  • possibility of using variety for landscaping.

But Alpha also has disadvantages:

  • poor disease resistance;
  • low tasting score;
  • prone to overgrowth;
  • need for constant pinching.

Selection and planting of seedlings

Alpha is unpretentious in care. But to get a harvest, you need to follow the recommendations:

  1. He althy rooted cuttings are suitable for planting. The root system, underground and ground parts should be well developed.
  2. You can use any grape variety as a rootstock. For the scion, a he althy cutting of Alpha is taken. It is recommended to graft in any convenient way (split, overhead).
  3. The landing site should be sunny, protected from the north and northeast winds. Grapes should be planted near the southern and southwestern walls of suburban buildings. It is recommended to take into account the size of the bush: it is required to step back from the walls 2.5-3 m.
  4. The grower must take care of the support for the vine in advance. The plant overloads itself with fruits. Untied stems break, the crop is lost.
  5. The depth of groundwater at the site is 3-4 m. Grapes do not tolerate waterlogging of the soil. To prevent wetting and rotting of the root system, drainage is required before planting. To do this, it is necessary to grind crushed stone, brick, tile and pour a layer of 7-10 cm on the bottom of the planting hole. This simple measure will prevent stagnation of water at the roots.
  6. Soil variety prefers fertile, loose, with a neutral or slightly alkaline reaction. It is recommended to deoxidize acidic by adding lime (1 liter per square meter). To obtain a permeable soil, add perlite, neutral peat, sand.
  7. Alpha takes root well when planted in early spring or mid-autumn.

It is recommended to buy grapes in nurseries or specialized stores: this way you can avoid disappointment.

Features of care

  1. Alpha is responsive to watering. The soil should be moistened during flowering and the formation of ovaries. It is recommended to stop watering during the fruit ripening period: excessive soil moisture leads to cracking of the berries.
  2. It is recommended to combine watering with top dressing. In the spring, be sure to apply nitrogen fertilizers. In spring and autumn - mineral complexes.
  3. Very vigorous variety. It needs to be trimmed to evenly lighten the maturing brushes. Be sure to carry out chipping and pinching during the ripening period.
  4. Preparing for winter is impossible without shaping pruning. All immature vines (they are green) should be removed. Then leave a replacement shoot (2 eyes) and above it a fruiting vine (6-7 eyes). Up to 6 such segments are required on the main vine.

Grapes winter well without shelter. To protect the root system, it is recommended to mulch the near-trunk circle with sawdust with a layer of 15 cm.

About diseases and pests
