1、 Juvenile pruning

Young Forsythia suspensa should first cultivate the trunk, and the small buds germinating at the base and the branches at the lower part of the trunk should be trimmed off. When the trunk grows to the desired height, cut off the top tip to promote the germination of lateral branches. After the lateral branches grow, they should be trimmed two or three times to make the tree crown fuller. When pruning, just cut off the weak branches of the crown, promote the lateral branches to grow better and help expand the crown

2、 Middle age pruning

The middle age is the vigorous period of plant growth. At this time, pruning is mainly to cut off the sick and weak branches and leave only the strong branches. The pruning time is in spring and autumn. After the frost falls in autumn, the sick and weak branches shall be cut off, and the over dense branches and leaves shall also be thinly cut. Many new branches will sprout after the flowering period every spring. The dense branches and buds should be properly removed to promote better light, which is beneficial to growth

3、 Aging pruning

After growing for many years, the whole state of Forsythia will slowly weaken. It needs to be trimmed correctly. At this time, it is mainly retraction pruning, which is to cut the perennial branches short and improve the light, so as to save a lot of nutrients and cultivate new branches. In addition, root pruning should be carried out to cut off some old roots, withered roots and rotten roots, so as to better absorb water and nutrients, promote faster sprouting of new roots and help recovery

4、 Precautions

During the management of Forsythia suspensa, we should not only prune correctly and timely, but also pay attention to maintenance. If you want it to bear more fruits, you need to supplement fertilizer in time. Only with sufficient nutrients can it help grow and promote more flowers and fruits
