Bury Zanthoxylum bungeanum and Zanthoxylum bungeanum at the root, and it will die unnoticed (the number depends on the size of the tree). If you want the tree to die early, you'd better bury the pepper now, because there are no new buds and it will die faster. For small trees, the best way is to cut off the roots and bury them in the wound, and the big tree can dig a hole and throw it in.
