- Smell the soil for any signs of decay.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and wilt while the soil remains wet to the touch. 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 plant is in a pot, ensure it has drainage holes and empty the saucer after watering.
Poor Drainage
PossibleHow to tell: Water pools on the surface of the soil for a long time after you water. The roots look brown and mushy instead of firm and white.
What to do: Repot the plant into a container with better drainage holes. Use a well draining potting mix that includes perlite to help air reach the roots.

When to worry
If the stem base feels soft or mushy, the rot has likely spread too far. It is normal for the oldest bottom leaves to yellow occasionally as the plant grows.
Stopping it coming back
Only water when the top inch of soil feels dry to the touch. Always use a pot with drainage holes to prevent standing water.
