Check these first
- Smell the soil for a musty or rotten odor.
- Check if the pot has drainage holes.
- Feel the soil 2 inches deep to see if it is soggy.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow or mushy, and the soil smells sour or swampy. You might see the base of the stems starting to turn dark and soft.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant is in a pot without holes, move it to a container with drainage. Trim away any black, slimy roots and repot in fresh, well draining soil.
Poor Drainage
Most likelyHow to tell: Water sits on the surface of the soil for a long time after watering. The plant looks wilted despite the soil feeling heavy and wet.
What to do: Ensure your pot has adequate drainage holes at the bottom. Mix perlite or coarse sand into your potting mix to improve airflow around the roots. Never leave the pot sitting in a saucer of standing water.

When to worry
If the stems are black and mushy at the base, the rot may be too advanced to save the plant. It is normal for older foliage to fade as the plant enters dormancy.
Stopping it coming back
Water only when the top inch of soil feels dry to the touch. Use a light, airy soil mix that does not hold onto excess moisture.
