Monstera Root Rot: Signs, Causes and How to Save the Plant
Quick answer: Monstera root rot is usually associated with roots remaining wet and oxygen-poor long enough for tissues to decay. Common signs include yellowing, limp growth, wet soil that does not dry, a sour smell, and roots that are dark, soft, or mushy rather than firm.

- Plant wilts even though the mix is wet
- Potting mix smells sour or stagnant
- Roots are soft, dark, or easily peel apart
- Stem base begins to soften
What healthy Monstera roots should look like
Healthy roots vary in color depending on age and soil, but they should generally feel firm. Root color alone is less useful than texture and smell.
How to save a Monstera with root rot
- Remove the plant from the pot and gently clear away enough mix to inspect the roots.
- Use clean cutting tools to remove clearly soft, collapsing roots.
- Clean the container or choose a clean pot with drainage.
- Repot into a fresh, airy mix that drains well.
- Water appropriately after repotting, then allow the mix to partially dry before watering again.
- Place the plant in suitable bright indirect light so it can recover without harsh sun.
Should you use a smaller pot?
If a large amount of the root system was lost, an oversized pot can hold too much wet soil around the remaining roots. Choose a container that matches the reduced root mass reasonably well.
What causes Monstera root rot?
Common contributing factors include watering too frequently, a dense mix, poor drainage, an oversized pot, very low light, and cool conditions that slow drying.
Can you propagate a Monstera to save it?
If rot has reached much of the root system but healthy stem and nodes remain, taking healthy cuttings can preserve the plant. See our houseplant propagation guide.
Monstera root rot FAQ
Can root rot happen without overwatering?
Yes. Poor drainage, dense soil, a large pot, low light, and cool conditions can all keep roots wet too long even if watering is not extremely frequent.
Should I fertilize after root rot?
Usually not immediately. A damaged root system needs to recover before normal feeding resumes.
