1、 Pruning method

1. Bare long branches: when pruning in summer, it is mainly to trim some branches with long growth, and properly cut the long branches. The purpose of this is to reduce the loss of nutrients and promote better flowering later

2. Useless branches: some plants do not grow well, and there will be dry, thin and dense branches. Such unhealthy branches should also be cut off at this time, and the denser branches should be thinned properly

3. Pest branches: it is easy to suffer from pests and diseases in summer. Once they are invaded, they should be cut off as soon as possible, and the damaged parts should be cut off. When pruning diseased branches, be careful not to let bacteria infect the pruning mouth

2、 Precautions

1. The scissors used for pruning should be disinfected first, because after pruning, the plant is very weak and easy to be infected by bacteria, so the pruning tools should be clean enough

2. After pruning, it is necessary to maintain reasonably, and finally do not let the position of the wound come into contact with water. In summer, the climate is muggy and humid. After touching water, it is easy to be infected and black rot occurs
