Before planting large seedlings, the number of branches should be determined according to the height of seedlings, generally 2 ~ 3 layers are appropriate. This is not only beautiful in appearance, but also beneficial to the vegetative growth and root development of the tree because of its numerous branches and leaves.

For the shaped tree, we should pay attention to pruning a layer of whorled branches at the top of the trunk to ensure the absolute advantage of the extended branches at the top of the central trunk, and at the same time weaken and sparse the generated single whorled branches.

If the branches compete with the trunk because the branch potential is too large, pruning control must be carried out in time, and it must not be left unchecked to avoid branching trees.
