When does Lagerstroemia indica pull branches?

May-10 month. According to the modeling needs of Wei Zi bonsai, the branches of Wei Zi bonsai were adjusted, and the angles of the branches were increased and controlled, and the directions of the branches' positions and angles were adjusted at will, so that the nutrients were concentrated and accumulated. Especially, after some branches of Wei Zi bonsai were pulled, braced and held, some branches arched, and several extremely short flower branches (within 10 cm) grew on their arched backs, which not only greatly increased the number of flowering branches and buds, but also greatly increased the number of flowers.
