America's grapes in Russia are grown without difficulty: it is resistant to diseases and low temperatures. This culture can withstand -34 ° C.
The most comfortable conditions in the Russian Federation for the following American grape varieties:
- Berlandieri;

Labrusca and Monticola varieties
These varieties are similar to Rupetris. The difference is the liana-like type of shoot. The survival rate of the planting material is poor. In Russia, both species are used for vaccination.

Planting and leaving
Harvesting of planting material is carried out in the Spring period. For planting, shoots are used, on which up to 7 eyes are located.The diameter of the vine is up to 1.1 cm, the length is up to 40 cm. The healthier the seedling, the better the harvest.
At the first pruning in the spring, up to 8 buds are left. Within 2 months after planting, they are engaged in systematic loosening and watering. For American breeding, the most dangerous disease is powdery mildew - it is imperative to carry out prophylaxis against it.
If the climate is arid, mulching is done. During flowering, a small number of flowers are cut off: this increases the size of the bunch by 80%. Bushes are constantly examined in order to be able to detect disease or pest damage in time.
Cold-resistant varieties
This group of American selection is the most resistant to subzero temperatures.
Variety | Color | Berry weight | Bunch weight | Sugar | Maturation |
Seneca | White | up to 5 g | up to 300 g | 18% | Early autumn |
Ontario | White | up to 3.5 g | up to 250 g | 20% | Early autumn |
Buffalo | Blue, purple | up to 5 g | up to 500 g | 21% | Early autumn |
Vulture | Dark blue | up to 4 g | up to 300 g | 25% | Early autumn |
Bluebell | Dark blue | up to 3.5 g | up to 300 g | 19% | Early autumn |
Conclusion
There are more than 25 varieties of grapes from America, including raisin hybrids. All of them are cold-resistant and undemanding to care conditions. The technical features of planting are the same as those of domestic varieties.
