Winter pruning of grapevines should be done one month after the natural leaves fall in autumn and 20 days before germination in the second year. It is not appropriate to prune the grapevines too early or too late. The main vines should be cut back, and dense branches, diseased branches, old branches, and weak branches above should also be pruned. As a result, the mother vine is pruned according to the number of high-quality buds. The remaining branches are left with strong branches and the weak branches are cut off.

1. Pruning time

Pruning does not start as soon as winter enters. It can be done one month after the natural leaves fall in autumn, and up to 20 days before germination in the second year. It is more appropriate to prune during this period. If the time is too early, the tree has not yet entered dormancy, and pruning at this time will cause damage to the tree. If the time is too late, the tree will soon germinate, which will have an impact on later growth.

Dense branches, diseased branches, old branches, and weak branches on the main vine must be pruned so that nutrients can be supplied to the main vine. This can ensure the main branch's later fruiting. However, when pruning, be careful not to make the incision too close to the main branch.

2. Fruiting mother vines: For the pruning of these branches, It needs to be decided according to the specific situation, growth and thickness. If there are more high-quality buds, 8-12 buds can be left and then pruned. If there are few high-quality buds, only 3-5 buds, 2-7 buds need to be retained. Prune after each bud.

3. The remaining branches: For the remaining branches, The main principle is to keep strong branches, prune weak branches, and remove branches that are not growing well.
