How to Save Monstera from Root Rot — Step-by-Step Recovery

Your Monstera has root rot but it is not too late. Learn how to identify, treat, and prevent root rot in Monstera deliciosa with this complete rescue guide. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Root rot is caused by overwatering, poor drainage, or compacted soil that stays soggy. Healthy Monstera roots are firm and white or tan — rotting roots are brown, black, and mushy. Early signs include yellowing lower leaves, mushy stems at soil line, and a sour soil smell. Severe root rot can kill a Monstera in weeks if left untreated. Prevention is easier than cure — proper watering habits and soil mix are essential. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: Overwatering is the primary cause — Monstera should dry out partially between waterings. Pots without drainage holes trap excess water and create anaerobic soil conditions. Heavy potting soil retains too much moisture around roots. Cold temperatures slow evaporation and root activity, increasing rot risk in winter. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Remove the plant from its pot and gently wash all soil off the roots with lukewarm water. Cut away all brown, black, or mushy roots with sterilized scissors — leave only firm white roots. Soak remaining roots in a dilute hydrogen peroxide solution (1 part 3% H2O2 to 4 parts water) for 10 minutes. Repot in fresh, well-draining aroid mix (orchid bark, perlite, peat) in a pot with drainage holes. Water sparingly for 2-3 weeks while the plant recovers — mist leaves to reduce stress. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
