Likely causes
Overwatering
Most likelyHow to tell: The soil feels constantly wet or swampy, and the base of the stem may feel soft or mushy.
What to do: Stop watering immediately and let the soil dry out completely. If the rot is severe, remove the plant from the pot, trim away black or slimy roots, and repot it in fresh, well draining soil.
Poor Drainage
PossibleHow to tell: Water pools at the bottom of the pot or the soil stays wet for more than two weeks.
What to do: Ensure your pot has drainage holes at the bottom. If it does not, move the plant to a container that allows excess water to escape.

When to worry
If the stem base is soft or the plant is leaning significantly, the rot may have reached the core, which is often fatal. Some root loss is normal when repotting, but mushy roots are a sign of trouble.
Stopping it coming back
Always wait until the top half of the soil is dry before adding more water. Use a potting mix specifically designed for indoor plants that includes perlite for better airflow.
