Root Rot

About this condition

A physiological disorder in which roots suffocate and decay due to overwatering or poor drainage, causing overall plant decline. It is considered one of the most common problems affecting foliage and rare plants.

Common symptoms

• Leaves may yellow and wilt or soften
• The stem base may turn brown to black and become mushy
• Roots may turn dark brown and emit a foul odor
• New growth may halt and overall plant vigor may decline

Common causes

• Watering too frequently or applying excessive amounts at once
• Use of poorly draining soil or containers without drainage holes
• Insufficient light slowing soil dryout
• Root-bound conditions reducing aeration and drainage

Prevention (growing conditions & routine care)

Water only after the topsoil has dried, giving a thorough soak until water drains from the bottom, then promptly emptying the saucer. Using well-draining soil and ensuring adequate light and airflow helps prevent root rot.
