There are many ways to prune Zanthoxylum bungeanum, and in the early stage of its fruiting, thinning branches is the main method. At this time, although the pepper tree has borne fruit, it is still growing, so it is necessary to cut off its branches from the base in time, and some branches and buds that are too dense, cross and overlap should also be cut off appropriately, so that the plant can better receive light and promote better results.

2. Shortcuts

Short cutting is a common pruning method, which mainly repairs the main branches that are too vigorous and aging during the growth of Zanthoxylum bungeanum, so as to reduce nutrient consumption and promote the growth of new branches. Basically, the main branches should be shortened by 2/3, and 2~3 main branches should be kept for them to continue to grow.

3, plastic pruning

After the seedlings of Zanthoxylum bungeanum are planted, they should be pruned in the same year or the next year, and the top should be cut off 25~30 cm away from the trunk, so as to germinate more side branches and make the tree more full and vigorous. At this time, the saplings are fragile, so pruning should be based on light cutting, not short cutting. After that, keep 5-7 branches sprouting at the base, and cut off all the others.

4. Stay strong and weaken

After 25 years of growth, Zanthoxylum bungeanum will enter the aging period. At this time, pruning mainly focuses on retaining the strength and concentration of nutrients to prolong the life of plants. It is necessary to cut off some twigs, drooping branches and aging branches from the base during the growth process, leaving strong branches to continue to grow, restore the tree's potential and grow again.
