1. Low fruiting rate of self-pollination: self-pollination is likely to be the cause of non-fruiting of Forsythia suspensa, and the fruiting rate of self-pollination will be very low, basically around 4%.If you want it to bear more fruit, you have to cross-pollinate it.Home planting is generally difficult to complete, in the open field cultivation can be long style and short style plants alternate planting, so that can promote more fruit.
2. Slender branches disperse nutrients: The branches of forsythia are very vigorous in growth, and many slender branches germinate every year, which not only has no ornamental effect, but also leads to nutrient dispersion of branches, thus reducing the fruiting rate.Pruning treatment should be carried out in time to cut off the long branches, save nutrients, promote nutrient concentration and help it bear fruit.
Generally, Forsythia suspensa will blossom more and bear more fruits in the place where there is enough sunshine and water.It does not require too much soil, neutral soil, slightly acidic soil and alkaline soil can grow normally, but if you want it to grow more vigorously and bear more results, it is best to choose fertile plots.In addition, regular fertilization during the growth period, especially before flowering, nutrients will be more enough to blossom, but also to improve the fruit setting rate.
