Check these first
- Feel the soil an inch down to see if it is soggy.
- Check that the pot has working drainage holes.
- Smell the soil for a sour or rotten odor.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow or brown and the plant wilts even though the soil is wet. The roots will look mushy and dark instead of firm and white.
What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. If the soil is heavy, repot the plant into a well draining mix with plenty of perlite.
Poor Drainage
Most likelyHow to tell: Water pools on the surface of the soil or the pot does not have enough holes. The plant stays constantly saturated, leading to root suffocation.
What to do: Ensure your pot has large drainage holes at the bottom. Elevate the pot on bricks or feet to allow excess water to escape freely.

When to worry
If the stems feel soft or mushy near the base, the rot has likely moved into the crown and the plant may be beyond saving. Wilting that does not improve after a day of drying out is a major red flag.
Stopping it coming back
Only water when the top inch of soil is dry and never let the pot sit in a saucer of standing water.
