According to the table, the fruiting factor is 1.1.
Such grapes do not grow, they have small light green foliage, which is not much on the vine.
Ripening period
Druzhba grapes are early ripening varieties. The bunches begin to ripen already on the 115th day from the moment the buds swell.
By the end of August, gardeners are harvesting. If the berries ripen later than the specified time, it means that the formation of bunches was poorly followed, and there is an overload of the bushes with fruits.

Yield
The grape yield is 80 centners per hectare.
Growing features
Light soils are ideal for planting. Either loam or sandy soil can be used.
In a bush, the main root grows deeply into the soil, therefore, with a high location of groundwater, root rot appears.
The landing site must be on a sunny and calm side, away from trees and tall buildings.
Landing
Druzhba grape cuttings take root well in trenches or holes. In the south of the country, planting is carried out in the fall.
If you plan to plant the territory in the central part, then it is better to do it in the spring. Before the onset of cold weather, the seedlings will be able not only to take root, but also to prepare for the cold weather.
The landing pit is prepared in advance. Organic fertilizers are placed on its bottom and everything is covered with fertile soil.
If foliage has already appeared on the seedling, then it is planted only after the threat of night frosts disappears. As a rule, this is the end of April. Cuttings without foliage can be planted in the ground from March.
Pollination
Since bisexual flowers appear on the bush, it is not required to additionally pollinate the variety.
Pruning
Pruning is necessary, 6-8 eyes are left on the vine. But up to 3 years of age, only sanitary pruning is carried out. After this period, the load on one bush should be no more than 35 eyes.
Frozen vine and heavily damaged vine must be removed. Such shoots are cut in the spring.
Watering
It is worth watering the cuttings immediately after planting and then with the beginning of the growing season once every two weeks. With the appearance of ovaries, the amount of water is halved.
The last watering is done a month before picking berries.
Top dressing
Grape bushes need to be fed at least three times per season. Bird droppings are ideal for spring. It is preliminarily dissolved in water.
The procedure is repeated two weeks later, you can use superphosphate.
Nitroammofosk is necessary during the period when ovaries are formed on the bush.
Frost resistance and the need for shelter
Friendship is able to withstand temperatures down to -23 ° C. Such frost resistance is at a high level.
If grapes are grown in northern regions, they must be covered. In the south of our country, it is enough just to huddle the bushes for the winter or use partial shelter.
Diseases and pests
Friendship is resistant to mildew, but susceptible to root and leaf phylloxera. In the absence of any treatment, it can get sick with gray rot or powdery mildew.
Processing is carried out at least once a season. It is best to use Bordeaux liquid.
If a grape is exposed to any disease or insect, this always affects its appearance.
