The first stage is from March to April every year. At this time, the climate temperature will gradually increase and the plants will grow fast. Pruning can promote osmanthus trees to sprout more new buds, which is beneficial to the vigorous growth and flowering of plants. When it grows new buds, it is necessary to cut off the dry branches of osmanthus fragrans at this time, and cut off the top 3-5cm of its main branches together with the new buds.
The second stage is June 10- 1 1. After cutting flowers, all residual flowers and diseased branches should be cut off, such as weak branches, withered old branches and too dense branches, and the main branches should be topped to control the growth height of plants.
The third stage is the winter dormancy period, that is, in June 5438+10-February, the longer branches can be shortened, and the branches that are too dense can be thinned to prevent the osmanthus trees from growing in vain, reduce nutrient consumption, and concentrate nutrients on the plants to make them grow stronger.
Targeted pruning according to different needs.
Osmanthus fragrans mainly includes four categories: Jingui, Yin Gui, Sijigui and Dangui, and the pruning methods are six aspects: sprouting removal, bud smearing, core removal, tip twisting, pruning, retraction and drying.
For osmanthus trees that are extensively managed, it generally includes cutting short, cutting off dead branches and diseased branches, and cutting off withered flower branches, mainly pruning in dormant period, supplemented by pruning in growing period.
According to the needs of plastic surgery, after retaining the trunk, twisting the tips of other branches can alleviate the growth potential and cultivate a strong trunk.
