Grapes are a heat-loving culture, the quality characteristics of which are significantly reduced under the influence of negative environmental conditions. The shelter temperature of the grapes when preparing the plant for wintering should remain within 5 ° C.

Temperature regime for sheltering grapes

Time frame

To protect the vine and the root system, the shelter procedure is carried out in October. It is important not to wait for the first frost, the delicate vine, under the influence of cold, loses its flexibility and soon breaks down, thereby causing the death of the plant.

The shelter temperature of grapes for the winter directly depends on the characteristics of the variety. In the presence of non-frost-resistant varieties, it is advisable to start the procedure at the end of September.

Frost-resistant grapes are covered at temperatures below 0 ° C, before the first snow falls. This is explained by the fact that a layer of snow that has fallen on the protective coating will maintain the temperature inside the greenhouse, which is necessary to prevent the roots from freezing.

Preparatory procedures

To cover the tree in the fall, remove all fruits if they remain after assembly work. Then proceed to pruning the grapes. When forming the crown for wintering, get rid of immature, dry shoots and weeds. Next, remove it from the trellis by twisting a long vine and tying it with twine. To reduce the risk of rot, treat the plant with a copper sulfate solution.

A few days before the culture is sheltered for the winter, water the plantings abundantly - the moist earth will withstand the cold due to water vapor, which will warm the root system for some time.

Earthen shelter

This method is the most common among summer residents.

• dig grooves along the shoots 20 cm deep: making deep ditches is not necessary, earthen embankments will be enough;
• carefully place the branches in the ditch and cover them with earth;
• the height of the soil should not exceed 40 cm: if the height is below the optimal indicator, the eyes will freeze over the winter.

Slate covering

Burlap is useful for wrapping the vine

With the intention of preventing the erosion of the soil embankment, gardeners use slate, an inexpensive material used to insulate plantings.

Cover the collected vines in bunches with dry foliage, hay or wrap in burlap. On top of the protective layer, install the slate slabs with a house. To prevent slate slabs from falling, secure them with stones or bricks, if desired, fix the material with earthen embankments.

Shelter of grapes with wooden shields

Using wooden shields in gardening is somewhat more difficult than the methods described above. You yourself have to put together shields from wooden boards or boxes.

The outer side is closed with roofing material (hammer or simply cover from above, after installing the structure). By giving preference to structures of this type, you will provide your garden with a reliable shelter for many years.

Before installing the shields, perform the initial preparation of the plant by wrapping its branches with burlap or strewn with earth.

Do not forget to protect the ends of the structure from strong winds. Plywood or the remnants of roofing material is perfect for this.

Covering grapes with foil

The construction with foil is identical in its properties to greenhouses. Place wire arches along the neatly folded shoots and stretch the film over them. It can be secured with stones or special weights. Apply a generous amount of organic fertilizer to the top of the branches before covering the plant with plastic wrap.

It is important to leave gaps, otherwise the plant will mate and begin to rot, which is equal to the death of the grape tree.

Winter protection

A vine spread out on the ground attracts rodents and pests, therefore protection from external destructive factors is an important component of wintering. The grapes withstand the whole winter if the necessary rules for plant protection are observed.

1. Set up mechanical traps around the perimeter of your garden to trap rodents. Plastic bottles with a volume of 5 liters can act as a trap, in which you need to put a little cotton wool soaked in sunflower oil.
2. Spray or apply chemicals: Difenacin, Brodifacum, Flocumafen.
3. Scarers are one of the most humane ways to control pests. Place containers with a substance around the perimeter of the garden, the pungent smell of which will scare away rodents: naphthalene, kerosene, Vishnevsky's ointment.

Major mistakes

Improper shelter leads to the death of a young plant. Common mistakes in gardening and how to solve them:

1. In the process of creating a shelter, they dig out the earth cover from under the root system of the grape tree - this is the reason for the freezing of the roots and the absence of fruits in subsequent seasons. The soil necessary for the whip can be taken only on a free site, but it is better to buy it separately.
2. Weak fixation of the covering material. Sharp gusts of cold wind will leave the vine defenseless and impair its health. To securely fasten the structure, mark out the iron sides, which will act as an obstacle to the wind and heavy snowfall.
3. Failure to comply with the temperature regime. Forgetful gardeners are faced with freezing of roots and vines, so remember that grapes need to be covered for the winter at temperatures not lower than 0 ° C and before the onset of night frosts.
4. Lack of treatment leads to active reproduction of bacteria and insects under the covering film.

Conclusion

Now you know at what temperature to cover the grapes for the winter. The creation of a shelter is a painstaking process, on the correctness of which the health and fruiting in summer depend. Correctly following all these recommendations, the plant can withstand the most severe frosts.
