1. Osmanthus trees need to be pruned in spring. Pruning of osmanthus trees in spring has many benefits.

2. Shaping and pruning is an important measure to cultivate single-stemmed osmanthus trees. Through pruning, the nutrients of the tree are redistributed in a planned way, so that the overly dispersed nutrients are concentrated and supplied to a certain growth center. To cultivate single-stemmed osmanthus trees, pruning must be carried out promptly and reasonably to make the tree structure reasonable. Forming a single trunk allows branches and leaves with strong assimilation ability to grow in favorable positions on the trunk, prompting a large amount of nutrients to be used for the growth of the thickening of the trunk. Regulate and control the contradiction between trunk and crown growth, flowering and vegetative growth, growth and senescence and renewal. And can make it grow into the required tree shape and reach the ideal height. It can also reduce pests and diseases, thereby making the sweet-scented osmanthus grow faster and have straight trunks. The tree shape is beautiful and meets people's viewing requirements. Achieve the effect of beautifying the environment.
