When pruning grape branches, you should prune buds, top in time, prune branches, thin out flower buds, and prune after fruiting.

1. Prune young shoots. When the grapes begin to germinate, they need to be pruned. Prune the sprouting buds first, and remove all useless buds, especially late-growing, thin leaf buds. If two or three buds sprout from one bud, it is recommended to remove the secondary buds and keep only the main buds.

2. Topping in time. One week before the grapes bloom, the new shoots should be topping. First cut off the small leaf nodes at the top of the grape branches, and then remove the branches and leaves on the secondary shoots. This can keep the branches neat and can pollinate well, which can play a role. The effect of promoting flowering and fruiting.

3. Prune branches. Grapes have strong branching ability, so thin and weak branches should be cut off in time. Just keep the strong growing branches. For example, for annual grape vines, leave one branch 8 to 15 centimeters apart, and cut off the other branches. A vine of about one meter can have 9 to 12 branches.

4. Thin out the flower buds. During the flowering period of grapes, the flower buds must be thinned out in time. If there are too many flower buds, the branches may not be adequately supplied with nutrients and may suffer from poor growth. It is necessary to cut off all the overly dense and thin flower buds in a timely manner.

5. Prune after fruiting. Every year after the grapes bear fruit, the vines must be pruned again to remove the dry ones. All branches infected with diseases and insect pests must be cut off. It is best to keep only the strong branches of the current year. Proper pruning will help survive the winter and will also be beneficial to next year's germination.

When is the best time to prune grapes

Grapes can be pruned all year round, and the effects of pruning vary in different seasons. For example, pruning during the pounding season is the bud wiping method during the pounding season, which wipes out long buds, thin buds, and unruly buds, thereby saving nutrients. Summer pruning involves topping the fruiting branches and vegetative branches, sub-processing, pinching and ordering, followed by shaping the ears, thinning the ears and grains, etc.

The task of autumn pruning is to perform secondary pruning to remove closed branches, thin branches, and branches with a low degree of lignification, adjust the number of branches, make them exposed to light, improve lighting conditions, and make the frame The surface has strong permeability. The amount of pruning in winter is the largest and the most branches are removed. In addition, winter pruning is an effective method to determine the yield of the next year.
