Pocket BotanistCheck these first
- Smell the soil for a musty or rotten odor.
- Check if the pot has drainage holes at the bottom.
- Gently lift the plant to see if the roots are mushy.
Likely causes
Overwatering
Most likelyHow to tell: The fronds turn yellow or brown and collapse, and the soil stays wet for days. The roots will look mushy and dark instead of firm and white.
What to do: Remove the plant from its pot and trim away any black, slimy roots. Repot the fern in fresh, well draining potting mix and a pot with drainage holes.
Poor Drainage
PossibleHow to tell: Water pools at the bottom of the pot or the soil remains heavy and dense. This prevents oxygen from reaching the roots.
What to do: Ensure your pot has holes at the bottom. Use a mix that includes perlite or orchid bark to improve airflow around the roots.
When to worry
Root rot is always a serious concern that requires immediate intervention. If the entire root system is mushy, the plant may not be salvageable.
Stopping it coming back
Always empty the saucer after watering so the plant never sits in standing water.

Questions people ask
- Can I save a plant with root rot?
- If you catch it early and remove all the decayed roots, you can often save the plant. It will need time to recover in fresh soil.
