1. Causes of Rainbow Bush dropping its leaves

1. Sunscorch

Rainbow Bush likes a sunny environment and is fairly drought-tolerant. If it cannot get sunlight for a long time, the variegated colors on the leaves will fade, the distance between stem nodes will lengthen, and the plant will become loose and not compact, affecting its ornamental value. However, if it is exposed to scorching sun in summer, it very easily drops its leaves.

2. Black rot

Black rot is one of the most common diseases in succulents, usually a fungal infection caused by overwatering or an overly humid growing environment. It generally causes symptoms such as leaves becoming soft and leaves dropping.

3. Water

Both lack of water and excess water can cause leaf drop. The difference is that lack of water not only causes leaf drop, but the leaves will also become wrinkled. If it is only dropping leaves and the leaves are not wrinkled, then it is not lack of water and may be caused by too much water.

4. Adjustment after repotting
