🌱 How to Care for China Doll Plant to Prevent Damping Off?

💧 How to Water

Water when the top inch of soil feels dry. Keep soil consistently moist during spring and summer, reducing frequency in fall and winter. Ensure excellent drainage to prevent root rot — never let the plant sit in standing water.
