Check these first
- Feel the soil to see if it feels swampy or waterlogged.
- Check the drainage holes to ensure they are not blocked.
- Gently pull the plant out to inspect the roots for a foul smell.
Likely causes
Overwatering
PossibleHow to tell: The leaves will turn yellow and droop even though the soil is wet. The roots will look brown and mushy instead of firm and white.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the roots are badly damaged, trim the mushy parts and repot in fresh, well draining soil.
Poor Drainage
PossibleHow to tell: Water sits on the surface of the soil for a long time after watering. The plant looks stunted and unhappy despite your care.
What to do: Ensure your pot has drainage holes at the bottom. Mix in some perlite or sand to improve the soil structure and allow excess water to escape.

When to worry
If the base of the stem feels soft or mushy, the rot has likely spread too far. If the leaves are just slightly drooping, you can usually save it by adjusting your watering.
Stopping it coming back
Only water when the top inch of soil feels dry and always empty the saucer under the pot after watering.
