How to assist in pruning forsythia and how to improve fruit setting

1. How to perform auxiliary pruning

1. Pruning during the growth period: During the growth period, damaged and diseased branches should be pruned, leaving only healthy branches to save nutrients and promote more vigorous growth. When the buds sprout in spring, you should trim the dense buds and cut off the suckers that affect the tree's vigor. In addition, the branches should be cut short after flowering to promote the sprouting of new branches and make the tree shape fuller.

2. Pruning during the dormant period: The dormant period is after the leaves fall in autumn and winter, and pruning must be done at this time. Cut off dead, diseased, overgrown, and thin branches, and shorten thick branches. The parts with new buds can be left behind. Generally, three to five buds are enough on each branch. In addition, if the plant has been maintained for many years, it needs to be pruned back.

2. How to improve fruit setting

If you want to increase the fruit setting rate of Forsythia, you need to pay attention to two aspects. The first is to promote cross-pollination. If it is self-pollination, the fruit setting rate is usually only 4%, and the fruit setting rate will be higher if it is cross-pollination. When planting, it is recommended to plant plants with long and short styles separately to promote cross-pollination. The second is to carry out pruning in time, especially cutting off some overgrown branches and diseased and weak branches in time to reduce nutrient consumption and make nutrients more concentrated, which can also increase its fruit setting rate.
