The grapes are prized for their harmonious nightshade taste. If we talk about wine, then it turns out with a specific, tart-sour aftertaste. Something like red currant or gooseberry in aroma.

Yield

The described variety does not differ in yield. You can increase the yield and at the same time not be afraid of overloading the bushes. This will require an increase in the number of fruitful shoots.

The choice of planting material
Experienced gardeners recommend that beginners take cuttings and seedlings from those who made them from their vines and are professionally engaged in the production of such material.
You can evaluate the quality by cutting off a small amount of bark. When growing a bush from a cuttings and observing the rules of agricultural technology, survival rate is about 90%, the high quality of the plant is practically guaranteed. It is possible to control the development of grapes at all stages.
Subject to the rules of agricultural technology, survival rate is about 100%. The seedlings must be healthy. Pay attention to the absence of blisters, growths, or other signs of disease.

Growing features

Best of all, Sauvignon Blanc grows in the cool, where it acquires the necessary freshness of the aroma. If it grows in hot climates, then the fruits gain a lot of sugar, the wine turns out to be heavy. In the latter case, dessert drinks are made from berries.

The variety has special preferences for the type of soil. Heavy clay soil will not work; light to medium soils are best.The ideal solution is fertile humus-carbonate soil. The vine grows well on a slope, where groundwater is far from the surface.

Best rootstock:

  • Berlandieri x Riparia CO4;
  • Riparia x Rupestris 3309.

Landing

Depending on how you plan to place the one-year growth, a landing pattern is selected. If this is a high-stamped formation, assuming a free arrangement, then the 2.75-3 x 1.5 scheme is used.

The distance between the rows can be reduced if it is a vertical garter or low-stem bushes.

Landing features
In order for the vine to give a signal harvest after 3 years, it is necessary to take into account many factors - from the type of soil on the site to the nearby plants.

Pollination

There is no need for additional pollination, since the flowers on the grapes are bisexual.

Pruning

With standard pruning, 5-8 eyes are left on the bush. The best time for this is the end of autumn. As soon as the leaves fall, you can start working in two weeks.

Pruning is one of the main grape care procedures. Depending on the purpose of pruning and the type of plant, the appropriate type of formation is selected.

Watering

Water the grapes only if there is not enough rain. A 10-liter bucket is enough for a bush.

Irrigation schemes
In order for the berries to be large and juicy, it is necessary to organize full watering and feeding. All standards must be adjusted for weather conditions and the rate of evaporation of the liquid.
With a frequent watering scheme, it is recommended to moisturize once every two weeks (that is, twice a month during flowering and the appearance of berries) so that the earth is saturated 50 cm deep so that the plant does not switch to superficial (dew) roots. This amount can be reduced by mulching the crop with straw.
With a rare irrigation scheme, choosing the age and ripening period of the grapes, you can use the standards presented in the table in another article.

Frost resistance and the need for shelter

When cultivating the described variety, it should be borne in mind that it does not differ in frost resistance. In temperate continental climates, shelter is required for the winter. The vine is not damaged at -22 ° C. If the buds die from frost, replacement buds grow in their place, but it is impossible to get a crop from them, since they are in most cases sterile.

As a shelter, multi-arm fans or oblique cordon are used. The vine is laid so that, when removed from the trellis, it is not damaged and buried in the ground.

Organic material is also perfect as insulation:

  • straw;
  • reed;
  • shavings.

A layer of roofing material must be laid on top, you can use a film. The main thing is that the vine inside is dry and remains so until the shelter is removed.

Shelter for the winter is a very important step for the preservation of many grape varieties after wintering.

Diseases and pests

Especially often grapes are affected:

  • gray rot;
  • mildew;
  • oidium.

Gray rot most often affects young plants. As a remedy for it, use "Fundazol", formalin.

Of the pests, the leaf roll is considered the most dangerous. Untimely processing will lead to the fact that the bushes will die, as the insect will eat the foliage. The fight is carried out by means of "Metaphos".

Wasps love grapes, this is one of the reasons why it is not worth thinning. Special traps are set for pests in the vineyard, sugar syrup is placed or the bunches are wrapped in a net.
