1、 Prune branches and leaves

When it is found that it grows high, the most effective way is to trim its branches and leaves properly to prevent it from growing high. First of all, when pruning, give priority to cutting off its protruding branches, and then leave 4 to 5 bud holes, or leave about 10cm of branches and leaves, but all the branches and leaves in the upper part should be cut off. Secondly, when pruning it, it should not be limited to individual branches, but all branches should be pruned. At the same time, all the branches with poor growth should be cut off, so as to leave more nutrition for the good branches

2、 Curing after trimming

1. Proper watering

After it is trimmed, it cannot be sprayed with water and rain immediately to prevent the place where it is cut from rotting. It should be placed in a cool place in the room. If the light is too bright, it should be properly shaded and watered less. When watering, the amount of water should be half of that at ordinary times, because the leaves do not transpiration at this time, so little water is needed. If it is watered too much, its roots will rot, which will affect its recovery after pruning

2. Timely fertilization

Before the branch germinates, it needs to apply fertilizer to it in time. Here, nitrogen fertilizer is mainly used. And add some fungicides when watering to prevent the root from rotting. After about a month, branches will grow one after another, and leaflets will gradually elongate. At this time, normal maintenance can be carried out
