What should I do if Forsythia blooms but does not bear fruit? What is the reason for not blooming?

1. Reasons why Forsythia blooms but does not bear fruit

1. Low fruiting rate due to self-pollination

The reason why Forsythia only blooms but does not bear fruit is most likely due to self-pollination. The fruit-bearing rate of self-pollination is relatively low, basically maintained at around 4%. Especially when grown at home, cross-pollination is difficult, so the fruit-bearing rate is generally low.

2. Too much nutrients dispersed by long branches

There is no pruning during the maintenance period, and there are too many long branches, especially in spring. If not pruned, the long branches will disperse a lot of nutrients, causing the nutrients in the main body of the branches to be absorbed. The nutrients are too dispersed, which will lead to a decrease in the fruiting rate.

2. How to deal with Forsythia flowering but not bearing fruit

1. Promote cross-pollination: When planting, plants with long and short styles should be planted alternately. This can promote cross-pollination and help it to pollinate better, thereby increasing the fruit setting rate.

2. Reasonable pruning: Pruning should be carried out in time during management. When the plant is about 1 meter tall, the main shoots should be pruned in winter and the tips should be pinched in summer to promote more branches. If you find overgrown branches, sick and weak branches, or old and dead branches, you should prune them off to save nutrients and make them more concentrated, which can also increase the fruit set rate.

3. Reasonable fertilization: After pruning, topdressing is required. It can be applied with decomposed manure, or phosphorus and potassium fertilizers. Just dig holes and apply them around the plants. This will make the plants healthier and promote more flowering and fruiting.
