Already from the end of August and during September, the main task of caring for grapes is to help the vines to ripen.
It is important that before the onset of frost, the grape vine ripens and prepares for winter. Otherwise, the vine will not store nutrients and there is a high probability that it will freeze in winter, or will not produce a crop the following year.
Grape care in September:
- Harvesting grapes (early, mid-early, medium…). Timely harvesting has a good effect on the ripening of grape vines. If the vines are still grassy in September, and there is a lot of unripe crop, then it is necessary to remove 3-5 bunches for better ripening of the vines.
- Removal of all growth points. To stimulate the ripening of the vine, you need to cut out all the growth points. That is, all those shoots that grow and those shoots of the first order that were pinched above the first leaf in spring or summer must be cut. As a result, the following should remain on the vine: the vine and a leaf near the bud, as well as 2-3 first-order processes without a growth point in the upper part. All this is done only on those vines that are already beginning to ripen (the shoots have lignified, the bud is beginning to darken, and the vine is turning yellow). On green vines, the processes are removed only in the lower part of the vine, and the rest are pinched.
- Feeding. For quick ripening of grassy vines, it is necessary to use potassium. Treat the leaves (potassium monophosphate, sulfates or chelatin), cover the berry. If you notice signs of disease, cut out diseased leaves, process the rest.
- Watering is minimal, in the event of a severe drought. (1-2 buckets per bush).
- Caring for grafted shoots (puncture, excision of shoots). On strongly growing cuttings, remove the windings so that the vine does not stretch. Treatment with potassium. If necessary, cut part of the crop.
Аollow the above recommendations, you will have a rich harvest next year.
