1. Winter pruning is generally carried out in1-February. During this period, Osmanthus fragrans has entered a dormant period. According to the age of the tree and the needs of plastic surgery, the branches that are too dense, too long, too prosperous, dead, pests and diseases are thinned. When the backbone branches need to be replaced, the old branches that are more than two years old should be taken back, and the long annual branches should be cut short to maintain a good tree shape. Dense internodes at the front end of osmanthus fragrans branches are easy to form whorled branches. Generally, it is appropriate to cut off 1/3 of the main branch extension branch.

2. Generally, the sprouting strips are removed during the growth period, and the latent buds near the ground are completely removed from the base to prevent the overgrowth. In particular, there are many sprouts of grafted seedlings, which need to be pulled out repeatedly to ensure the survival rate and normal growth of grafted seedlings.

3. Bud smearing is usually carried out in March-April in spring. Before the new shoots are lignified, the redundant branches and shoots are erased.

4. Picking is carried out in spring and summer. According to the tree type and the need of cultivating branches, pick some new shoots, control the length of branches, and promote the complete lignification of branches.

5. According to the needs of plastic surgery, after retaining the trunk, twisting other branches can slow down the growth and cultivate a thick trunk.
