First, pruning young forsythia must first cultivate the trunk, pruning the buds sprouting at the base and the branches at the lower part of the trunk. When the trunk grows to the required height, the top is cut off to promote the germination of lateral branches. After the equilateral branches grow, they need to be pruned two or three times to make the crown fuller. When pruning, it is only necessary to cut off the weak branches of the crown to promote the better growth of the lateral branches and help to expand the crown.

Second, middle-aged pruning is a period of vigorous plant growth. At this time, pruning is mainly to cut off the weak branches and leave only the strong branches. Pruning time is in spring and autumn. After the first frost in autumn, all the weak branches should be cut off, and the branches and leaves that are too dense should be thinned out. Every spring after the flowering period, there will be many new shoots sprouting, so it is necessary to properly pick dense shoots to promote better illumination and be conducive to growth.

Third, pruning forsythia in the elderly After years of growth, the whole state will gradually weaken and need to be pruned correctly. At this time, it is mainly retraction pruning, that is, cutting the perennial branches short to improve the illumination, thus saving a lot of nutrients and cultivating new branches. In addition, root pruning should be carried out to cut off some old roots, dead roots and rotten roots, so as to better absorb water and nutrients, promote new roots to germinate faster and help restore.

IV. Precautions In the management process of forsythia suspensa, not only should it be pruned correctly and timely, but also attention should be paid to maintenance. If you want it to bear more fruits, you need to replenish fertilizer in time. Only adequate nutrition can help growth and promote more flowers and fruits.
