Likely causes
Poor Drainage
Most likelyHow to tell: The soil stays wet for more than 10 days, and the leaves start to yellow or wilt despite the wet soil.
What to do: Repot the plant into a container with large drainage holes using a well draining potting mix. Add perlite to the soil to improve aeration.
Overwatering
PossibleHow to tell: The base of the stem feels soft or mushy, and the plant looks generally unhappy.
What to do: Allow the top inch of soil to dry out completely before watering again. Stick your finger into the soil to verify dryness before adding more water.

When to worry
If the stem base is mushy and the roots are black and slimy, the plant is likely too far gone to save. If only a few roots are affected, you can trim them and repot in fresh soil.
Stopping it coming back
Always let the top inch of soil dry out between waterings and use a pot with excellent drainage.

- How often should I water to avoid rot?
- Water every 5 to 10 days, but only after checking that the top inch of soil is dry. Never let the plant sit in a saucer of standing water.
