1、 Reasons for flowering failure of Forsythia suspensa

1. Low self pollination fruiting rate: the flowering failure of Forsythia suspensa is likely to be caused by self pollination, and the self pollination fruiting rate will be very low, which can be about 4%. If you want it to bear more fruit, cross pollination is the only way. Family planting is generally difficult to complete. In open field cultivation, plants with long style and short style can be planted alternately, which can promote more results

2. Scattered nutrients of long branches: the branches and stems of Forsythia suspensa are very vigorous, and many long branches will sprout every year, which will not only have no ornamental effect, but also lead to the dispersion of nutrients in the branches, thus reducing the fruit rate. Pruning should be carried out in time, and the bare branches should be cut off to save nutrients, promote nutrient concentration and help it bear fruit

2、 Where does Forsythia grow and produce more results

Generally, Forsythia suspensa will bloom more and bear more fruits in places with sufficient sunshine and water. It has no excessive requirements for soil. Neutral soil, slightly acidic soil and alkaline soil can grow normally. However, if you want it to grow more vigorously and produce more results, you'd better choose a plot with sufficient fertility. In addition, regular fertilization should be carried out during the growth period, especially before flowering. With sufficient nutrients, flowering will be more, and the fruit setting rate can be improved
