How and when do grapes bloom?

The flowering of grapes is a time on which depends directly on how and in what quantity the grapes will bear fruit.Therefore, it is necessary to create appropriate conditions in order to finally collect high-quality crops in large quantities.

In most cases, the grapes begin to bloom in late spring at a temperature of 25-30 degrees. However, certain varieties bloom at a lower temperature, it depends on the region. European grape varieties, accustomed to a mild climate, simply do not fertilize at low temperatures.

An important feature is that the weather must be dry. Also, you can not water the grapes during flowering and a few days before it. The rain at this time is very harmful for the plant, because it washes away the pollen from the inflorescences and there may be no harvest. In case of rain, artificial pollination should be carried out (if the vineyard is small in size).

The flowering process lasts only a few hours in the morning, because at this time the most suitable conditions for this. The rest of the time the buds are closed. Although some flowers may bloom late. The entire period of fertilization lasts from one to two weeks.

The number of ovaries is strongly influenced by weather and soil. If the soil is poor in nutrients and mineral components, then the clusters will be small and in small quantities.

In order for the vine to survive the period of flowering and pollination, It is necessary to follow certain guidelines for preparation.

• In early spring you need to form bushes. For this you need to tie the shoots on the frame, cut off unnecessary. Correct the branches so that future clusters have access to the sun, but do not overdo it.
• Before flowering, water the grapes regularly, plentifully, finish all the water procedures in about a week.
• Fertilize the plant, too, should be a few days before pollination. The trace element that positively affects grapes is boron. Consequently, it is possible to use drugs and fertilizers, which contain this component.

• Spraying the grapes against diseases and pests can be 4-5 days before pollination. The finished composition must be diluted in water according to the instructions and fully irrigate the bush.
• In heavily growing bushes, it is necessary to cut off excess buds in order to remove the excess load from the shoots and to provide more nutrients to the remaining clusters. Also, trim the inflorescences need on the bushes, which bear fruit for the first time.

Continuing to care for grapes after pollination and flowering is necessary in order to harvest a good harvest in the future. Therefore, you need to perform certain actions that will contribute to this.

• You can spend artificial pollination in case of bad weather or other factors. To do this, you need to shake the frame, to which the grapes are tied, so that the pollen crumble onto other flowers. Such actions should be performed a couple of times for the entire period of flowering in the morning, when the dew comes down.
• Approximately a week after the start of flowering, you can fertilize the grapes. To do this, use organic matter (a mixture of chicken droppings and water), and you can buy fertilizer with potassium and nitrogen, which also includes boron. Boric acid has a positive effect on the development of the vine.
• To improve pollination, you can spray the leaves with an aqueous solution of honey to attract bees.

• Fragments of young grape shoots are also made in order to unload the bush and send more nutrients to the clusters. You can break off branches that are not too thick and about 15 cm long. Using this method, you can not be mistaken, because the fragment is made with your hands, and if the shoot is already strong, it will not break off with ease.
• For the same reason, hold and prune grape shoots. To do this, you need to remove the top of the bush, about the size of which is about 10 sheets above the topmost cluster. Thus, the nourishment of the bush will be redirected from the top, and the berries are protected from active sunlight.

There are also actions to avoid:

• water the grapes during pollination and flowering;
• loosen and dig up the ground around the bush;
• use chemical fertilizers;
• use wood shavings and sawdust in fertilizer grapes.

Every grower at least once wondered for what reason does not bloom 3-year-old grapes or bushes of a different age. The reasons for non-flowering can be very different aspects.

• Excessive fertilizer bush organic matter. From the overabundance of such an element as nitrogen in grapes, active growth of leaves and shoots is observed. They pull on a stream of nutrients, and because of this, the bush does not bear fruit. In addition, resistance to low temperatures and diseases is reduced.
• Wrong wintering. It happens that the plant freezes and the branches are already incapable. In this case, spring pruning will help. It is necessary to remove the shoots that have suffered, and in their place will grow new and healthy.
• Inappropriate place. Grapes like heat, so the planting site may not be suitable for it, and the plant will not pollinate.
• Diseases and pests. Grapes can not bear fruit due to disease. Then you need to inspect the plant and identify the nature of the disease. In the fight against insects, you can purchase special drugs and use them according to the instructions.
• Incorrect trimming. If in early spring to cut the bush too hard, then there simply will not be a place for the formation of inflorescences.

Terms of flowering grapes are approximately the same in all varieties. Grapes bloom in late spring - early summer. Interestingly, the flowers open early in the morning, and in the afternoon - only those that are late. The flowering period itself lasts from one to two weeks.

In the Rostov region is widely grown various varieties of grapes, because there is a mild climate for this plant. Clusters grow quite large. Their weight reaches from 500 grams to one and a half kilograms (!). Berries ripen in 4-5 months and have a pleasant taste. Grapes in this area are highly frost resistant (up to -25 degrees).

Krasnodar Territory is similar to the Rostov region climate, since they border on each other. Bunches of grapes ripen within 3-3.5 months, their weight - from 400 to 700 grams. Varieties in this region are also frost resistant.

Vineyards in the Crimea have their own history and popularity. The special climate of the peninsula allows you to grow a variety of grapes. Wine varieties are also grown here, and just for food, which ripen predominantly at the end of summer for 3-4 months. Berries have different tastes: from sweet to slightly sour.

In order to get a big harvest of tasty grapes try to follow some tips.

• To liquid fertilizers are better absorbed by the plant, it is recommended to use the dug pipes.
• Since the grapes are a heat-loving plant, for its planting it is necessary to choose areas on the southern and south-western sides.
• Planted grapes need at a distance of one meter. Between the rows there should be a distance of 3 meters.
• Every few years you need to fertilize the land near the grapes with potassium salt.
• To prevent frosting of the roots of the plant, it should be planted in the ground to a depth of about half a meter.
• Do not plant grapes in the shade.
