The pruning of pepper mainly needs two aspects, one is shaping, and the other is pruning. The two need cooperation. The principle of pruning is generally that the main branches of pepper should be less and the branchlets should be more, because the fruiting branches of pepper are mostly on the branchlets.

In addition, from the description of the problem, we can basically know that it is a pepper tree in the early fruit stage. The pruning principle of this pepper tree is "thinning", because the pepper tree is still in a period of continuous upward growth although it has borne fruit at this time, so it needs to be thinned to avoid excessive pruning affecting the later growth of the pepper tree and the yield of the pepper tree in the full fruit period.

At this time, Zanthoxylum bungeanum generally does not cut branches, but carries out more shaping steps such as supporting branches, pulling branches and bending branches. Let the trunk of pepper continue to grow and cut off some extra branches. Generally, about 4 branches at the base can be kept, and the rest can be cut off.

Branches that grow too densely can be thinned to adjust the degree to which Zanthoxylum bungeanum trees receive light. Some overlapping or parallel branches of Zanthoxylum bungeanum can be cut off and kept. Generally, cutting off the upright branches and keeping the flat branches can promote the growth space of pepper. If you encounter a strong upright branch, you can cut it short or pull it out or do other work.
