Check these first
- Smell the soil for a foul, swampy odor.
- Check the drainage holes to make sure they are not blocked.
- Gently lift the plant to inspect the roots for mushiness.
Likely causes
Poor Drainage
PossibleHow to tell: The leaves turn yellow and drop, and the soil smells sour or musty. The roots will look mushy and dark instead of firm and white.
What to do: Repot the plant into fresh, well-draining soil and trim away any black, slimy roots. Ensure the new pot has plenty of drainage holes at the bottom.
Overwatering
PossibleHow to tell: The soil remains wet for more than a week, and the plant looks wilted despite the damp earth. This prevents the roots from getting the oxygen they need.
What to do: Wait until the top inch of soil is dry before watering again. Adjust your schedule to ensure you are only watering every 3 to 7 days as needed.

When to worry
Worry if the stem base feels soft or mushy, as this indicates the rot has spread to the main structure. It is normal for a few lower leaves to drop occasionally as the plant grows.
Stopping it coming back
Always use a fast-draining potting mix and never let the pot sit in a saucer of standing water.

Questions people ask
- Can I save a plant with root rot?
- Yes, if you catch it early. Trim the dead roots, repot in fresh soil, and water sparingly until you see new growth.
- Does the pot size matter?
- Yes, a pot that is too large holds too much water, which keeps the soil wet for too long. Use a pot that is only slightly larger than the root ball.
