In addition to ensuring the normal maintenance of bonsai survival, it is also necessary to maintain the shape by pruning. The pruning of black pine is mainly to pick buds. If it is just on the pot, it will not be picked for one year. Generally, buds will be picked in the spring of the following year after the branches and leaves are flourishing.

Bud taking should be carried out before needle drawing, and 1/2 of the terminal bud should be taken. If you don't need branches to grow, you can pick all the terminal buds.

In order to make the needles shorter and more beautiful, all the new branches that grew in that year can be cut off in July and August in summer, so that the new buds can germinate again around September. At this time, you can cut off the extra buds, leaving only two buds on both sides of the branch or in the horizontal direction.

In winter dormancy, black pine can be pruned once, and the branches that affect the shape can be cut off and sealed with wax or glue.
