1、 Cause

1. Improper watering: it needs reasonable watering in the maintenance of trigonometry plum. Once it is not watered for a long time, the soil will be very dry, which will affect the growth, and the leaves will turn yellow and fall off when touched. Watering too much will also lead to this problem. Ponding will cause rotten roots, unable to transport water and nutrients normally, and will also make the leaves wilt and fall

2. Lack of sunshine: triangle plum has a great demand for light. If it is kept in a place with poor light for a long time, it will lead to thin branches, yellow leaves, withering and falling

3. Diseases and insect pests: unreasonable maintenance may lead to diseases and insect pests, which will also cause this situation

4. Excessive fertilization: although it needs nutrients, too much fertilization is not conducive to growth. On the contrary, it will burn roots and cause leaves to turn yellow and fall

2、 Solution

1. Reasonable watering: pay attention to correct watering during maintenance and timely water supply during growth period, but not too much. Excessive watering should be placed in a well ventilated place to promote evaporation

2. Supplement sunshine: do not make triangle plum lack sunshine. Keep it in a place with good light and see light fully during growth

3. Prevention and control of diseases and insect pests: pay attention to ventilation at ordinary times, strengthen the prevention and control of diseases and insect pests, cut off the leaves of diseases and insect pests after discovery, and then spray chemicals

4. Watering and dilution: during maintenance, fertilization should be carried out according to the growth. After fertilizer damage is caused, watering and dilution should be carried out immediately to dilute the fertility in the flowerpot
