Reasons for the Withering and Blackening of Bowl Lotus Leaves1. Water Quality Issues
Water quality is an important factor affecting the growth of bowl lotus.

3. Water Level Too High or Too Low
Water levels that are too high or too low will affect the normal growth of bowl lotus. High water levels can cause root hypoxia and lead to root rot, while low water levels will expose the leaves excessively to the air, causing them to wither and blacken.
