1、 Proper cutting

The proper cut is to leave enough space for the growth of buds, but not too far away, and the section should not be too inclined

2、 Trim in time

Three branches can be trimmed at one flowering stage. A vigorous pruning shall be carried out from March to April in spring to ensure the consistent length of branches, leaving thicker branches truncated; After about 20 days, when the first branch grows tall, the second pruning will be carried out from late June to about July; The third pruning is in August, no later than the middle of August

3、 Pruning method

1. Short cut: cut off one section of a year's branch. If half or 1 / 3 of the branch is cut off, it is a heavy short cut. This practice can stimulate the lower bud and promote the faster growth of new branches

2. Cut the lower part of the branch for more than one year, which is conducive to the growth of the shoots

3. Pruning: cutting off the branches that have been growing for many years can make the old tree strong again

4、 Precautions

Vertical downward branches and Cross branches can be removed; Parallel branches can remove weak branches; After flowering, the over dense branches, overgrown branches and weak branches shall be thinned
