You must control the time when pruning. It is recommended to do it from 20 days after the leaves fall to 15 days before budding in the second year. Not too early or too late, otherwise it will affect its growth. Too early will reduce cold resistance, which is not good for winter. Too late can easily lead to injury and bleeding, which will be detrimental to later germination. In addition, pay attention to the pruning method. The cut should not be too close to the bud eye, as it is easy to lose water.

1. Pruning time

For southern grapes, it is recommended to prune from 20 days after leaf fall to 15 days before budding in the second year. The time of pruning must be controlled well, not too early or too late. Too early will reduce its cold resistance, which is not good for winter. Too late will easily lead to bleeding, which will weaken the tree vigor and be detrimental to germination. In addition, pay attention to the pruning method.

1 2. Short-shoot pruning: After pruning the branches of the current year, two or three buds should be left. Do not leave too many buds, and you must not leave them at all. Of course, it also depends on the variety. This method is suitable for European and American hybrid varieties, which can grow better in the later stages of treatment.

2. Mid-shoot pruning: Keep four to seven buds after pruning. This pruning method is suitable for varieties with high fruiting rate and medium growth potential, such as Victoria, Ruby, Red Globe and other varieties. This method is very suitable for use.

3. Long-shoot pruning: When pruning, leave eight branches of the current year to eleven buds. This method is suitable for varieties with high flower bud establishment, low fruiting rate and vigorous growth. Such as Crane or Beauty Finger, etc.

3. Precautions

When pruning, be careful not to make the cut too close to the bud eye, otherwise the cut will easily lose water and the bud eye will easily dry up and die. It is recommended that the cut be made in the upper middle of the two buds, or 2-4 cm from the eye of the bud.
