Mineral fertilizers for grapes

Many gardeners, for various reasons, do not plant grapes in their country house. Most are afraid that nothing will work out, that the grapes will not give a harvest, that they will not be able to eat delicious berries. But, as a rule, in order to achieve high yields, it is necessary to provide the grapes with appropriate care - add mineral fertilizers for the grapes

What mineral fertilizers do grapes need to fertilize?

The needs of grapes for mineral fertilizing depend on the growing season of the plant. Therefore, before proceeding with planting, carefully understand this issue.

• Phosphorus. At the beginning of flowering, grapes need exactly this nutrient, because it contributes to the active and rapid development of inflorescences, and in the subsequent setting of berries and ripening of bunches. The most commonly used superphosphate.
• Nitrogen. This micronutrient helps grapes to grow foliage in large quantities. From this it follows that most of all grapes need nitrogen-containing fertilizers at the beginning of the growing season, that is, in the spring. The most commonly used are urea and ammonium nitrate. In June and July, grapes almost do not need nitrogen, but at the end of summer it is not possible to apply it at all, because nitrogen activates the growth of leaves and shoots. And the plant does not have enough energy to produce fruits.
• Potassium... This trace element helps to speed up the ripening of fruits and prepare the plant for the arrival of frost. Therefore, it is necessary to feed the grapes with this mineral fertilizer closer to autumn.
• Zinc. This trace element helps to increase the yield of the plant.
• Boric acid. Accelerates the ripening of grapes, makes them tastier and sweeter. In addition, this microelement promotes pollen germination.
• Copper. This substance increases the resistance of grapes to frost and drought, therefore it is used in autumn, and this mineral fertilizer for grapes is used in summer.

Mineral fertilizers for grapes: how to feed?

Simple agrochemicals consisting of one substance, for example, ammonium nitrate, potassium chloride, superphosphate, and others, are excellent for feeding grapes. You can also use mineral dressings that contain two or three elements (ammophos or nitrophoska) and complex agrochemicals - Kemira, Florovit, Novofert and others.

But it should be understood that there will be too few agrochemicals for grapes alone. In order for the plant to fully assimilate the incoming nutrients, it must be added to organic matter (manure or compost).

Scheme of feeding grapes with mineral fertilizers

To feed the grapes with mineral fertilizers (both in spring and summer), it is necessary to dig grooves around all bushes with a depth of about 40 cm and within a radius of about 50 cm. Thanks to this method, the roots of the grapes get faster and more actively absorb nutrients.

• The first time they feed the grapes in the spring. For example, you can use the following recipe: 10 g of ammonium nitrate + 20 g of superphosphate + 5 g of potassium salt and dissolve all this in 10 liters of water. Pour 10 liters of solution onto one bush.
• The second time the grapes are fed with mineral fertilizers two weeks before the beginning of the flowering of the grapes. You can fertilize with the same solution that you used the first time.
• The third dressing is done just before the beginning of the ripening of the grapes.Potash fertilizers and superphosphate are applied to the soil. Please note that nitrogen should not be used.
• The fourth time you need to fertilize the grapes in the fall, when the harvest has already been harvested. Potash dressings are usually used, which increase the winter hardiness of grapes.

Schedule of foliar dressing with mineral fertilizers for grapes

Foliar dressing of grapes with mineral fertilizers should be included in the mandatory care of grapes, as well as root ones. They enhance the growth of grapes, increase their yield and increase winter hardiness.

• For the first time, such a top dressing is done before flowering, in order to prevent shedding of flowers, to increase the number of future grapes.
• The second time foliar dressing is applied after flowering, nitrogen cannot be used.
• The third time feeding is done when the berries begin to ripen, also without nitrogen.

Foliar dressings can be purchased at specialized stores.

It is necessary to spray the leaves on quiet days, when the weather is calm and calm. The best time for this treatment is early morning and evening, when the sun is not too active. In sunny weather, it is strictly forbidden to spray and water the plants, because the sun can burn the foliage of the grapes. Also, in order for the plant to better assimilate useful trace elements, 3 tablespoons can be added to the nutrient solution. Sahara.

Thus, fertilizing grapes with mineral fertilizers is very useful, and will help your plant to actively develop and bring rich harvests.
