The flowering period of the grape is important for its growth and development. The quality of the crop, as well as its quantity, largely depends on the correct care of plants at this time of the year.
Description and duration of flowering
The flowering time of grapes varies depending on which region it grows in. As a rule, flowers appear in the second half of May. The flowering time depends on the grape variety. Flowering usually lasts about 10-12 days.
The vine begins to bloom from the base. It is completely covered with flowers only after a few days. The flowers of the grapes are small. They form neat inflorescences. During the first week of flowering, the grapes are pollinated. During this time, the flowers become moist and lighter in color.
Necessary care
During flowering, both young and mature grapes need special care.
Pinching shoots
At the beginning of summer, young shoots begin to grow actively. At this time, the gardener must do everything so that the plant gives all its strength to the formation of fruits, and not greenery. For this, the shoots must be pinched. If flowers are falling from the branches of the grapes, and the green shoots are growing too actively, you will need a hard clothespin. The gardener needs to remove part of the shoot, leaving no more than 5-6 large leaves above the inflorescence. If not too many young shoots appear, it will be enough for the gardener to remove the crown with 2-3 leaves.
Timely pinching will help slow plant growth by 10-14 days. It will bear fruit much better.
Pollination
You can increase the yield of a plant by paying attention to its additional pollination. There are several ways to do this.
- During flowering the gardener just needs to walk along the vineyard and shake the vine lightly. This is best done in the early morning.
- Special devices can be used to pollinate the plant . They are very simple to do. Rabbit fur is attached to small plywood shoulder blades. With the resulting tool, pollen is carefully collected from pollinating flowers. To do this, fur should be easily carried over the surface of the buds. With the same gentle movements, the pollen is transferred to the fertilized flowers. It is also recommended to process the grapes in this way in the early morning, after the dew has melted. In rainy or foggy weather, pollination of the bushes should be abandoned.
If there are very few flowers on the grapes, the situation can also be corrected. For this, drugs are used that can stimulate flowering. The most popular products that are suitable for this purpose are Ovary and Bud. The preparations are diluted in warm water and used for spraying plants . The use of such products not only helps to increase the number of flowers on the vine, but also helps to protect it from infectious diseases, as well as to strengthen it.
Inflorescence formation
If the plant bears fruit in large bunches, the gardener must take care in advance that there are not too many fruits in the fall .… To do this, he will have to manually remove excess inflorescences. In the process, you need to leave the strongest bunches. It is best that they are not too close to each other. If you do everything right, the vine will not suffer from unnecessary stress in the summer.
Fertilizer
To increase yields, grapes can also be additionally fed during the flowering period. It is worth starting to apply fertilizers to the soil only 6-7 days after the first buds appear . During the flowering of grapes, it is recommended to use high-quality nitrogen fertilizing. The introduction of such fertilizers helps to accelerate the formation of ovaries. One of the best feeding options is an infusion prepared on the basis of chicken manure. To do this, the product is mixed with water in a ratio of 2 to 3. The resulting solution must be placed in a plastic barrel and sent to a warm place for 10-12 days.
The product must be mixed regularly. Before use, the solution is diluted with water in a ratio of 1 to 10 . Some gardeners recommend adding wood ash to the container. Such a top dressing is introduced at the root. Suitable for fertilizing the vineyard and complex mineral compositions. These can be purchased at many gardening stores.
Fertilizers are recommended to be applied 4–5 days after the appearance of the first inflorescences.
Restrictions
In order not to harm future fruits and the plants themselves, at the time of flowering grapes, it is worth refusing to carry out some procedures
- Watering … Excessive soil moisture negatively affects the condition of the plant, as well as the quality of pollination.
- Treating the vineyard with chemicals … Spraying the area with them is only after the end of flowering.
- Digging the soil … In order not to harm the site, it is not recommended to dig up or loosen the soil next to the grapes.
All these procedures can be carried out later.
What if the grapes are not blooming?
Many gardeners are faced with the fact that the grapes planted on the site do not bloom. This can happen for several reasons.
- Excess water . Very often grapes do not bear fruit due to too much moisture in the soil. Over time, such a plant begins to weaken. To prevent this, the choice of a place for planting grapes must be treated responsibly. Also, don't water it too often.
- Cold winter . The most common reason for not blooming is damage to flower buds in winter. To prevent such a situation, grapes need to be well covered for the winter.
- Features of the variety … There are grape varieties that bloom later than others. Having planted such a plant on your site, you need to take into account all its features. If a 3-year or 4-year shoot does not bloom on the site, the owner of the site just needs to wait.
- Excess feed … Gardeners know that nitrogen fertilization contributes to the appearance of green foliage and flowers on vines. Therefore, in the spring, they introduce fertilizing with nitrogen into the soil. But an excess of such fertilizers leads to the fact that grape shoots become too fragile, and flowers on them do not appear at all. To prevent this from happening, you should not use nitrogen-containing fertilizers in August. In the second half of summer, it is recommended to feed the grapes with potassium and phosphorus.
- Disease … Grapes do not bloom even if it was affected by such a disease as gray rot, or mildew. The plant may well get sick in the spring. To protect the grapes, it must be treated with any suitable fungicide. This should be done no later than 6-7 days before the start of the appearance of flowers.
- Incorrect cropping . If the shoot has been pruned too much, it will not bloom. So that there are no problems with flowering grapes, in the process of its formation, varietal characteristics must be taken into account.
Sometimes it also happens that the plant blooms, but does not bear fruit. This usually happens due to the fact that grapes with female flowers are planted on the site. They are not able to pollinate on their own. To correct this problem, gardeners usually plant female flowering varieties next to bisexual varieties.
If you properly care for your vineyard, and also follow the advice of more experienced gardeners, there will be no problems with flowering and fruiting.
