How to propagate pepper trees and what to pay attention to

How to reproduce the pepper tree

The main ways of propagating Sichuan pepper trees are cuttings, division, and sowing. Its seeds can also be propagated, and its natural reproduction method is also seed propagation. Generally speaking, Sichuan pepper trees are propagated fastest by cuttings.

Breeding time of pepper tree

It is generally better to choose spring as the time for breeding of Sichuan pepper trees. The climate at this time is very mild and the temperature is relatively suitable, so the survival rate of breeding is high.

How to propagate pepper tree

Propagation of Zanthoxylum bungeanum by division

It is usually carried out in spring before the pepper trees sprout. Select tiller seedlings within two years and bury them in the soil. After they successfully grow roots, it will take about one growth cycle before the tiller seedlings can be separated for planting.

Cutting propagation of pepper tree

Cut one-year-old thick and uninjured branches of the Zanthoxylum bungeanum tree as cuttings, place the branches in an acetic acid solution to promote rooting, take them out and dry them, then insert the branches vertically directly into the prepared substrate.

Seeding propagation of pepper tree

When sowing, you need to first select plump seeds free of pests and diseases, germinate and disinfect them, and then sow them on the prepared soil. Generally, sowing is chosen in autumn, and the germination rate and uniform seedling rate are relatively high.

Things to note when breeding pepper trees

1. When propagating Sichuan pepper trees by cuttings, you need to be careful not to make the cut too large when cutting the branches. Try to keep it smooth to prevent wound infection and affect the survival rate of the cuttings.

2. When the Sichuan pepper tree is propagated by sowing, the seeds are relatively hard, oily and have poor permeability. If they are not processed, the germination rate is relatively low. Therefore, the seeds must be degreased and defatted before sowing to increase the germination rate.
