1、 Cause

1. It may be because the plant was exposed to too strong light during summer maintenance, and its tissue was too fragile to accept. Therefore, the leaves were burned and fell off in advance

2. It may also be because the amount of water given is improper. If more water is given, its roots will be soaked and damaged, and the natural leaves will fall. If less water is given, the plant will lack vitality and be blown by the wind

3. If there is too much fertilizer, the plant cannot absorb it and the concentration is too high, it will burn its roots, so the leaves can not grow normally

2、 What should I do

1. If it is due to the problem of light, it is necessary to timely transfer the plant to a well ventilated area, and it is best to temporarily only accept the maintenance of scattered light and let it self regulate for a period of time

2. If the amount of water is not enough, you need to control it well. If you give more, you can bask in the sun, and if you give less, you can make it up. If the root system is soaked bad, you can change the basin for treatment

3. If the fertilizer is too much, you can add water to dilute it, and then place it under well ventilated light for irradiation
