How to prune Sophora japonica
Pruning time In order to grow better, Sophora japonica must be pruned separately in summer and winter.

Pruning method Pruning in summer: Summer is the most prosperous period for Sophora japonica. Pruning at this time is mainly to improve its tree shape and make it grow more ornamental. Pruning in summer is also essential. You can cut off the drooping branches growing this year and leave 1/4 or 1/3, which can promote the growth of its lateral buds and make the plants more lush. At the same time, prune too long branches to prevent their growth from consuming nutrients. You can also cut the trunk short to make more branches grow and other branches stronger.

Winter pruning: It can be said that summer pruning is to make its rise more beautiful, while winter pruning is to shape the whole tree. After all the leaves fall in winter, you can see the overall branch distribution more clearly. First of all, we must adjust the growth of the main branches. We can tie them with hemp rope and artificially change their original shape and direction. Too dense parts can also be weakened to make the whole tree look more symmetrical, and old, weak and sick branches and stems should be cut off. Generally, the parts left after pruning are thicker, so they should be burned or thrown away after pruning.
