1、 The reason why the leaves fall when touched

1. Low temperature: it is very suitable for high temperature and can not withstand the invasion of low temperature. When the temperature changes from warmer to lower, the tissue of the leaves will be damaged, or a cold wind will blow, resulting in falling. Especially in the late summer to autumn, this phenomenon will become very obvious

2. Excessive nutrients: not according to the specific growth of the plant, too much nutrients are applied, and the root of the plant cannot be absorbed, or the root can be burned directly. It will also make the edge of the leaf charred and white. In the long run, the leaf will fall down if it touches

3. Too much water: its drought resistance is very strong. If you apply water all the time or pour some water every three or five times during a period when the water demand is not very large, it will make the basin soil very wet. The root has been living in such an environment. It will rot and the leaves will fall down if they touch it

2、 How to remedy it

1. Take thermal insulation measures in winter to maintain the temperature at about 15 degrees to avoid the invasion of cold wind

2. Suspend fertilization and add some watering so that the fertilizer can flow out naturally

3. Stop watering and put it in a place with good light and ventilation
