- Inspect the drainage holes to ensure they are not blocked.
- Lift the pot to see if it feels unusually heavy.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow or brown and the stems feel soft near the soil line. You might also notice a sour smell coming from the pot.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the soil remains muddy, repot the plant into fresh, well draining potting mix and trim away any black, mushy roots.
Poor Drainage
PossibleHow to tell: Water sits on the surface for a long time after you pour it. The pot might lack holes or the soil has become too compacted over time.
What to do: Ensure your pot has at least one large drainage hole at the bottom. Mix in perlite or coarse sand to your potting soil to improve airflow and drainage.

When to worry
If the stems are turning black and mushy, the rot has likely spread to the crown and the plant may not recover. It is normal for a few older leaves to yellow occasionally, but widespread wilting is a sign of trouble.
Stopping it coming back
Always use a pot with drainage holes and wait until the top inch of soil is dry before watering again.
