1、 What should I do

It is generally caused by watering, fertilization and sunshine, which can be solved according to the situation:

1. Watering: if too much water is applied, there will be accumulated water in it for a long time, and there will be no oxygen in the soil. The roots can't breathe in it, and some small fibrous roots will rot. If there is a long-term lack of pouring and the supply exceeds the demand, it will also lead to. In the former case, it can be stopped immediately and the soil can be loosened to make the water seep out as soon as possible. In the latter case, move to a cool place and gradually increase the moisture

2. Fertilization: the application of fertilizer has no scruples about the growth of good plants, especially too much nitrogen fertilizer, which is very easy to cause. If you forget about fertilization or do not change the pot soil for a long time, it will lead to the lack of nutrition inside, which will make the branches and leaves become thin and weak. In the former case, stop immediately and increase the water volume. In the latter case, new basin soil can be replaced, and thin fertilizer can be applied after adaptation

3. Sunshine: too strong sunshine can scorch leaves and turn yellow. Curing at places with insufficient light will cause the leaves to become thin and yellow. In both cases, the position can be changed and placed in a place with astigmatism for maintenance

2、 How to deal with falling

For the sake of beauty, the fallen leaves can be removed, and then see if they have suffered from diseases and pests, and spray them in time
