2. Pruning of strong trees: potted mature osmanthus trees, and cut off weak branches, too dense branches, cross branches, too prosperous branches, sick branches, old branches that cannot bloom, etc. , so that the main branches and lateral branches are distinct, the strong branches and weak branches are harmonious and unified, the branches are evenly distributed, and the tree is compact and full.
3. Although the pruning of weak trees is the same as that of potted osmanthus, due to improper maintenance and management or diseases and insect pests, its tree vigor is weak, the number of new branches is small, the growth of new shoots is small, the branches are slender and messy, and the number of diseased branches and dead branches is increasing. The leaves are light in color and have low ornamental value. Short-cut retraction pruning should be given priority to, combined with thinning appropriately. On the basis of keeping the original tree shape. We should strengthen water and fertilizer management, soil and water conservation and pest control to promote more new roots.
4. Pruning of old trees An old tree has been planted in osmanthus pots for about 50 years. For this type of tree, in addition to pruning like an adult tree, it should be pruned once every two years to squeeze the trunk and promote the germination of new branches at its base.
