During the year, there are three main periods of time to prune osmanthus. The first stage is from March to April every year, when it grows new buds. The second period is from October to November, when the flowers are gone. The third period of winter dormancy is from January to February.
1. Pruning in early spring: when it grows new shoots in early spring, it needs to be pruned once. At this time, the dried branches on the plant should be cut off first, and then the top 3-5cm of the main branch should be cut off together with the new buds. This can promote its long new branches, so that it grows more dense
2. Pruning after flower: after its flower withers, it is necessary to immediately cut off all the remaining flowers on it. If there are diseased branches, they can be cut off at the same time. In this way, it can save more nutrients, which is very beneficial to its winter.
3. Winter pruning: in winter, it grows very slowly and is not easy to be injured by pruning. So you can do a heavy cut. At this time, you can cut off all the branches that are not growing well, cut the long branches short, and cut the branches that are too dense. This will be more beneficial to its growth in the next year.
