Description of Chardonnay grape variety

This plant belongs to the group of West European grape hybrids that are distinguished by their thermophilicity, as well as the need for a certain microclimate. This feature strongly affected the morphological properties of the variety, which was reflected not only in the appearance of leaves and shoots, but also on the characteristics of the crop.

Bush description

In front of the gardener "Chardonnay" opens as a medium or tall, branched bush. Its brown shoots are devoid of knots. The leaves on the vine are light green, but with age, their shade can change to grayish green.

After flowering, in the place of bush inflorescences, neat clusters of regular conical shape, small sizes are formed. The average length of the bunch is about 11 cm, the width is not more than 10 cm (at the base).

Due to the peculiarities of the development of flowers, the Chardonnay inflorescences are often showered, this helps to reduce the number of berries in a bunch by one third. Due to this, it is quite loose, but resistant to mechanical stress. The average mass of a bunch is 900–1000 g.

Technical grape varieties also include:

Description of berries

Growing Features

Chardonnay grapes have been successfully cultivated for many centuries in regions with a mild climate, therefore, the cultivation of this plant will require appropriate conditions. The most attention should be paid to the planting procedure: in order for the plant to feel good, you need to choose not only the right place, but also the best time for this.

Landing period

This grape is planted in autumn, in early October, or in spring, in the first half of March. Spring planting is the best for growing crops. This is explained by the fact that during this period there is a natural activation of plant organisms after hibernation.

It consists in accelerated doubling of cells and metabolism, which causes instant rooting of the cuttings, as well as their adaptation to the environment. Winter planting is used only in the southern latitudes, otherwise in winter weakly rooted grapes will freeze.

Important! To avoid freezing of young seedlings in a temperate or colder climate, they are planted to a depth of at least 60–80 cm.

Ripening period

This plant belongs to the species of medium ripening period, from the beginning of the growing season to fruiting no more than 140 days pass. In this case, a prerequisite for an early technical ripeness of berries is the total temperature for a period of at least 2700 ° C.

Otherwise, the ripening of the fruit is delayed or does not occur. Under warm spring conditions in a temperate climate with features of subtropical temperature conditions, ripening of grapes is observed in September.

Grape care

This grape is one of the few plants that, when cultivated, does not require specialized care. In order for the variety to produce high-quality fruits and rich harvests, plants require a standard set of agricultural practices and measures. At the same time, care should be taken carefully, since even a short neglect of this can drastically reduce the final yield of ripe fruits. We recommend reading how to transplant grapes correctly.

How to water Chardonnay grapes

This variety does not like excess moisture, but watering is important for it, since a lack of moisture can inhibit the growth and fruiting of the vine. Young plants are watered every week, adults - no more than 1 time in 2 weeks.

For irrigation use clean well-maintained water, heated to ambient temperature. Cold water is undesirable for watering grapes, as it can cause depression of immunity and a cold of the bush. At the end of autumn, watering is stopped, from this moment the vineyard is prepared for a long wintering.

Grapes are watered under the root, however, the plant responds best to abundant irrigation of not only soil, but also shoots, as well as foliage. Depending on the age of the bush, 5 to 20 liters of water are used for the procedure.

We advise you to find out why grapes decay, as well as why grape berries wilt on the bush.


Pruning of grapes is carried out to form a crown or for sanitary purposes. Sanitary pruning is carried out in early autumn or spring, during the procedure on the bush old and non-viable shoots are removed, as well as excess branches that reduce the yield of the plant.

Also, thinning of shoots is carried out during the summer, which helps to accelerate the ripening of the crop and its quality. During the growing season, it is necessary to monitor the load of the bush, the clusters on the fruiting shoots should be evenly distributed, without burdening the bush.

The plants are molded in autumn and spring, combining the procedure with sanitary pruning. The shape of the future bush is determined, first of all, by the temperature regime of the growing area. In warm regions with a mild climate, small bushes 60 cm long are created from vines. In the temperate zone, they prefer to grow crops on adult lignified shoots, which helps to shorten the ripening period. Read what should be the correct pruning of grapes in the spring.

When trimming Chardonnay, you must always adhere to the following recommendations:

  • the optimal length of the bush should be in the range of 65-120 cm;
  • green shoots of plants should always hang down freely;
  • each bush should contain no more than 4 fruitful links;
  • no more than 12 viable buds should be left on grapes;
  • the clusters should not shade, so all excess foliage must be removed.


Mulching of the culture is carried out in order to protect the vineyard from drying out, and also to create a special microclimate in the soil that favorably affects the development of shoots of the bush and berries. In addition, mulching helps protect the root system from freezing, which is quite important for all vineyards from temperate and northern latitudes.

The procedure is carried out immediately after the snow melts, or 7-10 days after planting the cuttings. For this, the root layer of the bush is covered with a special covering material, the so-called mulch. Its role can be played by a 10-15 cm layer of chopped straw, hay, sawdust, coconut bark and so on. They can be replaced with special agrofibre made of polymer materials.

Important! "Chardonnay" successfully bears fruit only in mild and moderately humid climates, excessive moisture causes cracking of the fruit and putrefactive damage to the root system.

Disease prevention

Chardonnay bushes are considered resistant to various ailments of grape plants, so they are rarely affected by such pathologies. However, in temperate latitudes, the plant often suffers from excessive moisture, which creates a favorable environment for the development of the main enemies of the culture - fungal infections.

It affects the fruits and the most juicy parts of the plant.Every 10 days, from the beginning of the growing season, until the appearance of full-fledged berries, the bushes are sprayed with Antracol, Bordeaux liquid, Kuproksat, Ridomil or copper chloride.
OidiumLight smoky coating that affects fruits and berries.In spring, grapes and the root zone of the soil are treated with the Azofos fungicide, throughout the growing season the vineyard is sprayed once a month with a solution of colloidal sulfur.
Gray rotGray plaque on leaves and fruits.Once a month throughout the entire growing season, the bush is sprayed with a solution of Anthracol, Acrobat, Kuprosat, Ridomil or Thanos.
