1、 Lack of moisture

Reason: if you don't water for a long time during breeding, the plant is in a state of water shortage, and the root system can't normally transport water to the leaves. The leaves can't absorb water, and they will turn yellow over time

Solution: water the basin soil in time to create a slightly wet growth condition. Water it thoroughly every time to ensure sufficient water

2、 Light discomfort

Reason: the plant is not suitable for growing in too dark or strong light. If the maintenance position is not suitable, let the plant grow in strong light, and the leaves will turn yellow and fall. On the contrary, the growth environment can not see the sun for a long time, the leaves can not form melanin, and there will also be yellowing

Solution: if it is caused by lack of light, move to a place with good light. If it is caused by strong light, it needs to be transferred to a cool place for curing for a period of time

3、 Lack of nutrients

Reason: if no fertilizer is applied for a long time during breeding, the new and old leaves of the plant will turn yellow due to lack of nutrients

Solution: fertilizer should be supplemented appropriately, not without fertilizer for a long time. Thin fertilizer should be applied frequently, and some nitrogen fertilizer can be applied in an appropriate amount
