When to open grapes in the spring?

Grapes have always been considered to be a southern plant, for this reason, on the territory of the middle strip it began to cultivate not so long ago. As a result, many beginner grapes appeared, which have not yet accumulated enough experience. One of the most asked questions is due to the period in which the plant should be opened. And many are interested in what events are recommended immediately after removing insulating cover.

Of course, the first thing you need to do after the snow is to establish the exact time suitable for the release of the vine and the launch of the vegetation mechanism.

Suitable temperature

The experimental way has long been found that while the kidney of grapes are in sleeping condition, they are able to transfer freezes to -4 degrees Celsius. However, if the kidney has already awakened, it will definitely die even with a slight frost in -1 degrees. This biological feature of culture requires special attention of the gardener in early spring, when weather conditions remain changeable. First of all, it is necessary to take into account the average daily indicators when the daily air temperature is noticeably different from the night. Next, the following circumstances are taken into account:

  • The minimum air temperature, which is capable of making a grape vine is -5 degrees Celsius;

  • If the frost is more, it will end the frustration of shoots;

  • Worst of all grapes tolerate temperature fluctuations;

  • The most favorable conditions occur when the daily air temperature reaches a value of 8-10 degrees of heat, and the night – not falling below zero.

Despite the spring snow, which continues to linger in some areas, the plants are gradually starting to revive. To open grapes in the spring, it is not recommended to repel from a specific date. First of all, it is necessary to make sure that the threat of night frosts has already passed. To this time it is better to keep patience.

When to disclose in different regions?

When it becomes clear that stable positive temperatures have already been installed, and the soil begins to gradually push, the vine can open. For each region, this time comes at a certain time. For the southern regions, the time for removal of insulation comes in early April. Opening in the middle lane or in the Volga region is closer to the beginning of May. In Belarus and regions located, the nine moderate belt should wait for the arrival of May. After winter shelters, Lose continues to remain in sleep and requires a number of preventive measures.

How to open?

First of all, protective covers are removed from the vine – it can be mats from insulation, boards, film or rubberoid trimming. If the vine is cheered for the winter, it should be careful and clean from soil. It will be more reliable if this procedure is embarrassed with the complete confidence of the absence of night frosts.

Nevertheless it is also not recommended to delay, because if the vine remains closed after the obvious warming, it can snatch.

It will be much better if the winter shelter is removed into one of the sunny days, and for the night some time to continue to strengthen. This will allow grapes gradually dry, moreover, not suffer from likely night cooling.

Protection during freezes

Unexpected frosts are the greatest threat to grapes. To protect the plants from the likely cooling, the framework of metal arcs or wooden rivers is installed above it, which is covered with nonwoven material. Agrotex is best suited, you can also use spanbond. Such cover will ensure the necessary ventilation and protect against sudden temperature drops.

Stripping grapes with polyethylene film is not recommended, because it does not miss evaporation and can cause kidney or shoots. In addition, the increased humidity in greenhouse conditions will provoke the development of mold or fungal organisms. In any case, in the afternoon it is necessary to provide abundant ventilation.

Coating from nonwovens protects the vine from unexpected cooling to -3 degree, When risk reduction of temperature below this mark, it is recommended to apply an additional insulation. The ground around the grapes during the day it is necessary to moisturize moderately. These measures will help preserve the viability of the plant in conditions of changeable weather.

What to do after disclosure?

In the spring, when grapes are revealed after the winter, he is given well to dry. But the high humidity at this moment creates certain risks of the development of diseases and the activation of parasites. To avoid negative consequences, it is necessary to adopt a number of preventive precautions. In addition, the vine should be prepared by the period of active development.


Usually the vine is never tied up immediately after removing the winter bedspread. For some time the plant should ride a little. So straightened shoots unfolded on a stationary frame and give them to heaven 3-4 days. The garter in the spring is called dry, because the procedure is carried out for the sleeping plant.

Choosing an optimal vertical, diagonal or horizontal location. Grape shoots are fixed in a fixed state. If necessary, support should be updated, or make additional wire testers.


After fully drying, triggering young shoots, as well as processes that did not pass the contamination procedure in the fall. This event occurs according to certain rules.

  • First of all, all unnecessary processes that could dry, break or create an excessive part.

  • The thickness of the vine at the base, the longer the processes should be left.

  • Scroll is carried out by a sharp tool between urins or slightly above eye.

  • Fruit links should be formed from the vine that has received good development.

  • For fruiting, one-year vine is suitable, the cut thickness of which reaches from 6 to 12 mm.

  • Fragments of vines are subject to removal, which fruits last year. Of the two processes located on the bitch of replacement, leave the internal escape.

Soil processing

Spring tillage around grapes start with weeding, bursting of the soil and, by the possibility of mulching with an organic. It is embarrassed after the soil will dry, and at the end of May this procedure should be repeated. Spring watering should be very moderate not to create favorable conditions for the development of fungi. Excessively wet soil can cause root rotting, as well as it is much faster freezes.

Chemical treatment

After the grape trimming is made, it is sprayed with a chemical composition, which is capable of preventing the development of fungi and harmful insects. For this purpose, suitable fungicides or insecticides are chosen from the range of modern chemicals. Among the popular drugs can be noted “Nitrafen”, “Carbofos” and “Oxych”. And also for the spring spraying of grapes, a solution of urea, copper or iron vitriol will fit well.

One of the best anti-grabers is considered a borodic mixture, the solution is poured under the root.


In addition, in spring, mineral fertilizers contribute to the soil, allowing to maintain the active growth and development of green cover. Superphosphate and ammonium nitrate are well suited for this purpose. For arid sections in the spring, moisture profitable watering is often used.
