Flowering of grapes is one of the most important periods in the development of vines. At this time, the plant is susceptible to weather conditions and demanding care. The hot dry weather, which is necessary for the pollination of flowers in a natural way, contributes to a good harvest. If it is damp and cool outside, fertilization either does not occur at all, or the flowers and ovaries fall off.

The need to care for grapes during flowering is due to the fact that shrubs require nutrients and moisture. But you can not overfeed and fill the garden with water, and watering should stop 2 weeks before the proposed flowering. Otherwise, most of the inflorescences and ovaries will fall off, and clusters that have already formed will be subsequently affected by a fungal infection.

Let's consider whether it is possible to spray and fertilize the grapes before flowering and after, and what should be done on the plantation during this period.

Why grapes do not bloom: possible causes

For a start, let's look at the reasons why the vine does not bloom. The first of these is the female type of flowers, which needs a pollinator. An inexperienced gardener can experiment by transferring pollen from another bush by hand and observing whether a bunch is formed. If the experiment was a success, a male individual is planted next to it, for example, some kind of Kishmish.

Another answer to the question of why the grapes are not flowering is inappropriate weather conditions. The life cycle of a flower is about 10 days and at this time it is important that the air temperature is 25 - 30 ° C. If the thermometer shows less than 15 degrees, and the atmosphere is too moist, flowering slows down.

Also, the gardener should be aware that for pollination and the ovary of the grapes need a temperature above 17 ° C. Of course, it is impossible to influence the weather, and it is completely enough to artificially pollinate plants. How to do it:

  1. Shake trellis ropes in 1 half of the day,
  2. Collect and dry the pollen and pollinate the desired bushes puffs.

Pollinating flowering grapes do 2 - 3 times. The first manipulation is done when blooming the third or fourth part of all inflorescences, the next - during the mass flowering nursery. Doopylinia gives an increase of up to 30%.

To liana blossomed in full force, the grower can use drugs:

  • Immunocytophyte (1st processing of grapes before flowering, 2nd - after 10 - 12 days and 3rd - after 2 - 3 weeks after the second). The product can be diluted with Bordeaux liquid 1%,
  • Novosil (used immediately after blooming buds and repeatedly after 10 - 12 days).

After flowering, the care of the grapes can be supplemented with carbonation of the root-collectors.
