  • fruiting coefficient - 0.8 (on 10 shoots of 8 bunches);
  • fruiting coefficient - 1.2 (on 10 fruitful shoots of 12 clusters);
  • 65% of fruitful shoots (65 shoots out of 100 give inflorescences).

Did you know? Some vine bushes grow up to 100 years. It is interesting that the more the bush lives, the greater the yield it brings each year.

Grape application

Sugar content of berries is 16–17% with an acidity of 6 g / 1 l, which makes this grape an excellent table variety for universal use. It lies well, so it can be harvested fresh. It makes a wonderful juice, as well as raisins. You can use this grape to make a weak wine.

Landing time

Planting of cuttings is carried out both in spring and in autumn. Spring planting is best done in April-May. The shank should be annual and lignified. If it is green and growing, then it is better to start planting in May-June. In autumn, grapes are planted to frost on the soil.

Care for the grape of Negrul memory

That is why watering should be monitored closely. It should be plentiful before budding, after flowering and during the ripening of the bunch.

Important! It is necessary to completely stop watering the plant a month before the harvest.

Top dressing

In order for more fruit buds to form on the vine in spring, in the fall you need to fertilize the plant with superphosphates. They will also help to increase the sweetness of berries, accelerate their ripening, and also facilitate the wintering of the plant. To strengthen the immunity of the bush, you need to make potassium top dressing. It is advisable to make any top dressing along with watering.

Shaping and trimming

If the grapes are grown in areas with warm winters, it is better to form it in a two-armed cordon (the vertical part is no more than 80 cm, and the two vines diverge in different directions and give young shoots). Where the plant requires shelter for the winter, the vertical part is not formed so that the vines can be easily bent to the ground without causing damage to them. The bush is not trimmed very much.

The whole procedure can be divided into two stages:

  1. Autumn pruning (preliminary) - after the discharge of foliage.
  2. Spring pruning (final) - removing dead buds.

For these two prunings, the vine should be shortened by 4–5 eyes, but so that no more than 45–50 eyes are left on the whole bush, otherwise this will heavily load the plant. Trimming is carried out from top to bottom.

Important! It is advisable to leave more lignified shoots, since the best brushes are formed on them.

Features of protection against cold in the winter

If you need to prepare a young seedling for winter, then you can cover it with a plastic bottle, making holes for ventilation in it. Adult bushes are tied with burlap or covering material, and then mulched (peat, needles). Before frosts, abundant irrigation and loosening of the soil are mandatory.

Diseases and Pests
