The correct planting of the plant, as well as the subsequent care, are very important factors for obtaining a decent harvest of tasty berries. This variety has a very good degree of hardiness, including adaptability when planting. Such grapes, as a rule, are planted in the spring, starting from the last days of March, ending in June. Many gardeners prefer autumn planting; for this, the period from October to November is suitable.
To begin with, you need to choose the right sweat site for planting future grapes. The ground should be well lit, and an important factor is reliable protection from drafts and gusts of wind. Groundwater should not be located too close to the surface, as a rule, it is about two meters. If the groundwater is above this indicator, then it is necessary to lay a drainage layer. It is best to choose the southwest exposure for this variety.
It is necessary to prepare material for planting. As a rule, growers use cuttings for these purposes. This variety has a very good property, it grows well with the stock. Young plants must be hardened without fail, and you should not neglect the activities that are shown for grafting.
For this propagation method, it is necessary to choose shoots that are located in close proximity to the soil level. Before planting seedlings in the ground, they must be soaked in water. It is necessary to do this in order for the plant to take root better, and the root system to take root and develop better. Grapes are not very picky about the composition of the soil, but there should be a lot of nutrients in the soil. It is imperative to add sand to the soil, especially for too heavy soil. Do not overdo it with moistening the ground just before planting a plant, for this reason, planting plants after rainy weather is not worth it.
As for the size of the planting pits, in the case of fertile soils, a size of eighty centimeters is sufficient. If sand prevails, then the depth should be at least one meter. It is necessary to maintain a distance of one and a half meters between the planting pits. There should be at least two meters between the rows. It is worth noting that with a greater depth of the planting hole, rooting of young plants is better.
Planting holes must be prepared in advance. If you plant plants in the fall, then prepare the pits in the summer, but if planting is carried out in the spring, then the pits are prepared in the fall.This is necessary in order for the soil to settle down. At the bottom of each pit, it is necessary to lay drainage, after which there is a layer of humus and only then, finally, soil. The humus must be mixed with the soil. A peg must be installed in the center of the landing hole, it will serve as a support. Plants need to be lowered to the level of the root collar, then covered with soil.
After that, the planted plants must be well watered, and a mulching layer must also be laid. Young seedlings require shelter for the winter, as they are still too weak to withstand low temperatures. In the first year after you have planted the plant, there will likely be no harvest. During this period, the plant still takes root, takes root in a new place. Although this variety is not a very whimsical culture, you need to know about some of the care features.

This is especially true when the winter was snowless and there was too little rain in the spring. In the following months, the plants should be watered weekly. For this, it is better to choose early morning or evening. As a rule, there are one to two buckets of water per bush. The water should not be too cold, it must be defended for at least a day. Sprinkling and spraying are not suitable for this, watering must be carried out at the root of the plants. For an adult plant, more water is required, one shrub requires two to four buckets of water.
Top dressing, pruning of grape varieties Alpha
To get a good harvest, you need to periodically apply top dressing. Saplings of this variety grow quite actively. During this period, it is necessary to make additional food.

They use the infusion of bird droppings, but it is worth remembering that it must be well bred. For the same purposes, use herbal infusion, as well as ash infusion.
Some farmers use purchased chemicals such as Biovit, Optim-humus, Vermistim and others. It is imperative to use such funds in accordance with the instructions.
It is also necessary to prune plants and remove unnecessary stepsons. This procedure can be carried out throughout the summer. It is necessary to shorten the shoots to a length of eight to ten eyes. This measure cannot be neglected, as the bush will begin to thicken strongly.
It is also necessary to carry out preventive and therapeutic measures against diseases and harmful insects. Diseases of fungal origin practically do not threaten this variety, and as for other diseases and harmful insects, they can cause considerable damage to your grape plantings.

To do this, you can use Nitrafen or Preparation 30. If you do not want to once again add chemistry to your vineyards, then this pest can be removed by hand, but this procedure will need to be carried out often.
- Wasps. These insects are very fond of sweet berries. The main harm that wasps do is in damaged areas on the fruits. It is there that harmful bacteria can multiply, due to which the berry begins to rot.Sweet liquid traps can be used to control these insects; insecticides are also suitable for this purpose.
As for the diseases that affect the Alpha variety, fortunately, there are not too many of them. First of all, grape vines can be affected by powdery mildew, various rot, chlorosis. It is quite difficult to overcome such diseases, for this reason it is necessary to regularly spray the plants for the purpose of prevention. Sometimes plants can be attacked by anthracnose.
