Chimonanthus praecox is usually pruned after flowering to remove dead branches, too dense branches, cross branches, pests and diseases. The annual branches are all cut off except for 2-3 pairs of buds at the base to promote germination and branching. After each new branch grows 2-3 pairs of leaves, it is necessary to pick the heart to promote the flowering branches to be short and strong, so that the plant shape is symmetrical and beautiful. Pruning is mostly carried out in March-June and stopped after July. If pruning is not timely, it is easy to produce many branches. Consume nutrition; Poor flower bud differentiation affects flowering.
