There are only two ways to prune pine bonsai. One method is to pick buds, pick them in the spring growth period of pine trees, remove the strong branches and keep the weak branches to keep the growth balance. The other is pruning, which is carried out during the dormant period from 10 to February of the following year. Too messy and weak branches can be cut off.

There are more than 80 kinds of pine trees in the world, which are not only numerous, but also widely distributed, such as Pinus tabulaeformis and Pinus sylvestris var. mongolica. Pinus sylvestris var. mongolica, Pinus thunbergii and Pinus densiflora distributed in several provinces of North China and Northwest China, Pinus massoniana, Pinus taiwanensis, Pinus alpine, Pinus Bashan, Pinus Taiwan Province and Pinus brevifolia in the Qinling-Bashan Mountains of Central China are mostly the main tree species for afforestation in barren hills in China.
