Check these first
- Smell the soil for a musty or rotting odor.
- Check if the pot has drainage holes.
- Inspect the roots for a dark, slimy appearance.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and the base of the stem feels mushy or soft. You might notice a sour smell coming from the soil.
What to do: Stop watering immediately and let the soil dry out. If the damage is severe, remove the plant from the pot, trim away black mushy roots, and repot in fresh, well-draining soil.
Poor Drainage
Most likelyHow to tell: Water pools on the surface of the soil for a long time after watering. The pot may lack holes or the soil is too dense and heavy.
What to do: Ensure your pot has drainage holes at the bottom. Mix perlite or coarse sand into your potting soil to improve aeration and drainage.

When to worry
If the stem base is soft and mushy, the rot may have spread too far to save the plant. It is normal for a few roots to die back during repotting, but widespread decay is serious.
Stopping it coming back
Always check the top inch of soil before watering and never let the pot sit in a saucer of standing water.
