Caring for fruiting grapes Memory Dombkovskaya is not particularly different from other varieties. It is only necessary to restrain the growth of the vegetative mass.
In the spring (March 25 - April 5) as soon as possible, you need to remove the main shelter, dry the vines, sprinkle 3% of the blue vitriol (if necessary), cover again with agrotex, and on top of it with a film or polycarbonate. In the warm edges this can not be done (photo 1).
In Siberia, leaves are harvested in the crop area, lightening brushes.
Under the arcs, young green vines grow 70-100 cm to 1-10 June. Then we remove the shelter, tie the vines to the trellis on the first and second wires from the ground, and the sleeves horizontally or at an angle of no more than 45e. Young shoots are distributed vertically.
Constantly in June - August, we tie the vines to the wire, thin out the crown, remove thin, old-growthed, old twins.
Usually, the minting is carried out when straightening the crown of the shoot (approximately August 20), cutting the top by 25-40 cm.
We hold it in July and early August. Embossing is the power savings. We cut off the shoots at the height of an outstretched arm with a shears, approximately above the 18-20 leaf. This is enough for the qualitative development of the plant and the education of the crop. In this case, the growth of stepchildren is activated. We remove them twice, and the last 2-3, in the zone of chasing, shorten.
We process with tank mixtures with the addition of boric and, citric acid (10 g each) for better filling of berries and a set of sugars.
The first spraying - at the beginning of the growing season, the second - before flowering, the third - in the pea phase, the fourth - at the end of the growing season, without nitrogen, iron vitriol, iodine, potassium permanganate, but with the addition of superphosphate infusion (25-30 g).
One of the main components of the tank mix is Novosil - an immunostimulator and an immuno-modulator for a plant. Grapes react very positively to it. The leaf becomes dark green, the plate thickens, the berries ripen faster, the crop rises.
Pruning grapes Memory Dombkowska
In mid-September, harvest. After that, we immediately remove the vines from the trellis and do a preliminary pruning: we remove weak, thin, small shoots. The rest is cut to a warm to the touch vine. We put the crown on the crossbars in the trenches, put arcs or without them close with agrotex and film. This will save the sheet machine from frost.
At the beginning - mid-October, we carry out the final pruning, leaving the number of vines with a margin of 1.5 times, with 50-70 eyes. The final pruning occurs in the spring, after bud break.
Getting ready for winter
Cut the vines into bundles, spray the shoots and soil with 3% iron sulphate and sprinkle it with ashes immediately (photo 2). It sticks to the vines, it protects them from diseases and mice. In addition, we sprinkle the soil with sawdust with creolin and lay out the poisoned bait. These procedures reliably protect plants from mice.
Then we harbor trenches for the winter, boxes. We put old boxes on bound vines, on them agrotex, then we overlap them with boards, put 2 layers of cardboard on them, then foamed polyethylene 10 mm thick (photo 3) and a film. This protected the immature grape vines during the winter of 2013-2014, and a satisfactory harvest was obtained.

The grapes of “In Memory of Dombkovskaya” were bred by an enthusiast from Orenburg, Shatilov, Fyodor Ilyich, about thirty years ago. This variety is also often referred to as black seedless winter hardy variety (CSR).
Fyodor Ilyich called this variety of grapes as a sign of respect for his colleague Yanina Dombkovskaya, who collaborated with him. In order to get the variety “In Memory of Dombkovskaya”, the breeder crossed the “Dawn of the North” together with the variety “Kishmish Unique.” After some time, Fedor passed tens of thousands of cuttings to Chelyabinsk garden farms, where the incredible harvest of grapes ChBZ was grown.
Description and distinctive characteristics
Grapes "Memory Dombkovskoy" has an interesting description, and below is a photo. This variety is table-sod. Is different strong and fast-growing shrubs and strong vines. The latter grows five meters in a season and fully matures even in extreme conditions. Leaves with long petioles are dark green in color, and the berries are medium in size, grow in large clusters and at the same time appear almost black.
It ripens from mid-August to late September (it all depends on the climate). Ripe berries, which continue to grow on the bush, do not crack and become more and more sweet. And by the end of autumn turn into a kind of raisins. Pulp berry burgundy color with a pronounced sweet-sour taste.
Features of growing
Like any other variety, the grapes of “Pamyati Dombkovskaya” require special growing conditions. So, you need proper watering and suitable soil.
The grape "Memory Dombkovskaya" requires as much sunlight as possible. Based on this, a reasonable solution would be to plant this bush on the south side of the site.
The bush is quite demanding of the soil, so if the latter does not possess high fertility, there is a need to introduce organic fertilizers.
This variety loves loamy soil or black soil, but does not tolerate the land in which water stagnates. The soil for the grapes should be prepared in advance so that she has time to settle.
So, it is necessary to carry out the following manipulations:
- Dig the right number of holes in one meter depth and a distance of 1.5-2 meters between them.
- Pour rubble or gravel into the pits, which will serve as drainage.
- Put humus mixed with phosphate-potassium fertilizers on top.
- Securely fasten a peg in the middle of the pit on which the vine will be tied.
- After the above actions, let the soil rest for a couple of weeks.
Selection of seedlings
It should be noted that the seedlings better to choose in the fall, because in that case they will definitely be fresh. In the spring you risk to buy dried saplings with frost-bitten roots, because it is not known how they were stored in winter. The advantage of buying in the fall lies in the fact that you can see the berry of the variety “In Memory of Dombkovskaya” with your own eyes. If you decide to plant grapes in the spring, pay attention to the growing seedlings grown in packages.
It is possible to plant a bush both in the spring, and in the fall. From April to May, one-year-old seedlings that are woody should be planted, and from late May to June - green vegetative plants. In autumn, the grapes are planted from October until the soil freezes. The technology is the same as in spring planting; however, seedlings planted in autumn will need to be more carefully protected from frost.
Planting should be made in the already prepared soil (according to the above tips). So, in the hole, which was previously poured a layer of drainage and humus, you should put a seedling with straightened roots and gently sprinkle with earth. Next, you need to tamp the ground around the seedling and pour it with warm water. It is advisable to mulch the bush with a dark film or mowed grass for better heating.
With the right approach to irrigation and fertilizer, it is possible to achieve faster ripening of the bushes and, subsequently, more extensive yields of berries. It is also important to know how to properly cut the grapes of the “Memory of Dombkowska”.
Moisture charging watering is done in the autumn, after the leaves of the grapes were sheltered for the winter. If the land enters the winter dry, it will be very bad for grapes. If the autumn was rainy, you should not use this type of watering. In the spring, this watering is done after the vines have been tied up.
Vegetation watering is done when the plant needs it most. Thus, the need for such irrigation occurs before the opening of the peephole and during the setting and growth of berries. In the second half of summer, the bushes should not be watered. So, a fortnight before harvesting, it is necessary to stop any watering of the soil. Drainage watering is often used by amateurs in their small vineyards. So, asbestos-cement pipes are buryed along the row (diameter - 100-150 mm, depth - 40-50 cm). The soil from above should remain approximately 10 cm. 10-20 small holes should be drilled from the bottom of the pipe. After the pipe has been installed, the upper end should be closed to avoid trash entering. This type of irrigation is very convenient and effective, because the water immediately goes to the roots of the plant, which has a positive effect on the latter.
About feeding the variety "In memory of Dombkovskaya" should be remembered even when the bush did not wake up. In early spring, while there is still snow, it is necessary to scatter superphosphate in granules (about 40 g per square meter) along the near-stem hole. In this way, we will take care of the proper awakening of the vine. The next feeding should take place in May in the form of nitrogen, which helps the plant to increase its green mass. After the buds are swollen, the vine need to water infusion of chicken manure, because it contains a lot of nitrogen, as well as other useful trace elements.
To prepare the infusion should follow this recipe: 1 part of the liquid substrate should be mixed with two parts of water and left to rest for a week. Next, this solution should be diluted with water at a ratio of 1:10 and water the grapes with the expectation of one liter per plant. After making this fertilizer grapes need to pour plenty of water.
Pruning grapes - an annual event to shorten the perennial branches and annual shoots. To pruning should start in october after leaf fall. So, on the branch that left it, you need to leave only two well-developed and mature branches that are at the base.
The rest without regret needs to be removed. Next of the two branches of the lower need to cut to two buds, and the top - up to 7-15. Thus, we have two vines of different lengths, called the fruit link.
The following spring shoots will grow from the vine as well as from the bitch with the harvest. We formed a long vine so that it would yield a crop (that is, it is the fruit part). A short one should grow two new vines to form a fruit vine next year (growth part).
Spraying against pests and diseases
The variety “In Memory of Dombkovskaya” is not very susceptible to attacks of various fungi and pests, however, it is still afraid of mildew and oidium, therefore it will not be superfluous to spray grapes for the purpose of prevention.
So, mildew helps spraying 2% solution Bordeaux liquid, and in order to prevent the need to spraying 5% solution of copper sulphate. From oidium protect 5% solution of parchment potassium or calcined salt. Also it is worth considering that if the grapes are on the vine for a long time, then there is a danger of wasp attacks.
Features wintering varieties
The variety is also incredibly resistant to frosty winters. Even if you cut the vineyard high, the vine will not die at -28 ° C. Snow also does not interfere with this variety. Of course, it would not be superfluous to use shelter for the winter for the vine, because in this case it will not die even at -30 ° C.
Advantages and disadvantages
Already from the description it is clear that the “Pamyati Dombkovskaya” grape variety is a great option for beginners who want to master the technique of growing grapes. The advantages of the plant weight:
- The harvest is quite abundant compared with other varieties growing to the north (for example, in the Urals).
- The frost resistance of the grapes can not but rejoice, because it does not respond to the lowest possible air temperature (up to -30 ° C).
- Resistance to diseases and pests at a high level. In addition, there is the possibility of processing plants for the prevention and control of diseases already occurring.
- The variety matures very quickly, delighting with tasty and beautiful berries.
- The variety “In Memory of Dombkovskaya” tolerates not only frost, but also drought.
There are no significant deficiencies in the variety. Grapes "Memory Dombkovskaya", judging by the reviews of experienced gardeners, very strong-growing. The vine grows as thick as a finger and matures remarkably. Also note the amazing taste of grapes as an independent product, and its derivatives (compote, juice, wine, etc.).
Summing up, it should be said that “Pamyati Dombkovskaya” grapes are a wonderful variety that is ideal for growing by beginners: it is unpretentious in care, it withstands frosts well and at the same time gives a rich harvest of tasty berries without pits.
Biological variety description
The grapes of “In Memory of Dombkovskaya” are table-sodden. The bush is strong, fast-growing, with a thick and durable vine. It, growing even in the conditions of risky farming by 5 meters, manages to fully mature during the season.
Its dark green carved leaves with long petioles have a barely noticeable edge, similar to cobwebs. Medium sized berries, gathered in large clusters, appear almost black. They mature depending on the climate of a particular area from mid-August to the end of September. And in particularly favorable conditions, the first ripe bunches can please the hosts in early August. The ripe clusters left on a bush do not burst and continue to gain sweetness. And at the end of autumn, slightly sagging in the sun, they become similar to raisins.
These berries have maroon juicy sweet-sour pulp, thin peel covered with a small wax layer. Their taste is very pleasant, and there are no seeds in the grape pulp. When overloading bushes with a crop, the taste of berries may deteriorate those. they become sour or even begin to taste bitter. In addition, they are shrinking.
Flowers, like most hybrid grape varieties, are bisexual in ChBZ.
“In memory of Dombkovskaya” belong to the early ripening varieties, since from the time of bud break to fruit ripening, in his case from 90 to 115 days.
His grape clusters are rather large, their weight is 300-700 g. The sugar content of berries is average (up to a maximum of 20 g per 100 g of pulp).
The first tassels appear already on two-year bushes. And in the fifth season it is already possible to harvest a full-fledged crop - at least 10 kg from a bush, although this is not the limit.
The best load for the variety is about fifty eyes and three dozen green shoots per bush. For him spend a long pruning - up to 10 eyes.
The merits of the variety
“In memory of Dombkovskaya” is a special grape variety intended for cultivation in critical conditions, therefore it has a number of unique properties due to which many specialists in winegrowers know it and appreciate it:
- Frost resistance Under the snow, high pruning vines withstand temperatures up to 28 degrees of frost. And with additional insulation - up to 30 degrees.
- Productivity For its zone it is one of the most reliable and high-yielding grape varieties.
- Disease resistance. This grape is quite tall. Even with the defeat of the leaves of fungal diseases (mildew or oidium) after their spraying the plants are fully restored and continue to bear fruit.
- Drought tolerance - is on average.
- Terms of fruiting - early and stable.
- The ability to adapt to harsh climatic conditions is high. Vine for the short summer season has time to fully mature.
- Fruit taste- pleasantand their color is rich and impressive.
For a sapling choose a place well warmed by the sun, better - next to the southern wall of the house. For each bush allocate an area of one and a half to three meters. And then carry out the following activities:
- Dig holes for bushes one meter deep.
- To ensure good drainage they lay a layer of gravel, and to feed the seedlings - compost or humus.
- In the soil extracted from the pit, add a third of the volume of sand and fall asleep, leaving a recess for the seedling.
- A sapling with straightened roots is placed in a hole, sprinkled with earth, which is then compacted.
- Then it is watered with warm water in such quantity that the earth is well soaked.
- So that the soil is warmed up better by the sun, the near-barred circle is mulched with dark materials.
Description of the variety "In memory of Dombkowska"Grapes "Memory Dombkovskoy" description of the variety. The vigorous shrub has large three-lobed dark green leaves. The vine is long, thick, it has time to fully ripen by the time of shelter. Flowers bisexual.
The Cone of Monte Cristo, Galben Nou and Ladannay also possess the flower hollow.
The cluster has a cylindrical shape, its size is medium or large, and the density is very high. The weight of a cluster of medium size is 300-400 g, and the largest - more than a kilogram.
The berries are medium in size, their shape is slightly oblong, almost rounded. Under the thin blue-black skin with a light whitish bloom, pink, very juicy and sweet flesh. Burgundy-colored grape juice, very pleasant to the taste.
Diseases and pests
Like any grape, ChBZ may be affected by mildew (downy mildew), oidium (true powdery mildew), anthracnose. But most often, the ChBZ suffers from gray rot due to the high density of the bunch.
First signs of failure mildew: yellow oily spots on the leaves, and on the green shoots spots of gray-brown color.
How to fight?
As a preventive measure, in spring, before the buds swell, the bushes and soil are treated with 5% solution of copper sulphate.
If the bushes have already been affected earlier, spray with a 1-2% solution of Bordeaux liquid:
- first time - shoots 15–20 cm long,
- the second - after flowering bush.
- non-copper organic substitutes for Bordeaux liquid can be used
Affected oidimum bushes look as if they were showered with ashes. Leaves on both sides are covered with gray bloom. The plant smells like spoiled fish.
How to fight:
- 0.05% potassium permanganate solution,
- 0.2% Fundazole,
- 0.5% soda ash,
- 0.03% byleton
Anthracosis manifested in the form of grayish with brown rim spots on the leaves. In the process of destruction on the spot spots are formed holes. The disease is most dangerous for inflorescences.
How to fight:
- as a preventive measure in early spring spraying with 8% solution of ferrous sulfate.
- in the case of manifestation of the disease, triple treatment (at the stage of escape, before flowering and after) with a solution of any of the preparations:
- boricide (0.4%),
- copper oxychloride (0.5%),
- Zineb (0.4%).
Gray rot appears as small watery spots on the berries. In a rainy autumn, you can lose the entire crop, as the moisture on the surface of the berries contributes to the development of the disease.
How to fight:
- during the rest period, treat the vine with a 5% solution of copper sulphate.
- effectively alternating the treatment with a 0.7% solution of soda and 1% green soap.
Do not forget about such common and dangerous diseases of grapes as bacterial cancer, chlorosis, bacteriosis, rubella. In time taken preventive measures will secure your plants.
In addition to diseases, birds, which simply peck up berries and wasps, eating flesh, cause enormous harm to the PWZ crop.
Having flown into such a trap, the sweet tooth will not be able to escape to freedom.
Do not think that grapes are a purely southern and capricious culture. Sunny, suitable climate, moderate humidity, earth and caring hands - this is what this berry needs.
And not capricious Variety Memory Dombkovskoy be sure to reward caring for a bountiful harvest.
How and when was it withdrawn?
The grapes in memory of Dombkovskaya or ChBZ (black seedless winter-hardy) were bred in 1983 by the domestic amateur winemaker F. Shatilovym by breeding varieties Dawn of the North and Kishmish unique. The result is a unique variety of culture, resistant to adverse climate and not having seeds in the pulp. In the state register of Russia was included in 1990.
Grapes of this variety belongs to the technical direction, but is actively used for the manufacture of raisins. Was positively received by winegrowers, is a promising variety for cultivation in the northern regions.
The variety has a high yield, which is not typical for grapes bred for use in regions with a poor climate. When grown on a trellis and the correct shaping of a bush from one plant, up to 20 kg of fruits can be obtained.
Productivity depends on the season, as well as proper care of planting. For varieties Memory Dombkovskaya recommended long pruning on 10 eyes.
During the harvest, it is necessary to take into account that the berries of this variety are very soft and quickly crumple under mechanical action. Poorly tolerate long-term storage, so they are recommended to be immediately used for the manufacture of blanks. Grapes belong to the technical grade, but is also used for the preparation of raisins.
Suitable region and climate
ChBZ grape variety is one of the most cold-resistant grape varieties of domestic breeding. Able to withstand up to -27 o C, resistant to sudden temperature changes.
Recommended for cultivation in regions with adverse climatic conditions, is promising for viticulture in the northern regions. However, it is suitable for cultivation in the southern vineyards. Full maturity is possible in a short summer, the lack of sunlight does not affect the yields.
Variety Memory Dombkovskoy appreciated the growers of the northern regions.
He is able to give a stable and high yield even under adverse conditions. It is an unpretentious variety, suitable for novice gardeners. Because of the characteristics of the bush, it can be used to decorate the site. Fruits, despite the technical affiliation of the variety, can be used not only for making wine, but also blanks, raisins.
This kind of grape has its drawbacks. In the rainy season, there is a chance of polishing berries, as well as the deterioration of the presentation of the bunch. Variety refers to seedless, but in the pulp there can be reduced bones.
Grapes of this variety are best planted in a well-lit place with protection from the wind. The recommended landing site is the southwest or southeast wall of the site, or a fence. This will not only protect the bushes from drafts and gusts of wind, but also slightly increase the temperature.
The soil should be fertile and light, the best option is black soil, loam. When planted in dense soil, grapes develop worse and the yield is reduced. WITH
It is necessary to pay special attention to the level of groundwater, if they are high, then a drainage system must be installed. For industrial cultivation is required to analyze the soil, it is not recommended to plant a culture in acidic soil.
The Dombkovskaya vines are planted in the spring, beginning in the second half of April, or in the fall before the first frost. Cuttings can be prepared independently or bought in the nursery.
A few days before planting, they are soaked in water, and then transferred to a container with a solution of a biostimulator. Planting material is recommended during the day in sunny and windless weather.
Planting technology of grapes:
- Dig the site to the depth of the spade bayonet and add complex fertilizer, and organic matter (mullein, bird droppings or peat) is recommended for infertile soils.
- Dig up the planting holes up to 40 cm in depth. The optimal size is 80x80 cm. Lay a drainage layer up to 5 cm in the bottom, it is better to use claydite or crushed stone as it.
- Pour 7-10 cm of fertile substrate on the prepared drainage system, and then install a cutting in it strictly at right angles. Top sapling need to fall asleep and rammed.
- After planting a young bush must be watered with warm water at the rate of up to 10 liters per cutting. Even at this stage, it is desirable to carry out mulching.
The Dombkovskaya variety grape variety is self-fertile, therefore pollinating is not required, but is recommended for obtaining greater yield. Starting from the second year a sprawling bush is formed, the plants should be planted at intervals of at least 1.5 meters from each other.
Proper care is an important requirement for maintaining healthy grapes and producing a rich harvest. Fruiting begins only in 3 years, but after planting, you can begin to work.
Features care for planting:
- Watering should be carried out starting from the second week after planting the cuttings. It is best to water the plants through a special tube, one end of which is deepened next to the roots, and run through the second one. In its absence, watering is carried out in the traditional way. Water should be warm, the procedure should be carried out as the soil dries out, at least 1 time in 2 weeks.
- Feeding is carried out 2-3 times per season. In the first year it is desirable to use organic matter, which has a positive effect on the formation of young shoots. As a fertilizer, you can use a solution of mullein, humus or peat. In areas with poor soil it is necessary to additionally feed the plants with complex mineral fertilizer with a high nitrogen content at least 1 time per season.
- In early spring, they carry out a complex treatment of the vineyard from fungal diseases (mildew, oidium and anthracnose). It is recommended to use synthetic systemic fungicides. Treatment from pests in the first year is carried out only when malicious insects are detected.
- For this variety, it is desirable to carry out a long pruning of at least 10 eyes. The formation of the bush should be carried out in the fall after the leaves fall.
In the first year should be installed trellis, necessary for mounting the antennae of the vine and protection from the wind. Most growers use U-shaped supports. Shelter for the winter for this variety is not necessary, but young plants should be sheltered in order to avoid death during frost, especially in the regions of high-risk agriculture. To do this, use spruce, straw or agrofibre.
The grapes of the Memory variety Dombkowska have a high resistance to diseases typical of the culture. At non-observance of technology of cultivation and leaving there is a risk of infection with mildew.
In order to avoid infection, it is necessary to carry out preventive treatment with fungicides (Topaz, copper sulphate, Bordeaux mixture or Skor) in a timely manner.
Pests infect the plant rarely, there is almost no threat of phylloxera, but when grown in some areas there is a risk of the appearance of a grape mite.
Upon detection of characteristic signs (white spots on the leaves, drying of the vegetative parts, and others), the entire area should be treated with a contact insecticide, and also all affected parts of the plant should be removed.
History of creation and removal
Enthusiast Fyodor Ilich Shatilov from Orenburg brought this variety 30 years ago.
It was named in honor of Yanina Dombkowska, who was an assistant in creating a new kind of grapes. Other name - black seedless winter hardy (cbz) , turned out by selection of the Dawn of the North and Kishmish unique.
Together with his colleague Shatilov sent to Chelyabinsk a huge number of seedlings for cultivation. After that, gardeners got a crop in an incredible amount.
For a large load, the variety requires good nutrition.
- Unable to withstand a large number of clusters, resulting in a decrease in berries.
- In case of unfavorable care and re-singing, it may pea.
The variety must grow in soil saturated with all the necessary nutrients.
Standard planting pit for grapes.
If this is not enough, it is necessary to periodically feed the soil. The soil for planting can be loamy or chernozem, but without excessive moisture.
Before planting, prepare the soil with the following activities:
- Dig a hole of 1 * 1 * 1 meter in size with a distance of about 2 meters from buildings or another hole.
- Arrange the drainage of gravel or rubble.
- Fill with humus potassium phosphate fertilizer.
- Set the peg in the middle of the vine garter.
- Let the soil stand for 1-2 weeks.
The main criterion for landing is the right place. Planting is recommended on the south side of the plot so that the grapes receive the maximum amount of sunlight.
In northern latitudes, it is better to plant grapes along a high wall.
Cuttings need to pick up in the fall, then they will be the most fresh. In the springtime they become a bit dry, and the roots can be frost-bitten. But also in the autumn period there is a chance to see the berry in order to assess the quality of the acquired cutting. When planting in the spring, you can use seedlings grown in packages.
Landing dates vary widely.. In the autumn you need to plant in the period from October to November, and in the spring from April to June, depending on the condition of the seedling. In the cold after planting the stalk must be covered so that it does not suffer from frost.
Planting of grapes is carried out in the previously prepared soil. Roots should be straightened on the ground and sprinkled on top of the ground. After that, the earth is gently rammed and watered with warm water in an amount 10–20 liters . To heat the soil, you can use mowed grass or hay, laid with mulching.
Features grape care
To obtain a good harvest, timely watering, pruning and fertilizer should be carried out in memory of Dombkovskaya.
The cultivation of this grape is not a troublemaking business, since the variety was originally intended for cultivation in critical conditions.
The first watering is carried out before winter, after hiding the grapes.. If this is not done, the quality of the harvest may noticeably deteriorate. During the rainy season, water recharge irrigation is not carried out so as not to exceed the soil moisture. With the arrival of spring, the grapes need to be watered after the garter. The main watering is necessary before the formation of the eyes and before the ripening of the berries. From July-August watering is not carried out, so as not to reduce the yield and not worsen the quality of berries.
The use of drainage irrigation will be effective in small vineyards.
Landing pit with drainage irrigation.
Asbestos-cement pipes with a diameter up to 150 mm to a depth of 10–20 cm are driven in along the rows, the bottom of the pipe should be with holes. To prevent debris from entering the pipe, it is tightly closed.. Such irrigation is much more effective, since the water goes directly to the roots of the grapes, which contributes to the better development of the root system and the growth of the bush.
