Likely causes
Poor Drainage
Most likelyHow to tell: The plant wilts despite having wet soil, and the stems feel mushy near the base.
What to do: Remove the plant from its pot and trim away any black, slimy roots. Repot into fresh, well-draining soil and a pot with drainage holes.
Overwatering
Most likelyHow to tell: The soil smells sour or musty and stays wet for more than 10 days.
What to do: Adjust your watering to only when the top inch of soil is dry. Never let the plant sit in a saucer full of water.

When to worry
If the roots are mostly black and mushy, the plant may be too far gone to save. If you find some healthy white roots, there is a good chance for recovery.
Stopping it coming back
Always use a potting mix that drains well and ensure your pot has holes at the bottom.

Questions people ask
- Can I save a plant with root rot?
- If you catch it early, yes. Trim the bad roots, repot in dry soil, and be very careful with water while it recovers.
- How often should I water to avoid this?
- Every 7 to 10 days is a good starting point, but always check the soil first. If the top inch is still damp, wait a few more days.
