Pruning method of Sophora japonica in winter

Sophora japonica only needs to prune dense branches, diseased branches and dead branches. When the crown is unbalanced, the branches of the excessively high part should be contracted or shortened.

Winter pruning should pay attention to avoid cold weather. Pruning when the temperature is too low will sap the wound and affect the recovery of trees. Therefore, winter pruning should be carried out before the weather gets warmer in early spring and the roots enter vigorous activities. Because the roots have already entered the growth period before sprouting on the ground. At this time, nutrients returned to the roots after autumn began to be transported upward from the roots for the needs of spring flowers to germinate and bloom.
