It's better to prune when the spring comes. At this time, the branches just sprout, grow faster and consume more nutrients than the old branches. In addition, this time the plant grows vigorously, the plant wound healing ability is also relatively strong.
1. When the new branches of the plant grow to about 4cm, the new buds on the top of the plant can be removed to promote the growth of the nearby branches.
2. The plant is ready for the opening of flowers in summer. At this time, it is necessary to cut off the dense branches, because too many branches will block the penetration of light, and will consume too much nutrients. After pruning, it will be more conducive to bud sprouting.
3. After flowering and defoliation, prune the residual flowers and disorderly branches in time. In addition, prune the weak branches of the plant, which will help the plant to recuperate.
