How to propagate a blackberry - ways. Landing care.
Blackberries are propagated in the following ways: apical layers, seeds, lignified offsprings, root and green cuttings, green root siblings. And also the division of bushes, and little so far used the method of tissue culture.
Black and white varieties (or coumaric) are usually propagated by green and root cuttings, root offsprings, seeds and bush division.
The main main methods of vegetative reproduction of blackberry are two: root offspring and apical and lateral layers.
So let's look at all the methods in more detail.
1. Reproduction of blackberry seeds.
Due to high self-fertility (about 90%), most varieties and species of blackberries during seed reproduction well retain economic characteristics of maternal individuals. Moreover, IVMichurin found that up to 80% of seedlings of the second generation, inheriting maternal signs, are much more enduring than they.
In order to ensure high germination, the seeds of the blackberry must be subjected to scarification or stratification and soaked in rainwater for 2X-3 days.
Partial mechanical destruction of the hard shell is carried out by scarifying machines.
Stratification (during 1,5-2 months at a temperature of 2-5 degrees) is carried out in a mixture of seeds with river sand, peat crumb or light soil. (Those who do not know what stratification is and why it is needed read this article)
Seeds with a substrate are mixed in the ratio 1: 3, they are covered in boxes with a layer about 10 cm and moistened, avoiding overmoistening. On top of the seed-substrate mixture, cover the substrate with a layer up to 1 cm. Periodically, at least 1 times in 10 days, perform revision and moistening.
Upon completion of stratification and soaking in rain or melt water, sowing in a protected substrate to a depth of not more than 8 mm is carried out. In order to avoid thinning of seedlings, it is advisable to place the seeds during sowing according to the 3 × 3 cm scheme. The temperature in the protected soil should be maintained at 20X. Crops should be watered periodically with warm water.
After the emergence of 4 shoots, the seedlings are transplanted into the open ground (better with a lump) into a well-fertilized soil. The row spacing should not complicate the processing of plants. Distances in a row near 10, see
During the growing season, the crops should be kept in a clean condition from weeds and, if necessary, watered. In autumn, the seedlings are covered with plant remains, and in the spring they are excavated and, without destroying the soil coma around the roots, are planted in a permanent place.
Blackberries obtained from seeds, begins to give berries for 3-4-th year.
2. Reproduction using apical layers.
Sorts of creeping blackberries should be rooted in neodrevesnevshimi (end) layers of length from 30 to 35 centimeters. For this purpose, along the row of bushes cut strips of 20-30 cm deep, into which the non-woody ends of the shoots are placed and sprinkled with a layer of soil about ten centimeters.
Rooting is carried out at the end of July - August (of course, here it is worth considering the region in which you live and the variety of blackberries grown). It is necessary that before the onset of winter shoots are well established, but not sprouted above the ground. Otherwise they will freeze.
The next spring, when shoots germinate, they dig out, separated from the uterine plant and planted in a permanent place.
3. Rooting the apical buds of shoots or otherwise "pulping".
When the young shoots near the creeping blackberry varieties reach 50-60 centimeters, they shorten the tip at 10-12. This stimulates the formation of lateral shoots from the axillary buds.
When they appear small leaves and thickenings at the end (they will acquire a kind of spindle-like shape), they are pressed to the ground and sprinkled with a layer of loose ground about five centimeters.
For the next season, at the beginning of spring, the tip is cut off and left until autumn or transplanted into the nursery for growth.
At the end of a year the rooted stalk is excavated, divided into separate seedlings and planted on a permanent place. When digging and dismemberment it is necessary to keep the soil clod at the roots.
4. Reproduction of blackberry root offspring.
To obtain a planting material of blackberry varieties with erect shoots, one should choose single high-yielding healthy bushes, from which the root offspring grow around them.
Root offspring can be taken in May-June at an average stem height of about 12 centimeters (but not less than 10) or in autumn and planted in a permanent place, while retaining a clod of soil when transplanting. Root offspring should be with a thickness of shoot at the base of at least 8 mm with a root length of 15-20 cm with a powerful lobe. One blackberry bush gives up to 15-20 offspring.

5. Reproduction by root cuttings.
In autumn or early spring, dig out the root system of the fruit-bearing uterine blackberry bush, and cut it into cuttings of length 5-7, cm. For harvesting cuttings, the predominantly 1-3-summer roots are used, with an average thickness of 0,7 centimeter.
During autumn harvesting during the winter cuttings are stored in wet sand in the basement. You can plant cuttings on a permanent site or in a nursery.
For planting, cut through 70-80 cm furrows depth 10-12 cm, stack through 20 cm cuttings, fill up with loose soil and water abundantly.
During the summer, they need to be carefully treated - loosen and water.
By the autumn, good seedlings grow.
Maximum of 1 fruiting bush so you can get up to 400 blackberry seedlings.
As for the blackberry varieties, they can not be multiplied in such a way - in any case, they will grow spiked plants.
6. Reproduction of blackberry green cuttings.
In early July (preferably from the upper third of the shoot, excluding the very last kidneys) cut green cuttings, which should consist of a leaf, kidney and part of the stem.
In order for them to be as deeply rooted as possible, they must be treated with 0,3-percent indolyl-butyric acid, after which they are immediately planted in small containers filled with a mixture of peat with perlite or sand, vermiculite, etc. in equal parts.
Capacities with cuttings cuttings blackberry watered and placed for example in a greenhouse with a film coating, you can in the greenhouse. The recommended level of humidity in such cases should be about 96-100%. This ensures the receipt of quality material for reproduction.
A month later the roots appear on the cuttings, after which the cuttings are hardened and transplanted to a permanent place.
7. Reproduction by bush dividing.
Applied to blackberry varieties that do not give offspring.
When dividing the blackberry bush in each separated part, several strong young shoots with strong and well developed roots are left.
Parts of a bush with old roots for planting can not be used.
As a rule, with this method of reproduction from one old plant, you can get at least 5 young.
8. Reproduction by tissue culture method.
This little practiced method is used only to obtain a healthier, superelite seedling. For reproduction, only special cells are used which are kept in the apex of perfectly healthy, without signs of infection of plants.
Mass reproduction is carried out in boxes with the subsequent.
After this, the plants are propagated on pre-sterilized areas in the horticultural nursery.
Bookmark the site for growing blackberries
Site selection.
Under the blackberry, it is necessary to remove flat sections or the upper part of the slopes of the southern exposition, which are reliably protected from cold and dry winds by a dense net of forest strips of openwork, blown and openwork design, providing sufficient ventilation. Preference should be given to fertile, deeply drained, moist soils.
You can use under the planting of blackberries as a light loam and sandy soils. The best level of soil acidity for its cultivation is 6-6,2 pH.
Plantations on carbonate soils should be avoided, where blackberry plants will lack the elements such as magnesium and iron, which they need for normal growth.
The best predecessors are field crops, perennial legumes and cereals, many vegetables, except for solanaceae (potatoes, tomatoes and peppers) and fallow.
Soil preparation and fertilization.
The site reserved for the blackberry should be cleaned in advance from weeds, especially from root and root-crop, pests and pathogens.
Before the main pre-planting deep plowing (at 40-50 cm), 30-75 tons of overgrown manure and 75 kilograms of active phosphorus and potassium per 1 hectare are applied. On soils with a high content of humus, it is not advisable to introduce manure, since the blackberry here is rapidly growing, but weakly fructifies.
In household plots, the soil extracted from the planting grooves is mixed with organic soil (humus from cattle 4-10 kg / m2 or sheep - 2-4, or bird - 1 -1,5 kg / m2) and mineral fertilizers (superphosphate - 120-160 or double superphosphate - 60-80 g / m2 and potassium sulfate - 25-35 g / m2).
Before planting, the plowing is carefully leveled.
Blackberry planting.
The planting period is spring (before budding) or autumn (before frost starts). The seedlings used for planting should have a well-developed root system (2 litter, or even 3 root, not less than ten centimeters long), with 1-2 stems not less than half a centimeter long and necessarily with a formed kidney on the rhizome or roots. When preparing the seedlings for planting, only wrinkled and dried roots are cut out, and the healthy ones are refreshed with slices.
Planting is carried out in furrows cut at intervals of 2 meters, or in holes of depth and width up to 30 cm.
The sapling of the blackberry is placed in a furrow or fossa so that the bud at the base of the stem is at least 2 centimeter below the ground, the roots are directed in different directions, keeping the bends up, falling asleep with loose soil, slightly shaking the seedling so that the soil fills all the intercorny voids. The soil around the seedling is compacted from the periphery to the shoot.
On the periphery, the seal should be slightly stronger, which ensures a more successful placement of the roots.
In the case of using cuttings as planting material, they are laid horizontally from the furrow so that after falling asleep the soil is at a depth of not less than eight centimeters.
In order to save water and ensure better irrigation, furrows and pits around the plants fall asleep to the brim. After planting, irrigation is performed with the water norm, which ensures soil soaking to the depth of root and cuttings placement.
When autumn plantings of blackberries in the holes need to make compost or the manure. If you plant in the spring, cover both the hole and the space around it, but only after the very first watering, which is usually done a week after the landing.
Pruning of young, newly planted plants is carried out at an altitude of 22-24 centimeter.
The distance between blackberry bushes in the garden, depending on the cultivation zone and the growth force of varieties can be taken:
- for upright varieties - 0,75-1,5 m;
- for creeping and semi-growing - 2,5-2,9 m.
When using support structures, the distance in the rows between the bushes can be reduced by half.
If you grow blackberries in the bush method, then the planting pattern is 1,8 × 1,8 m.
However, depending on the zone and varieties, it must be corrected.
On the uterine plantations plants are placed according to the scheme three by three meters. This scheme is also suitable for industrial plantations placed on fertile soils using high-grown varieties.
If the variety you plan to grow has high rates of shoot formation (in case of purchase in the horticultural nursery ask beforehand, in the annotation to the seedling this may not be indicated), then such plants are planted one by one, if the deflection capacity is low, then two or three.
On wetlands, planting is carried out on beds or hills, with insufficient moisture - into grooves that should be completely covered.
Care for planting blackberries.
In the very first year it is necessary to carry out regular watering, especially in the first month. In subsequent years, watering is especially needed during the drought, during and during the ripening season. Watering with cold water is not recommended.
In the aisles, the soil contains "under steam", carrying out a deep-seated (maximum depth in the center of the aisle 12 cm) cultivation. Depending on weather conditions, up to 6 cultivation is performed for vegetation.
2 year after planting, when the blackberry plants have not yet grown, it is allowed to cultivate vegetable or sideral (syderatnye) crops in row-spacing.
In autumn (October-November), the soil in the aisles is plowed to a depth of up to 17 centimeters, with the introduction once every three or four years of humus, phosphorus and potassium fertilizers.
In the rows, in the zone where the main mass of roots is located, weeds and extra root siblings are weeded, with simultaneous loosening of the soil to a depth of up to 8 centimeters. In order to reduce the degree of damage to the roots, loosen the soil better with pitchforks.
A rather effective agro-technique is the mulching of soil with bulk organic materials, especially in the zone of distribution of the main mass of roots. In rows it is advisable to make up to 25 t / ha of manure or other organic materials. The best timing of mulching is before the appearance of offspring. Raw, poorly drained soil mulching is not recommended.
To suppress weed vegetation in the rows, we can use herbicides, for example, simazine (approximate dosage 1,1-2,2 kg ai per hectare).
To ensure stable high yields, of proper quality, fertilizers should be applied annually. Doses of fertilizer application and the ratio of nutrients depend on the actual availability in their soil, on the yield of berries and annually given from the plantation of plant biomass.
Doses recommended by E.I. Glebova et al. (1990). In the autumn for perekopku strips on each square meter is expected to make 4-5 kg of manure in a mixture with 30 grams of superphosphate and 40 grams of potassium sulfate, in the spring - 30 grams of urea or ammonium nitrate.
Top dressing of blackberries with fertilizers after harvesting is not recommended.
Formation of bushes.
Given that the creeping shape of the blackberry is very laborious in the work of care and harvesting, in large industries, preference should be given to erect form and culture on the vertical trellis.
For the trellis installation, poles with a height of at least 1,8 meters are installed through 6-10 meters in a row. They pull the first wire at a height of 0,9-1 meter, the second - 1,2, the third - 1,5 and the fourth - 1,8 m.
Sometimes limited to two wires at altitudes of 0,9 and 1,5 meters. or three - 0,9, 1,2 and 1,5. V.V. Inozemtsev and Z.Ya. Zotova (1992) recommend three ways of forming blackberry bushes.
The first method.
The shoots are intertwined between three rows of wire. All that grows after shaping is distributed to the right and left of the center of the main bush, outputting to 4 the wire located above (above all rows).
The second method.
Blackberry shoots are bred and fixed in the form of a fan, the most healthy and young shoots are fixed to the uppermost row of wire. This method is different in that shoots grow freer, and its illumination is better, and therefore in light-loving varieties and the harvest will be better. It is necessary to emphasize that this method is more laborious than the first.
The third way.
Fruit shoots are bred from young shoots in different directions and tied to rows of wire at a height of about a meter and a half meters.
The garter is carried out with twine, braid and other soft material.
Together with the garter of the shoots, trim them by 10 centimeters. This will help increase the yield.
Pruning will need to be done several times.
Autumn pruning is the complete removal of the fertilized and diseased shoots. Together with them, cut off unnecessary young shoots and shoots, which are not needed either to harvest or to form a bush.
In spring, usually cut the frozen shoots (the fact that the shoots are frozen, it becomes visible immediately after the bud blossoming).
For the remaining shoots and shoots cut the entire top leaving about 1,7-2 meters in length for sprouting and two to three meters for creeping varieties.
Prischipku blackberry produce 2 times a year. It is done to increase the yield of berries. The tops and shoots are pricked when they grow to 0,8 meters. Pinschip, as a rule, is held in May or late July. After its carrying out and growth of a bush it will be better and flower buds will be more.
Cut shoots should also be in late May and early July. At the same time, cuttings are also carried out, in which the Xunx-5 is left with the strongest shoots in the cedar and three, four in kumanyk.
In general, the best amount of shoots in the bush is about eight for obtaining high yields.
If you grow a blackberry in a fan fashion, then neighboring shoots should be separated from each other by a distance of ten or twelve centimeters, and their tops should be no more than 17-20 centimeters above the highest level of the wire (in the lower figure it is indicated by the letter "A" ) ..
There are several other ways of forming bushes.
During the first year, the young growth grows freely without a garter. When all the bushes are cut out, any signs of disease are seen.
In the spring of the second year and subsequent years, the sprouts left after trimming sparingly tie one to two to the wires of the trellis, fixed first at the height of 50-60, the second - 65-70 cm. It is practiced, and pulling two parallel wires up to a meter and a half.
Then all the shoots are between them.
Methods of growing blackberries on a wire (trellis)
In the figure you see several ways to grow blackberries on wire rows.
I always chose the second option for myself, which is in the picture below, due to the better illumination of the bush and the formation of a hedge.
If you grow blackberries more like a climbing and ornamental plant, then we recommend that you read the article on construction hands on beautiful fences and trellis for weaving plants.
Another way: on poles reinforce the cross-bars up to half a meter, and at their ends pull the wire. Fruit-bearing and young shoots are fastened between them either freely, or fruiting bind to one of them, and the young grow freely. Distributed and this method, when at different heights pull two or three wires.
The fruiting shoots attach to the uppermost one, and to the one or two lower ones - growing sprouts of substitution.
Without a trellis, separate bushes of 3-5 fruiting shoots are formed in erect and some semi-growing bushes. Some of the newly emerged sprouts are removed in April-May, and some in the middle of June.

Dear Arnold
The seed should lie in a damp, cool place for 2-3 months, for this it can be covered with a handful of damp sand, placed on the bottom of a small plastic container, and stored in the refrigerator at a temperature of 2-4 degrees, constantly maintaining the moisture of the sand, this is called stratification.
Do not store seeds for more than one year, they can rot when wet, and lose germination when dry.
Before sowing, some gardeners practice scarification - when they gently damage a part of the hard shell of the seeds with a sharp tool, this accelerates the awakening of the embryo.
The optimum soil temperature for germination is 25-28 degrees Celsius, so in spring it is not worth planting directly into open ground, it is better to grow seedlings, which are then transferred to the site.
In the spring, the seeds are taken out of the refrigerator and sown in containers or pots, under room conditions, under phytolamps 2-2.5 months before planting the sprouts on the beds, this is about the end of February or the beginning of March.
In the fall, seeds are sown in open ground, when all the plants have already shed their foliage and are dormant. In winter, damp, cold soil will be their natural environment, and in spring they will begin to germinate - this will be a natural stratification.

Blackberry Reproduction
Last year I learned about the breeding of the blackberry bouncer and decided to apply the advice in practice. Ideally, a full-fledged plant is obtained from each kidney.
The theory is very simple. In autumn, when pruning a bush, we prepare cuttings of any length. We lay them out on the ground horizontally, as your heart desires. Sprinkle with earth - a layer of 2 cm. We shelter from frost so that it falls under the arm (straw, grass, litter, foliage). In the spring we remove the insulation and wait for shoots. We plant the finished sprouts ourselves, give, share knowledge.
In the same way, I also divorced raspberry raspberry. In the photo: a blackberry on a bed (1), in a metal box (2), ready plants for planting (3), 2017 fruits of the Xenomix variety (4).

Infusion of dried fruits and leaves is good for the treatment of diarrhea and dysentery.
In diabetes, take the infusion of leaves according to the following recipe: 2 tsp. dry crushed raw material is poured into 1 a glass of boiling water and insisted for 30 min. Drink the filtered solution during the day in 3 intake.
If there are skin diseases, the blackberry will come again to help:
var used inside. And if you had to worry and you can not calm down, the infusion of twigs and leaves of the bush will again help you out.
Well helps the blackberry and with mental illness. As a sedative, the infusion of blackberry leaves is drunk with nervous excitement.

Blackberry Gem
Ripe blackberries are cleaned from the pedicels, washed in a colander and allowed to drain water. Before cooking jam, put half of the berries in the water heated to 90 degrees and withstand 3 min. After the blackberry rub through a thick sieve. To jam thickened, to the blackberry add sliced apples to sour varieties.
Puree pour into an enameled basin, put chopped apples, add water, put on fire and boil for 5 min. Then add whole blackberries and sugar and cook, stirring, until cooked.
Hot jam to spread in jars, cover with lids, tightly cork and put for cooling, without turning the jars.

I want, based on my own experience, to give a few tips for caring for the blackberry, which I have been growing for more than 10 years. I love her for the taste with a gentle sourness. I always have a good crop!
In autumn or winter, I cut the blackberry to the ground. If possible, sprinkle planting with ash, decomposed mullein. In the early spring (late March - early April) shoots appear. When 5-7 true leaves are formed at the shoots, I begin to pinch: I remove the excess and leave 7-9 pieces in the bush. I tie them to the bottom wire. I tie the fruiting shoots to the second wire, and pinch the “idle” again after the 7th sheet. And so - all summer.
The blackberry starts to keep up, and already in early August we pick berries. We do this until the frost. Watering, loosening, top dressing are mandatory. With such care a good harvest is provided to you!
#
Blackberries are responsive to mulching and top dressing. Use manure, humus, compost or peat as a mulch (layer thickness - 5-6 cm). In autumn, mineral fertilizers can be applied directly on top of the mulch, and the soil, along with mulch and fertilizers, should be dug to a depth of 6-10 cm.
In the spring, give it a nitrogen fertilizer (50-60 g ammonium nitrate per bush) and after loosening the soil spread a new layer of mulch material. If as mulch you have chosen sawdust or straw, then the norm of nitrogen fertilizers should be increased to 70 g of ammonium nitrate per bush.

Blackberries are a close relative of raspberries, and growing these plants has much in common.
But the blackberry has its own peculiarities: low winter hardiness of shoots, which are damaged even in frosts of -18 ... -25 ° С. Therefore, she needs shelter for the winter. By the way, straight-growing blackberries are more winter-hardy than creeping. For a blackberry in the garden, you need to choose a place that is well protected from cold winds and warmed enough by the sun.
It grows best on medium loamy, friable soils with a pH of 5,5-6. Shrubs growing on soils with high humus content will thank you with higher yields. The occurrence of groundwater should not be closer than 1-1,5 m from the soil surface, as the plant does not tolerate waterlogging.
#
They write a lot about how to treat blackberries with fertilizers, how to plant them, and what to cover. But about how to prune it correctly in the spring - no one's words. And for me this is a very important issue. On my blackberry, the branches grew up to 5 m in length, and all of them are so good, strong, there are a lot of berries on them - large, tasty. In autumn, I bend these branches to the ground and cover them with fallen leaves for the winter, and in the spring I open and look at them, not knowing how to shorten them so that this does not affect fruiting. Maybe trellises do? But then, probably, the branches will grow even more. And will it be good for the bush?

I want to talk about how I prepare my big-berry blackberry Black Prince for the winter.
I twist her whips in rings, tie, lower to the ground and press with bricks. Nearby, I drop in plastic bottles (1 pc near each bush), in which I make a cut through the side and put a rag dipped in diesel fuel inside, this is from mice (and it helps a lot, by the way). After the onset of frost, I cover the blackberry with pre-prepared cardboard, spread the film on top and press the edges with bricks. And in the spring my blackberry looks good again and then makes me happy with large tasty berries.

Ask how to grow blackberries with seeds. There is simply no way to describe agricultural technology to everyone - more than 300 letters have accumulated. Blackberries are propagated by root offspring, root cuttings and seeds. During seed propagation, all varieties retain their species characteristics. So, how do you grow blackberries with seeds?
I take a wet sand layer of 5 mm. Sow the seeds in a container and keep it for three months in a cool room at a temperature of 2 to 5 °. Regularly moisturize. You can keep the container in the refrigerator, in the lower compartment for fruit. In early March, I transfer it to a warm place (20 °) for germination and growth. It is important to ensure that the soil does not dry out, and does not over-moisten. When two leaves appear, seedlings are transplanted one by one into the pots.
Blackberries, grown from seeds, begin to bear fruit for the third or fourth year after disembarkation.
It takes root on all soils, except wetland and sand. The distance between the bushes is 1,5-2 m. For planting, I choose a sunny, dry, protected from cold winds place. Planting pit - 40 × 40 cm, add humus, ash, 50 g of potassium salt. I mix, water, add good soil and plant a seedling on it so that the roots do not get burned. I fall asleep from above, watering again.
Must mulch, syplyu foliage, humus. Roots well winter.
Fructifies on last year's branches, new branches are the pledge of the next harvest. After harvesting, and this is October, I cut off all last year's shoots, which have already been fertilized, completely to the ground level, leaving no stumps. At the same time, I cut the bush and leave five or six stems, I bend to the ground and cover the root part of any mulch, I cover it with old rugs and throw it with snow.
In the spring, when the snow melts, I open it, so that the bushes are not forbidden. The leaves are still green, as if there was no winter. In April I take pictures, but I do not tie them yet-the flashes start to rise a little, and the leaves wither and fall off. Then new leaves start to blossom.
Blackberry has anti-inflammatory, wound-healing, anti-burn, bactericidal, diaphoretic and soothing effects. We have frosts to -NNUMX ° and snowless winters, but the blackberry survives, has never frozen. For a season I feed three times: in the spring, during flowering and fruiting. Watering abundantly, once a week.
I do not send cuttings, I can send seeds. And here is my recipe for a delicious jam.
I dig out the blackberries, wash 1 kg of berries and dry them on a towel. Then put half of the berries in a saucepan, add a little water and cook for 5 min. I pass the mass through a sieve. I add the remaining berries and 0,8 kg of sugar, I cook another 10 min, stirring hot jam. Then I spread it into jars and roll it up.

- When you buy a plant, try to find out the name of the variety. Obviously, you bought a blackberry variety that requires shelter for the winter. Without it, the plant freezes, and therefore does not bear fruit.

Blackberries are not harder to grow than raspberries or gooseberries, but its yield is much higher. With proper care with 1 bush blackberry you can get up to 20 kg of berries per season.
A place to plant a blackberry is not the most important thing. This culture is good because it grows and yields crops on different types of soils. But it is nevertheless desirable that the earth be enriched with humus or compost. It is better to plant a blackberry in the middle or end of spring - to where there is enough sun and there is protection from the wind. So the fruits will be sweeter, and they will ripen earlier. Plants are planted in rows with row spacing so that it is convenient to care for the blackberry, and from north to south - so that the bushes have enough sunlight. Watering after planting, mulch with compost, humus, straw or mowed grass. This mulch inhibits weed growth,
stores moisture and enriches the soil with nutrients. Saplings quickly take root, develop powerful shoots. As we grow, we tie them to the support so that they do not hang to the ground. If they grow to 2 m, pinch them to develop side shoots and increase yield.
For top dressing of blackberry we use humus and infusions of herbs. You can still stir 1 glass of wood ash in 10 l of water and pour this solution on the plant.
Another important point: the garden blackberry is thermophilic, so we always take care of the winter shelter. First we cut off the fertilized shoots, the rest we put on the ground, we cover them with non-woven material, and then we pour a layer of sawdust. In the spring, as soon as frosts pass, we remove the shelters and fix the whips on the trellises.
