2. How to deal with forsythia flowering but no fruiting

Its failure to bloom may be caused by self-pollination. It is necessary to encourage cross-pollination to increase the fruit setting rate. When planting, plants with long styles and short styles should be planted alternately. It may also be caused by improper pruning, which cannot be pruned in time during the management period. The long branches will disperse nutrients and reduce the fruiting rate. It should be pruned reasonably, and it is best to fertilize appropriately after pruning. Only with sufficient nutrients can it promote flowering and produce more fruits.

1. Reasons why Forsythia forsythia flowers but does not bear fruit

1. Low self-pollination fruiting rate

Forsythia forsythia only flowers but does not bear fruit, which is most likely caused by self-pollination. The fruiting rate of self-pollination itself is relatively low, basically maintaining around 4%. Especially when grown at home, it is difficult to cross-pollinate, so the fruiting rate is generally very low.

2. Too many nutrients dispersed by long branches< /p>

There are too many leggy branches if they are not pruned during the maintenance period, especially in spring. If they are not pruned, the long branches will scatter a lot of nutrients, causing the nutrients in the main branches to be absorbed and the nutrients will be too much. Dispersion will lead to lower results.

2. How to deal with forsythia flowers and fruitlessness

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

2. Reasonable pruning: It should be carried out in a timely manner during the management period Pruning treatment. When the plant is about 1 meter high, the main tips should be pruned in winter and topping in summer to encourage more branches. Usually, if you find leggy branches, diseased and weak branches, and dead and old branches, you should also prune them to save nutrients and make the nutrients more concentrated, which can also improve its fruit setting rate.

3. Reasonable fertilization: Top dressing is required after pruning. For treatment, just apply decomposed manure, or mix it with phosphorus and potassium fertilizers, dig holes and apply them around the plants, so that the plants will grow healthier and encourage more flowers and fruits.
