It is very unpleasant to see on grapes half showered ovary. The causes of the shedding of the ovary can be many. Consider the underlying causes and the measures that should be taken in any case.
• Adverse weather conditions. Formation of the ovary may stop due to excessive moisture, wind and cold suddenly occurring. In this case, help out hybrid varieties resistant to frost. Although they can respond to the bad weather, dumping the ovary.
• This may occur if the wrong bush clipped or tied up (in this case there is condensed with the plants and the inability pollination).
• This occurs if a given grape variety type of flower - exclusively female. the grape has functionally female type flower. In this case, next to it is necessary to put the sort of pollinator bisexual or homosexual to instill vine variety with bisexual flowers. Of a difficult situation, you can go out, placing the bushes with a female type of a bush with a male-female type of flowering.
• Determine what type of grape can be. If the bloom time of the flowers to consider carefully, we see that bisexual varieties stamens grow up. In same-sex varieties stamens are bent down. Each grape variety has its own characteristics that must be considered when buying the planting material.
• The ovaries may crumble due to lack of soil phosphorus and potassium, or an excess. Part of the plant is not enough boron. Therefore, spraying with a sheet of boric acid solution (buy may be in pharmacies) may solve the problem in the water. It should be borne in mind that boric acid is easily soluble in hot water.
• The solution is to fertilize potassium monophosphate bush (70 g in 10 liters water). Here the mixture is added to 15-20 g of magnesium sulfate (magnesium sulfate), 20 g of boric acid (borax), 7.5 g of manganese and 30-35 g of potassium sulfate. But we must remember that each of these substances should be diluted separately and then added to the working mixture. The resulting mixture was poured into a trench depth of 30 cm, which is dug around the bush, departing from it by 60 cm. If there is no potassium monophosphate, you can use the two-day extract of superphosphate. For this kilogram superphosphate pour 5 L of pure cold water. To prepare the working solution liter of extract diluted in 10 liters of water. Under five vines five or six buckets was poured mix. In the same solution, but reducing the dose can be sprayed and leaves. To make it take on 10 g of zinc sulphate, magnesium sulphate and boric acid, 3 g of manganese sulfate, 20 g or 25 g of potassium Potassium-magnesium and superphosphate liter extract.
On some varieties of grapes are beginning to fall already ripened fruit. This means that it is time to harvest. This feature and have grade Rusbol Ukrayinka. It is not necessary to discard the plant, they make good wine. These varieties are also good for the preservation of the juice or compote.
In order to avoid problems with the ovary is necessary to select varieties that feel good in this region and are adapted to the climatic conditions. It would be nice to buy grapes from growers know and see the variety in the area, ask about the features of growing and caring for shrubs data.
Grapes loves dressing ash, especially in sandy soils. The ash can be pre-diluted in water, but it is better to use in a dry form. A glass of ash spread over the surface of the soil around the bush, loosen the soil.
