Growing grapes in a greenhouse

The climatic conditions of different regions do not always allow the cultivation of heat-loving crops, especially such as grapes. Here, low average daily temperatures in the warm season, as well as insufficient daylight hours, affect. In this case, it is recommended to use modern techniques that allow you to grow a southern plant in greenhouses. Thanks to many years of practice of experienced breeders, greenhouse varieties are not inferior to traditional varieties in terms of quality.

What varieties are right?

Perfect technology allows you to grow grapes on any personal plot, using a greenhouse for this purpose. By showing patience and applying some knowledge, you can achieve a high result in obtaining a bountiful harvest from the selected crop. Closed structures will not only increase the length of the season by hiding plants from spring frosts, but also protect them from such unpleasant influences as hail.

Before planting grapes in a greenhouse, you should choose the variety that best suits the wishes of the customer. Most often, such attempts are made in temperate zones, where the following varieties have proven themselves well:

  • “Michurinsky”;
  • “Early Northern”;
  • “Bulgaria”;
  • “Russian currant”;
  • Moscow Stable.

Polycarbonate greenhouses will be an excellent solution for planting the presented varieties in early spring. Each of the new varieties grows and develops excellently in a closed space with proper care at the required temperature and sufficient light.

Landing

For planting a vine, first of all, prepare the soil. Here it is best to use a compost mixture prepared according to a specific recipe.

  • A little superphosphate and wood ash enriched with potassium are added to a portion of humus.
  • The resulting substance is diluted 50/50 with the soil from the greenhouse.
  • Planting holes are dug to a depth of 0,5 m, filled with compost mixture, and seedlings are planted.
  • When planting, it is important to carefully spread the root system, place the seedling in a moistened hole, press it with soil, and water it abundantly.

Planting cuttings in the greenhouse can be done already in the first days of March. During this period, daylight continues for enough time for plants, and the external average daily air temperature does not reach dangerous values. In greenhouse equipment, it is important to include support frames for which the developing vine will cling.

It should be remembered that bunches of grapes must be kept in limbo to avoid premature decay.

Care

To obtain a quality crop in greenhouse conditions, plants must receive proper care. The most important condition that allows the plant to timely move to the next phase of development, without reducing the growth rate, is the temperature regime.

This means that the air temperature in the greenhouse must meet certain standards at each stage of plant development. There are frameworks for each cycle, which include:

  • period of kidney development;
  • time of active growth of the vine;
  • flowering period;
  • stage of fruit formation;
  • maturation period.

For each intermediate stage, there are optimal temperature limits that allow the plant to feel comfortable. Too high or too low a temperature will equally badly affect the growth of the culture. The result can be a late harvest, requiring additional costs. This means that it is important not only to insulate the greenhouse, but also to equip it with blackout in the form of a special mesh. This precaution will prevent the sun’s rays from heating up the interior too much.

In addition, an effective ventilation system must be provided to allow ventilation of the greenhouse at high daytime temperatures. For this purpose, opening sashes are used to fill the space with fresh air in a natural way. This procedure will allow not only to supply the plants with the necessary amount of oxygen, but also to comply with the required temperature regime.

One of the important stages of caring for grapes is stepchildren.. The procedure is reduced to the timely removal of underdeveloped shoots, diseased leaves and non-pollinated inflorescences. Thus, the root system will not spend a valuable energy resource on the maintenance of useless elements. On the other hand, all the forces of the plant will be directed to the development of healthy shoots and full-fledged fruits.

The flowering period of grapes, as a rule, occurs in the second half of May. Most greenhouse varieties are self-pollinating, but some crops still need outside help. This point must be clarified at the time of purchase. Pollinating the grape color is quite simple: you need to methodically shake the branches with inflorescences.

An actively developing vine can fight off an artificial support, in which case it must be fixed forcibly. Barren shoots are subject to pruning, they are shortened to the position of the fifth leaf. If these are stepchildren of the second order, they can be shortened to the location of the first sheet. With abundant fruiting, green grapes should also be thinned out. Internal formations that are poorly adapted to full development due to an unfortunate location are subject to removal.

КWhen the crop is harvested, and the leaf has flown around, it is time for autumn pruning. During this period, all long processes are removed to the location of the first kidney. In this case, the central stems are shortened by 2/3 of the length. The vine is unfastened from the support, spread over the soil and covered with hay, straw or sawdust so that it does not die from frost in winter.

If the roof in the greenhouse has a removable structure, it is removed for the winter. Sheltered grapes overwinter excellently under the snow.
