1. If it is caused by too much use when replenishing nutrients, the simplest way is to carry out a lot of irrigation, but it is appropriate to ensure that all the water flows out, so as to prevent the root of the plant from rotting instead of diluting the fertilizer. The best way is to replace the soil, so that the leaves can recover after curing for a period of time

2, winter temperature is relatively low, especially in the South without indoor heating, so it is necessary to properly heat up the plants, put plastic bags around their bodies, or cover them with foam boxes for warmth. But in summer, the temperature is relatively high, so it's better to move it to a windy and cool place

3. Don't let it see particularly exciting light. Plants can't be exposed to such light. If the exposure is serious, it is difficult to recover, but if the exposure of the sun is not very strong, you can move it to a cool place for maintenance for a period of time, and it will gradually recover its original appearance

4. The amount of water determines the yellowing degree of leaves. If it is caused by too much, it needs to be replaced and replanted immediately. If it is caused by water shortage, it needs to be replenished in time to solve the state of thirst
