Choosing the best frost-resistant grape varieties

Choosing the best frost-resistant grape varieties

Traditionally grapes grow in warm and sunny southern regions. These include Georgia, Italy, France or Kuban. Due to their taste, these berries are very popular. In addition, grapes are the main material for making wine. Therefore, more and more often, its juicy fruits are being grown in more northern regions. Gardeners in central Russia select varieties that can withstand a frosty winter.

Peculiarities

The climate in most of our country is not suitable for heat-loving berries. Its branches do not withstand winter frosts and a long absence of heat. To solve this problem, frost-resistant grape varieties are cultivated. The first experiments in this area were carried out by I.V. Michurin. Today, there are already several dozen such varieties. They can survive the conditions of quite severe winters. Winter-hardy breeds can withstand temperatures below 29 degrees. Such breeds differ in the way of wintering - there are covering and non-covering varieties.

Covering grapes tolerate winter temperatures down to -27 degrees. To avoid damage by severe frosts, with the onset of a cold period, it is covered.

Uncovered grapes are even better adapted to harsh winters, they can withstand frost in -30 degrees. The most frost-resistant species may not even freeze at temperatures around minus 40-45 degrees. Such varieties are suitable for planting even in Siberian conditions.At the same time, the vine of this culture can be left for the winter without additional shelter. Uncovered grape varieties are intended for making juice and distillation of wine due to their rich taste.

Varieties that are resistant to cold usually bear fruit profusely. This is the main subtlety of growing such varieties of grapes and the danger to an inexperienced gardener. During the period when the bunch is gaining its maturity, all the nutrients are taken by the berries. In the event that there are too many brushes, the roots and vine may be left without recharge. The readiness of the plant for frosty wintering is reduced. The quality of the berries becomes worse, and the grape plant itself weakens and dies in winter.

Therefore, it is very important to monitor the number of ripening brushes in frost-resistant varieties. Even the most cold-resistant variety can be left without shelter for the winter no earlier than the third year from planting.

How to choose?

There are many varieties of grapes, among them there are universal, technical, table varieties. Some are better suited for processing, others can be eaten with pleasure. An important indicator of the quality of the variety is the high content of juice in the berries. If the sugar content is not less than 20%, the fruit is saturated with vitamins and minerals.

To grow grapes in cold winters, the crop must withstand frost, preferably without shelter. Also, good varieties of this berry are quite resistant to pest attacks and diseases. The disadvantage of this variety is the difficulty in care. No matter how winter-hardy the variety may be, part of the shoots and the upper part of the root system freeze and die in winter. Therefore, in the spring the grapes need to be cut and fed in a timely manner.

The berries of such varieties are small, the shape of the bunch does not grow in an ideal cone.Usually they belong to technical species, so the crop is processed, such fruits are not consumed raw. There are also table varieties among them, but they still lose in taste to their southern counterparts.

For central Russia (for example, for the Tver region), it is better to choose winter-hardy plants with early ripening of about 85-125 days. These include the following cultures:

  • "Aleshenkin";
  • "Victoria";
  • "Beauty of the North";
  • "Crimean pearl";
  • "Moscow stable";
  • "Lydia";
  • "Isabel";
  • "Bianca".

For the Leningrad region, it will be more difficult to pick up grapes, because the conditions there are more severe. Suitable varieties that will produce a crop no later than mid-August and will be able to survive a cool, low-sunshine summer. Varieties suitable for this region:

  1. "Amursky";
  2. "Muscat";
  3. "Zilga";
  4. "Isabel".

In some southern territories, for example, in Kyrgyzstan, along with elite grape varieties "Kishmish" and "Saperavi", frost-resistant species are also grown, as in some mountainous areas the temperature can drop to -30 degrees.

  1. Among all these varieties, uncovered "Isabella" and its hybrids can survive the winter. They can winter at temperatures down to -40 degrees. The berries are quite sweet, blue, with a black coating. Reviews about its productivity are very good.
  2. Grapes "Crimean Pearl" - covering, tolerates cold to -24 degrees. The berries are white, large, with a rich aroma of nutmeg.
  3. Variety "Marinovsky" is often grown in home gardens. It is quite undemanding, high-yielding. It does not need to be covered for the winter. The description of the variety allows us to say that the grapes are universal. It can be consumed raw and made into wine products.
  4. Grapes "Svetlana" - large: the weight of the bunch can reach 1 kg. The berries are green, cold resistance up to -25 degrees.

Among varieties with high resistance to low temperatures, there are weaving species that can be used to braid a gazebo, hedge or garden arch.

Uncovered weaving grape varieties are good for landscaping the site and creating shading.

Growing advice

Covering grape varieties for the winter are removed from the supports and placed under a layer of straw, burlap and polyethylene. Non-covering varieties are easier to care for - they do not need to be cut in a special way, forming a vine for winter. For such grapes, preventive treatment from pests is sufficient; they have good resistance to diseases. Often, to improve the quality of the crop and additional plant protection, the vineyard is processed according to the following folk recipes:

  • milk solution in a ratio of 1: 10;
  • mullein infusion 10%.

Crops that do not need to be covered for the winter can be left on supports after shedding their leaves. Plants after reaching the age of three can be left on the street, caring for a regular tree or shrub. Before wintering, you need to provide grapes with top dressing and watering. To do this, 4 buckets of warm water are poured under each vine bush with the addition of 500 grams of ash.

The most dangerous thing for frost-resistant grapes is a snowless winter. The root system may be subject to freezing, and in the spring the bush will have to be saved. To avoid unpleasant consequences, the soil in the hole with the vine is loosened for a sufficient amount of oxygen to enter the soil. The vine must be removed from the support, rolled into rings and laid on the ground. After that, a simulated greenhouse is arranged on top - covered with a film and its edges are fixed.The vine must take new roots. With the advent of spring, the grapes are watered before flowering, watering is stopped after the berries begin to ripen.

Pruning grapes will help avoid overloading the plant. Dead lashes are removed in the spring. Extra brushes and shoots are disposed of during the growing season.

It is important to plant grapes correctly. The place should be illuminated by the sun from early morning until evening. As a rule, these are the southern slopes. It is better to protect the grapes with a hedge from the wind. The bed is recommended to be made raised, bulk.

Tapestries under the vine are dug into the ground. Seedlings should have a strong root system and live buds. Planting grapes is best in May. Sometimes planting is done in October before winter. In this case, the seedlings are placed under the jars and covered.

Diseases and pests

Frost-resistant grapes resist diseases quite well, however, they occasionally infect plants.

  • Powdery mildew leads to poor growth of grapes - the leaves become curly and covered with a gray bloom, the berries deteriorate. The disease is treated with drugs "Thanos", "Thiovit Jet", "Topaz".
  • Downy mildew (mildew) leaves oily yellow spots on the leaves. A gray coating appears on the reverse side of the sheet, the affected parts rot. The infected areas of the bush are removed, the rest is treated with fungicides ("Thanos", "Mikal", "Antrakol").
  • black spot manifests itself in the form of red marks on the fruit, vine or leaves. Subsequently, the spots become discolored. With a wide defeat, it is impossible to save the vineyard, so it is necessary to carry out preventive spraying of the plant with antifungal fungicides (Thanos, Teovit Jet, Topaz).

The vines are also attacked by insects. The owners of the vineyard periodically have to protect the fruits from pest attacks.

  • Wasps. The sweet fruit attracts winged insects that pierce the skin of the berry, extracting the juice. A damaged bunch spoils quickly. Therefore, to save the grapes from wasps, you can destroy wasp nests early in the spring or set up traps with insecticides. It is also recommended to smoke wasps or cover the vine with a breathable insect net.
  • Mite. On grapes there are spider, leaf and felt varieties of the insect. From tick attacks, plants are treated with fungicides.

Grapes are also attacked by rodents - mice. They gnaw the buds of the vine during wintering. Covering varieties are especially susceptible to this. Ultrasonic devices are used to repel rodents.
