3. Precautions for pruning

Pruning of southern grapes should be done between 20 days after leaf fall and 15 days before bud break, usually between December and January. Be careful not to prune too early or too late. Too early will reduce cold resistance, and too late will easily lead to bleeding, which is detrimental to later germination and growth. In addition, the pruning method should be determined according to the specific growth and variety of the tree, and the cutting edge should not be too close to the bud eye to avoid water loss.

1. Pruning time

It is recommended to prune southern grapes between 20 days after leaf fall and 15 days before budding, usually between December and January, and not too early , and not too late. If you prune it too early, it will reduce its cold resistance. If you prune it too late, it will have already begun to germinate, which will easily lead to bleeding, weaken the tree's vigor, and be detrimental to its later growth.

2. Pruning method

1 2. Short-shoot pruning: When pruning, you should pay attention to the specific growth and variety of the tree. If it is a European and American hybrid, it is recommended to use short-shoot pruning. It is enough to leave only 2-3 buds on the current year's branches, which can save a lot of nutrients and facilitate flowering and fruiting in the later period.

2. Mid-shoot pruning: This method is suitable for trees with high fruiting rate, medium growth and low flower bud placement, such as red globe and ruby. After pruning, 4-7 bud eyes will be left on the current year's branches. That’s it.

3. Long-shoot pruning: This method is suitable for vigorous growth. , tree species with low fruiting branch rate and high flower bud growth areas, such as Creson, Beauty Finger and other varieties. After pruning, it is enough to leave 8-11 buds on the current year's branches.

3. Precautions for pruning

Pay attention to the specific pruning position. The cut should not be too close to the bud eyes, otherwise it will easily lead to water loss and the bud eyes will not germinate better. In addition, attention should be paid to the length of the branches. Those with strong growth should be longer, while those with weak growth should naturally be shorter.
