Cause: if you don't water for a long time during cultivation, the plant is in a state of water shortage, the root system can't normally transport water to the leaves, the leaves can't absorb water, and it will turn yellow after a long time
Solution: we should water the basin soil in time to create a slightly wet growth condition for it. Every time we water it, we should water it thoroughly to ensure that the water is sufficient.
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, the leaves will turn yellow and fall. On the contrary, the growth environment for a long time can not see the sun, the leaves can not form melanin, will also appear yellow phenomenon.
Solution: if it is caused by lack of light, move to a place with good light. If it is caused by strong light, it should be transferred to a cool place for a period of time.
Reason: if you do not apply fertilizer for a long time during cultivation, the new and old leaves of the plant will turn yellow due to lack of nutrients
Solution: should be appropriate to supplement fertilizer, not for a long time without fertilization, should be thin fertilizer, can be appropriate to apply more nitrogen
