1、 Avoid exposure to the sun

Cause of occurrence: in summer, when the sun is too strong, the plants are exposed to the sun without any shelter. In serious cases, they wither and fall

Solution: change the pots and move the plants to avoid exposure to strong light, or block them with something to alleviate the stimulation of sunlight

2、 Supplementary light

Cause: the plant grows in a dark environment for a long time, and the leaves can't contact the normal sunlight and can't maintain growth. The leaves on the whole plant will begin to turn yellow and then fall off

Solution: put it in a place that can be exposed to the sun, and supplement the light can alleviate it

3、 Reduce watering

Cause of occurrence: if too much water is poured at ordinary times, the root system will rot, nutrients will not be supplied, and the leaves will fall off naturally

Solution: if the situation is not very serious, stop watering after finding it, or change watering to water spraying. If the situation is very serious, you need to trim the rotten roots

4、 Proper watering

Cause: the plant did not apply water for a long time, so it could not get the normal demand

Solution: apply water appropriately according to the plant growth
