The reasons for the falling flowers and fruits of plum trees

Plum trees are easy to turn into flowers, but they are often full of flowers and half fruit. More flowering, more nutrition consumption, serious fruit drop. There are generally three peaks of plum falling flowers and fruits: the first falling flower, starting from the completion of flowering, is mainly caused by anaplastic floral organ, loss of fertilization ability or unfertilized. The second drop occurs about 29 days after flowering. When the fruit is like soybeans (4488, 18.00,0.40%), the young fruit and pedicel turn yellow and fall off until the kernel begins to harden. This is mainly caused by poor pollination and fertilization. For example, lack of pollination trees, lack of pollinating insects, low temperature at flowering stage, pollen tube can not elongate normally and so on. The third fruit drop, also known as "June fruit drop", begins about 3 weeks after the second fruit drop, and the fruit drop is less. The main reason for fruit drop is lack of nutrition, embryo development halfway to stop, resulting in decay, resulting in fruit drop.
