1、 Pruning treatment

Stage 1: a large-scale pruning shall be carried out in spring. According to the overall growth of the plant, all thin branches, dry branches, overlapping branches and branches damaged by diseases and insect pests shall be pruned

Stage 2: when the plant grows luxuriantly, it needs to be pruned again, mainly cutting off the top tip, so that it can better grow new branches and pregnant buds, which will make it bloom more vigorously

Stage 3: when the newly grown branches and leaves have three sections, they need to pick the heart for it and control its growth height. In addition, the dense branches should be properly thinned to enhance the air permeability of the plant

Precautions: if it is cultured in the south, it should be disinfected after pruning to avoid being infected by bacteria

2、 Balanced nutrient

When fertilizing it at ordinary times, the nutrients are unbalanced, and the plants will grow wildly. For example, the amount of nitrogen fertilizer is relatively large, and the amount of phosphorus and potassium fertilizer is less. Therefore, we need to control the content of nitrogen fertilizer and appropriately increase the application of phosphorus and potassium fertilizer. We must be balanced in daily fertilization to avoid applying too much fertilizer of a certain content
