Not many varieties of grapes, which, really, well tolerate harsh winters. But the variety Olenyevsky refers precisely to such. In this article, consider the history of variety, its feature, fruit, agrotechnical moments, frost resistance and storage time.
History of removal
Technical grape variety Olenyevsky was removed by the breeders of Potapenko l. NS. and Potapenko A. AND. In 1986, in the Nizhny Volzhsky Research Institute. Two grades of Amur grapes were taken to remove the hybrid. As a result, there was a medium technical grade, which was released only in 1991.
Other variety names – Olenyevsky Black, Black Potapenko, Olenyevsky Potapenko.
As mentioned earlier, the variety of medium, is used mainly for winemaking and juice.
Bushes are large, powerful and empty. Vines usually go out and make up, even thunder and low weight, branches are still leaving towards Earth. Therefore, it is necessary to install the pillar support system. Soothes in the outlet are very close to each other, so growing, they form a tight wall. Rusted brown vine, there is peeling and down.
Medium-sized leaves, small, cross section barely noticeable. The blades are practically absent, in shape resembles a wedge-shaped. The upper surface is smooth, on the reverse side there are pork and terrain. In bloom bright green. By autumn before falling out the leaves yellow.

Rounded conical berries. Tint deep black, present gloss and wax. The weight of the berry is 1-2 g, are considered a small variety. The flesh is juicy, fleshy, because of the peel stained in black. Seeds a little, in size small.
Suitable only for machining.
Taste simple, no impurities. Good ratio of sugar and acidity.
Many gardeners celebrate good and stable yield.
Selecting planting material
Gardeners with experience recommend newcomers to take cuttings and seedlings for those who made them from their vine and is engaged in the production of such material professionally.
You can evaluate the quality that cuts a small amount of bark. When growing a bush from a cutting and compliance with agrotechnology rules, the survival rate is about 90%, high quality plants are practically guaranteed. There is the ability to control the development of grapes at all stages.
Under the compliance with the Rules of Agrotechnology, the survival rate is about 100%. Saplings must be healthy. Pay attention to the absence of fuses, growths and other signs of diseases.
Features of cultivation
Saplings can be planted in open ground in both the spring and autumn. This variety has good wintering indicators, so you should not wait for the spring for landing.
It is necessary to choose the right place to land. It should be a sunny side of the site, better on a small elevation. Earth must be loose, sandy and sublinous. If there is a lot of clay on the selected plot, it is better to remove it and bring a new land.
Before landing, it is worth over with useful minerals and humus. This will update the land, and it will be saturated with the useful properties that will later give to seedlings. After popople, the land is abundantly moisturized and leave the week for two weeks.
Grapes should not be planted in the place where water accumulates or swamp. Roots from this variety do not tolerate too much moisture.
Before planting seedlings, you need to dig up the wells and think about the system of the chopler. This is done immediately in order to properly suspend the sharpening shoots after a while.
The size of the hole should be like this: 0.8 m in depth, in diameter 0.5 m. Drainage from broken brick or pebbles is laid out onto the bottom, over the small layer of fresh fertile land along with minerals rich in nitrogen. After that, seedlings are planted. It must be healthy, the roots must be strong, have 2-3 kidneys and 3 escapes.
Losing a young escape stands neatly, gradually falling asleep the branch of the earth. Earth must be ragged. Above the ground level should leave the root neck for 2-4 cm. Richly shed a bushes with water. Optionally, it is possible to inspire the land around the bushes.
In order to 3 years old, the vine gives a signal harvest, it is necessary to take into account the set of factors – from the type of soil on the plot to the nearby plants.The best time for landing most varieties – autumn, and in the cold regions, preparations for landing start in August. Saplings are transferred to the ground at the end of September or in 1 decade of October. For autumn landing, only plants with ridiculous vines are suitable, with a developed root system and with 8-10 eyes.Tips for beginners will help to figure out the optimal schemes for the location of seedlings and cuttings, as well as in other subtleties of this process.
Type of soil
Grapes grown on sand, black earth and clay soils. For each of the options for the composition of the soil, the preparation process will noticeably differ.
Planting vegetative saplings
The basic rules are the same for weird and vegetable seedlings. Vegetable call seedlings obtained by a greenhouse.

All trimming are carried out with a sharp secateur, and all sections are processed by Garden Wara.
So that the berries are large and juicy, it is necessary to organize a full watering and feeding. All standards need to be adjusted to weather conditions and the rate of evaporation of fluid.
With a frequent watering scheme, the moisturizing is recommended once every two weeks (that is, twice a month during flowering and the appearance of berries) so much so that the land is impregnated by 50 cm deep into the plant so that the plant does not switch to surface (dewn) roots. This amount can be reduced if the straw is mulching.
With a rare watering scheme, choosing the age and time of ripening grapes, you can use the standards presented in the table in another article.
