Check these first
- Feel the soil to see if it is soggy.
- Check if the pot has drainage holes.
- Gently pull the plant out to inspect the roots.
Likely causes
Overwatering
Most likelyHow to tell: The soil feels soggy or swampy to the touch. The leaves may look limp and eventually turn brown or black.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the pot lacks drainage holes, move the plant to a container that allows excess water to escape.
Poor drainage
PossibleHow to tell: Water sits on the surface of the soil for a long time after watering. The roots will appear mushy and dark instead of firm and white.
What to do: Repot the plant into a well draining mix containing peat moss and perlite. Trim away any black or slimy roots before replanting.

Stopping it coming back
Only water when the top inch of soil is dry and ensure your potting mix is loose and airy.
