Hello, 1, potted plant pruning and plastic surgery. Potted plants are usually pruned to dryness. Starting from the seedlings, select a trunk, and when the trunk reaches a predetermined height, put it on top to make it sprout 3-5 lateral branches to form a crown. After that, pruning is carried out once a year before germination in winter and spring, and diseased dead branches, over-dense branches and thin and weak branches are cut off, and plants with strong upper part and weak lower part and poor tree shape are appropriately shortened to promote adventitious bud germination and grow new branches. But pruning should not be excessive, otherwise it is easy to sprout branches and affect the number of flowers.

2, ground planting pruning and shaping. One is high-level plastic surgery. When the small tree grows to 1 m high, top it to make it grow three lateral branches. When the lateral branches grow to a certain length, one on top of the other, so that the three lateral branches are divided into three or so branchlets, a full crown can be formed. The other is spherical plastic surgery. Osmanthus fragrans (especially Osmanthus fragrans) has a strong ability to naturally form shrubs. As long as it is properly trimmed, a spherical crown can be formed.

Deformed trees are trimmed and reshaped. Osmanthus fragrans will grow into a deformed tree if it is not pruned and shaped for a long time. For this kind of trees, the following pruning methods can be adopted: ① For plants that grow very tall and lack branches and leaves at the lower part, the trunk can be cut off by more than 2/3 or 3/4 to promote new branches from the lower trunk. In the coming year, it is found that long branches, dislocated branches and other random branches should be cut off to form a full and natural shape. ② For top-heavy and overgrown trees, the upper strong branches of about 1/4 should be pruned every year. When planting pruning and shaping on the ground, dense branches, sparse branches, branches of diseases and insect pests, long branches and old branches that cannot bloom should be cut off at the same time to facilitate ventilation and light transmission. Water and fertilizer management should be strengthened for all the sweet-scented osmanthus trees after pruning and shaping. After shaping, it is found that there are clustered buds at the base or middle of the trunk, and the buds should be erased in time.
