1、 Normal metabolism

Reason: its leaves wither and fall, which may be a normal growth and metabolic process. All plants have a metabolic process, followed by the yellowing and falling off of old leaves, which makes room for new leaves

Solution: if the leaves dry and fall due to this phenomenon, you don't need to worry too much. You can leave it alone and let it fall naturally. Or just take off the old leaves

2、 Reduce light

Reason: although it likes light, if it is placed in a place with strong light for a long time, it will be sunburned under the hot sun, resulting in yellow leaves and fallen leaves

Solution: do a good job in shading and move to the astigmatism in time. Especially the hot summer sun should be covered or removed in time. In addition, in the hot sun, we should often spray more water around the plant, so as to enhance the humidity and reduce the temperature

3、 Lack of moisture

Reason: its leaves wither and fall, which is likely to be caused by water shortage. The soil is dry and white. If it is not watered in time, the rhizome will be short of water. Naturally, it can not provide water for the leaves. After a long time, it will naturally dry and fall off

Solution: water once as soon as possible to wet the soil and roots. In the later stage, if the soil is dry, replenish water in time, especially in the flowering period, and try to increase the humidity as much as possible
