1. Pruning young macadamia trees is mainly carried out in winter. Pay attention to the fact that each pruning should not be too large, and the cut branches should not exceed one-third of the crown, so as not to affect their growth. When pruning, it is necessary to prune the lateral branches below 7cm, the lateral branches extracted from rootstocks and the branches affected by pests and diseases.

2. When macadamia nuts are pruned in winter, the diseased branches and dead branches are pruned in order to increase the nutrients of trees and increase the yield of fruits. When they are pruned in autumn, they are pruned in order to promote the lighting effect of trees and the ventilation between branches, so that trees can better balance their growth and prolong their life.
