How to prune grapes in spring

1. Pruning method

1. Keep buds: In spring, about 70-80% of the winter buds on the mother branches will germinate, and it is necessary to keep the buds at this time. Generally, the buds that are not growing well will be cut off. You cannot leave too many or too few buds. Too many will consume more nutrients, and too few will cause the flowers to fall off.

2. Remove buds: Usually there will be many buds on the mother branch, and the distance between each bud should be 15-20 cm. Each mother branch only needs to retain 2-5 new shoots, and the rest should be removed.

3. Pinching: Before the new shoots bloom, pinch off the top of the flower spike while leaving five leaves. For new shoots without flowers, pinch off the top while leaving eight leaves. In addition, the vines should be tied according to their growth.

2. Pruning time

Generally speaking, spring pruning should be done in March or April. Pruning at this time will not only help its growth, but also ensure better fruit setting. Just don't do it too early or too late.
