located at the very surface of the mixture
  • the box is installed in a cold, not a warm greenhouse or in the same greenhouse
  • with the beginning of formation on the part of the edge of the wedge located above the split, the so-called. callus is necessary:
  • remove the film
  • plant a grafted corinka on a land plot without shelter
  • shoots on rowan rootstock, which appear below the site of the graft, will need to be cut out.

Propagation by green cuttings

The time when it is recommended to cut the cuttings is until mid-July. For this, the tops of the branches of the bushes are selected that have reached the age of five to six and, we emphasize, are well developed. The most suitable length of the cutting is within 10-15 cm. The sequence of actions is as follows:

  • a maximum of 2 pairs of upper leaves are left on the handle, and all lower ones are removed
  • slices located on the bottom of the cuttings, for a quarter to a half of the day, are placed in a means that stimulates root formation
  • then the cuttings are washed and planted at a slight slope at a distance of about 3-4 cm from each other in a cold greenhouse with a dome located 15-20 centimeters higher than the highest of the cuttings. The ground is covered with a layer of sand (preferably river) with a thickness of 7 ... 10 cm
  • cuttings are watered with water so that it does not pour in one stream, but is sprayed. For this, a fine mesh strainer is used.
  • greenhouse is covered
  • cuttings are regularly ventilated by removing the greenhouse dome
  • the soil is not very moistened
  • when the cuttings take root (it will take from 3 to 4 weeks), the greenhouse dome must be removed for all daylight hours
  • when the cuttings are noticeably stronger, the greenhouse is not covered even at night
  • cuttings that have reached 3 weeks of age are planted on a special bed for the purpose of growing
  • the gardener, noticing that the cuttings have already successfully taken root, feeds them:
  • ammonium nitrate - 30 grams. Dissolve in one bucket of water
  • or slurry of manure, which must be diluted 5-8 times with clean water
  • care for cuttings is carried out similarly to this procedure in relation to adult plants
  • transplantation to a permanent place allocated on the land plot is made with the arrival of the next autumn.

Reproduction by layering

To implement this variant of vegetative reproduction, the following are suitable:

  • 2-year-old branches with strong growths
  • well-developed 1-year-old shoots.

The optimal time for reproduction by layering is early spring, but the soil must have time to warm up. Stages:

Reproduction by dividing the bush

The optimal reproduction time in this way is autumn, about November, one month before the arrival of severe frosts, or early spring, at a time when the buds have not even begun to swell. After removing the shrub from the ground, its old branches are removed, and the roots are freed from the soil. Then the rhizome is divided into parts. Often, an ax comes to the rescue here.

Each part must be characterized by the presence of:

Experienced gardeners recommend removing old, already depleted roots, and those that remain - trimmed. Upon completion of these actions, parts of the irgi bush are planted in previously prepared pits.
