In spring, gardeners have a lot to do, but in the midst of all these chores, they must definitely pay attention to grapes.
During this period, the liana-like plant needs feeding, which will subsequently provide a solid harvest.
But grapes need to be looked after not only in spring. The plant also needs attention in summer and autumn.
Secrets of a Rich Harvest
1. In spring, grapes are fertilized with humus and urea. Top dressing is done during the bud swelling phase. But experts advise not to add a lot of nitrogen fertilizers, otherwise the bushes will grow too much later.
2. Winegrowers have a little trick that also affects the yield. In the spring, plants are treated with iron sulfate to slow down the activation of juices and slightly delay the swelling of the buds.
Thanks to this procedure, the vine will rest, gain strength and receive protection from major diseases.
3. In autumn, grapes are fertilized with double superphosphate and wood ash. Top dressing at the end of the season creates a foundation for the harvest in the following season. Many winegrowers add potassium sulfate and potassium chloride in the fall - 40 g and 10 g per 10 liters of water.
