Grape characteristics

The Bianca variety is used to make white table and fortified wines. Due to its raw material properties, it is also used for the production of cognac.

Bush description

The bushes are medium sized. Leaves have a smooth surface of dark green color. Shoots grow actively, each has 2-3 inflorescences.

Plants planted with the help of cuttings take root well and yield a crop already in the third year. The brushes have a cylindrical shape, weight - 100-150 g.

Fruit Description

The berries are small, round. The weight of each does not exceed 2 g. The color of the fruit is yellowish with a green tint.

The pulp is juicy, with a rich taste. The amount of sugar is 28%, so the berries are used to produce sweet and semi-sweet wine. Ripened fruits have an acidity of 7%, alcoholicity - 14%. The taste is felt floral or honey notes.

Grape growing

The Bianca variety grows well in any locality, it is only important to fertilize the soil. If it is clay, the vine is securely fixed.

If the soil has a high acidity, it is bred with lime. For wine species, light and heat are important, so it is best to plant them on the south side. The larger the slope, the better.


The optimal period for planting seedlings of Bianca grapes is the first half of October. It is important to consider the local climate. Seedlings are planted before the start of frost, the soil should not be too wet.

Description of the rules for planting seedlings:

  • The depth of the pit is 50-55 cm. This is important for protecting the roots in winter.
  • Cuttings are planted in thick rows. The distance between the seedlings should be 50-60 cm, between the rows - 2-3 m.
  • In the southern region, plants take root in late March. In the north - in late April or early May. The air temperature should not be lower than 12 ° C, and the earth - 8 ° C-10 ° C.

Plant care

The plant needs to be pruned regularly

To increase resistance to frost, the upper roots of plants are pruned. This is important because they are poorly protected and suffer from frost in winter. This affects the condition of the whole plant. Above the surface of the earth should be no more than 5 cm root.

Also, the vine is pruned. On one shoot leave 3 eyes. Due to this, the branches are not overloaded, the yield increases.


Bianca must be fertilized every year. Fertilizer is introduced in the spring before the shoots begin to bloom. Use 200 g of superphosphate and 100 g of ammonium sulfate per plant. Phosphorus is important for the formation of inflorescences and ripening of fruits. There are 2 methods of fertilizing.

Description of fertilizer application rules:

  • between the rows make ditches 40 cm deep, add fertilizer to them and fill it with soil;
  • at a distance of 40 cm from the seedlings, dig holes, throw fertilizer into them and sprinkle with earth.

At the end of June, fertilizer is introduced with nitrogen or nitrophos. In early August, fertilize with potassium in the form of foliar top dressing.

For top dressing take:

  • copper - 1.5 g;
  • sugar - 3 tbsp. l .;
  • boron - 1 g;
  • ash - 1 l.

The ingredients are mixed in 10 l of water and poured under the root of the plant. Potassium fertilizers are added in the same way. This contributes to the synthesis of sugar, which is important for wine grapes.


Grapes give a good harvest with medium soil moisture. In hot weather, it is important to water it often.

You can dig small holes near the bushes and pour water into them. On a large plot, it is more convenient to dig a trench and moisten the bushes through it. To keep moisture longer, the earth around the plants is loosened.

Diseases and Pests

Bianca resists many diseases, but sometimes suffers from alternariosis.

The variety also resists phylloxera. This is an insect that harms the foliage of grapes. Due to the high sugar content, wasps and birds love berries.

Disease control

A disease can ruin an entire crop

Alternariosis is a fungal disease that significantly reduces the amount of yield and can kill a plant if not treated.

Brown spots with a purple border appear on the leaves. Gradually they increase. It is better to deal with this disease by chemical methods. Effective processing of bushes Bordeaux mixture.

Description of the rules for preparing the mixture:

  • lime and copper sulfate are bred in different dishes;
  • lime is well mixed with water and filtered;
  • the solution of vitriol is filtered and little by little combined with lime.

Bushes are treated 5-6 times a season. Berries are eaten no earlier than 20 days after processing. Also use drugs "Trichodermin", "Quadrice", "Rapid Gold" and "Skor".

Pest control

To protect the bushes from wasps, dishes are placed between the rows with poison and sugar. This serves as a bait. Insect nests are also burned, but this is an ineffective method because it is difficult to find all the hives.

To protect the crop from birds, use firecrackers, ribbons and set scarecrows, but these are temporary and not effective methods of struggle. The best option is to use a mosquito net or any other network with small holes.


Alternariosis can actually be avoided if the organic remains of grapes are removed on time and proper agricultural practices are followed. Preventive spraying with Bordeaux mixture is useful.

It is important to apply mineral fertilizers on time: they increase immunity. Effective and the treatment of plants with fungicides.


The Bianca grape variety is considered a good technical species for growing. It has a pleasant sweet taste, gives a good harvest and is resistant to many diseases and temperature extremes.

This variety is used for the preparation of sweet and semi-sweet wines, as well as cognac. Sometimes it undergoes alternariosis, but the disease can actually be avoided, thanks to prevention.
