1, pruning time. When pruning plants, the growth patterns in different periods are different. Generally speaking, spring is the key time of plant growth, and many small buds begin to grow, so we should pick them. Pruning is suitable for the dormant period of plants, that is, 10 to the next February when the growth of pine bonsai stops completely.

2. Pruning technology. In the early stage of growth, picking buds is the best way to regulate growth. The first thing you need is to suppress the branches that are too strong, remove most of the buds on the branches that are too strong, and then remove the useless weak branches according to the needs of appearance to balance the growth speed of the strong branches and the weak branches. Because pine trees are easy to flow gum after being injured, the sprouting ability of branches is weak, so pay attention to fine-tuning when pruning, and it is not advisable to over-prune. The main pruning targets are only those old branches that have not died of illness. It should be noted that pine trees are dormant before pruning, otherwise it will easily lead to plant death. After pruning, the fracture should be sealed with tape to avoid excessive glue flow.
