Pruning walnut trees should generally be carried out in the growth period, and try not to prune them at other times. Pruning during dormancy will accelerate the loss of water and nutrients, thus accelerating its death.

2. Pruning technology

Pruning walnut trees requires cutting off some annual branches, followed by cutting off the extended branches of side branches, cutting off some perennial branches, and then pruning too dense branches.

Pruning can start from the bottom of branches, and when long branches germinate, they should be cut off in time. In addition, cross branches and overlapping branches should be cut off. Some branches are thin because of insufficient light, so they need pruning.
