In March and April, the dry branches of osmanthus fragrans should be cut off, and the top of its main branches should be cut off 3-5cm together with the new buds. June 10- 1 1, after it blooms, all the residual flowers and diseased branches on it should be cut off. 1-Long branches can be shortened in winter in February, and branches that are too dense can be thinned.

First, the pruning time

Osmanthus fragrans mainly needs pruning in three periods of the year. The first stage is from March to April every year, when new buds grow. The second paragraph is 10- 165438+ October, after its flowers wither. The third winter dormancy period is1-February.

Second, the pruning method

1, early spring pruning: when it grows new branches and buds in early spring, it needs pruning once. At this point, it is necessary to cut off the dry branches on the plant first, and then cut off the 3-5cm at the top of the main branches together with the new buds. This can promote it to grow more new branches, thus making it grow more densely.

2. Pruning after flowering: After its flowers wither, all the remaining flowers on the tree should be cut off immediately. If there are diseased branches, you can cut them off together. This will allow it to preserve more nutrients, which is very beneficial to it for the winter.

3. Pruning in winter: It grows slowly in winter and is not easy to be pruned. So you can cut a lot of wool. At this point, you can first cut off all its poorly growing branches, shorten the long branches, and trim off the too dense branches. This is more beneficial to its growth in the coming year.
