Check these first
- Feel the soil 2 inches down to check for sogginess.
- Inspect the base of the stem for soft or discolored tissue.
- Check that your pot has adequate drainage holes.
Likely causes
Overwatering
Most likelyHow to tell: The base of the stem feels soft or mushy and the leaves turn yellow quickly. You might notice a sour smell coming from the soil.
What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. If the plant is in a pot, ensure the drainage holes are clear and not blocked by debris.
Poor drainage
PossibleHow to tell: Water pools on the surface for a long time after you water. The soil feels heavy and dense like clay.
What to do: Amend the soil with coarse sand or perlite to improve airflow. If the plant is in a container, transplant it into a pot with better drainage holes.

When to worry
If the stem base is black or mushy, the plant is likely beyond saving. It is normal for the soil to stay damp for a day or two after a heavy rain.
Stopping it coming back
Always wait until the top 2 inches of soil are dry before watering again. Use a gritty, fast draining soil mix to prevent moisture buildup.
