1、 Bending main branch

Generally, adult black pine is difficult to dwarf. Only the plants with small age and strong plasticity can be dwarfed. They can be dwarfed by bending the main branches and fixing them with iron wire. At the same time of binding, the side branches that grow too high can be cut off to control the height. However, be careful not to cut off all its leaves, otherwise it will not survive

2、 Carry out bud picking

After fixing its main branch, it should be trimmed regularly. In the growing season, we should cut off the leaf buds regularly. This can greatly slow down its growth speed and prevent it from growing tall. At other times, cut off the branches that grow too high in time to control its height

3、 Cutting

If you don't have young plants on hand, you can also cultivate new and shorter plants by pruning and replanting. The specific method is to select healthy branches, cut them obliquely at the low end and insert them into loose soil. Then put it in a warm place and maintain it slowly. After it grows branches and buds, it can be cultivated into a short and strong plant type by fixing it with iron wire
