Check these first
- Smell the soil for a sour or rotten odor.
- Inspect the roots to see if they are firm and white or mushy and brown.
- Check if water is sitting in the saucer.
Likely causes
Overwatering
Most likelyHow to tell: The soil stays soggy and the plant base may look discolored or soft. You might notice a musty smell coming from the pot.
What to do: Stop watering immediately and let the top inch of soil dry out. If the damage is severe, repot the plant into fresh, well draining soil after trimming away any black or mushy roots.
Poor Drainage
Most likelyHow to tell: Water pools at the bottom of the pot or the soil remains saturated for days. The plant looks yellow and stunted.
What to do: Ensure your pot has drainage holes at the bottom. Use a potting mix that allows excess water to escape easily.

When to worry
It is serious if the roots are mostly black and mushy, as the plant may not recover. It is normal for the soil to be damp, but it should never be swampy.
Stopping it coming back
Always empty the saucer after watering and use a light, airy soil mix.
