Root Rot in Houseplants: Causes, Prevention & Last-Resort Recovery

Houseplant Root Rot

What Is Root Rot?

A condition caused by overwatering and poor drainage. Excess water displaces oxygen in the soil, suffocating roots and allowing decay fungi to take hold. Severe cases are often fatal.

Warning Signs

• Wilting despite wet soil
• Yellowing, dropping leaves
• Mushy, brown/black roots with a foul odor
• Plant loose in pot

Prevention (The Only Real Cure)

• Always use pots with drainage holes.
• Never let plants sit in water more than 10 minutes—empty saucers.
• Use light, fast-draining potting mix.
• Water only when the top inch (or more, per species) is dry.
• For moisture-loving plants, keep soil evenly moist but never soggy.

If Root Rot Strikes

1. Remove plant from pot; wash roots gently.
2. Trim all mushy, dark roots with sterile scissors.
3. Repot in fresh, sterile mix in a clean pot with drainage.
4. Water sparingly and hope for recovery—success is not guaranteed.

Prevention is far easier than cure. Make drainage a habit.
