How to prune walnut trees
Spring pruning refers to the pruning of walnut trees after germination, and the earlier the pruning, the better. As the temperature rises, after the tree germinates, the nutrients stored in the roots are continuously transported upwards, and the nutrients begin to transform. This time is also a time when trees need more nutrients, so when pruning, there is less bleeding and some nutrients will be lost. If a large part of nutrients are pruned too late, the tree will weaken, the yield will be affected, the quality will be reduced, and the income will be reduced.

There are also 20-25 meters high, with shorter trunks and wider crowns than other species. Bark is grayish green when young, grayish white when old, and shallow longitudinally. Branchlets glabrous, shiny, peltate glands, grayish green, and later brownish.
