Pocket Botanist
Check these first
- Smell the soil for a musty or rotten odor.
- Check if the pot has drainage holes.
- Gently lift the plant to see if the roots are mushy or firm.
Likely causes
Overwatering
PossibleHow to tell: The leaves turn yellow or mushy and the soil smells sour or swampy. The roots will look dark, slimy, and soft instead of firm and white.
What to do: Stop watering immediately and remove the plant from its pot to inspect the roots. Trim away any mushy, black roots with sterile scissors and repot in fresh, well draining soil.
Poor Drainage
PossibleHow to tell: Water sits on the surface of the soil for a long time after watering. The pot may lack drainage holes, trapping excess moisture at the bottom.
What to do: Ensure your pot has drainage holes at the bottom. If it does not, repot the plant into a container that allows excess water to escape freely.

When to worry
Root rot is a serious condition that can kill the plant quickly if left untreated. If the entire root system is black and mushy, it is likely too late to save.
Stopping it coming back
Always use a well draining potting mix and never let your plant sit in a saucer full of standing water.
