- Lift the pot to see if it is sitting in a pool of water.
Likely causes
Waterlogged soil
Most likelyHow to tell: The soil feels soggy or smells sour, and the plant looks wilted despite having damp soil.
What to do: Stop watering immediately and move the plant to a spot with better airflow. If the pot has no drainage, repot it into a container with holes using a well draining potting mix.
Poor drainage
PossibleHow to tell: Water sits on the surface of the soil for a long time after watering.
What to do: Mix in perlite or coarse sand to improve soil aeration. Ensure the pot is not sitting in a saucer full of standing water.

When to worry
If the stem base feels soft or mushy, the rot has likely spread too far to save the plant. Some minor wilting after a heavy rain is normal, but it should recover quickly.
Stopping it coming back
Only water when the top 2 inches of soil feel dry to the touch. Always use a pot with drainage holes to prevent water from pooling at the bottom.
