In the young stage, the main purpose is to cultivate the main trunk. The small buds that sprout at the base and the branches at the lower part of the main trunk should be pruned. After the side branches have finished growing, they need to be pruned two or three times to make the crown fuller. Pruning in the middle stage is to cut off diseased and weak branches and leave strong branches. Pruning in the old age is mainly retraction pruning, which means to shorten old perennial branches, and also prune old and dead roots to promote better germination of new roots.

1. Pruning at an early age

1. Pruning at the young stage

For Forsythia suspensa at the young stage, the trunk must be cultivated first, and the small buds sprouting at the base and the branches at the lower part of the trunk should be pruned. When the trunk reaches the desired height, cut off the top to encourage side branches to sprout. After the side branches have finished growing, they need to be pruned two or three times to make the crown fuller. When pruning, just cut off the weak branches of the crown to encourage better growth of the outer side branches and help expand the crown.

2. Middle-age pruning

The middle stage is the period of vigorous growth of the plant. At this time, pruning mainly involves cutting off diseased and weak branches, leaving only strong branches. Pruning time is in spring and autumn. After the frost in autumn, all diseased and weak branches should be cut off, and branches and leaves that are too dense should also be thinned out. After the flowering period every spring, many new branches will sprout. Dense branches and buds should be removed appropriately to promote better exposure to light, which is beneficial to growth.

3. Pruning in old age

< p>After many years of growth, the entire state of Forsythia will gradually weaken, so it must be pruned correctly. At this time, the main thing is to cut back the perennial branches, which means to shorten the perennial branches to improve the light, thereby saving a lot of nutrients and cultivating new branches. In addition, root pruning must be carried out, and some old, dead, and rotten roots must be cut off so that they can better absorb water and nutrients, promote faster germination of new roots, and help recovery.

IV. Precautions

When managing forsythia, you must not only prune it correctly and timely, but also pay attention to maintenance. If you want it to bear more fruits, you need to add fertilizers in time. Sufficient nutrients can help the growth and promote more flowers and fruits.
