Pocket Botanist
Check these first
- Smell the soil for a foul or rotten odor.
- Check if the pot has functional drainage holes.
- Inspect the roots for a dark, mushy appearance.
Likely causes
Overwatering
Most likelyHow to tell: The base of the plant feels mushy and the soil smells sour or swampy. You will notice the foliage turning brown or black at the base.
What to do: Stop watering immediately and let the top inch of soil dry out. If the plant is in a container, ensure it has drainage holes and repot into fresh, well draining soil if the roots are dark and slimy.
Poor Drainage
PossibleHow to tell: Water pools on the surface for a long time after you water. The soil stays heavy and wet for more than 4 days.
What to do: Mix perlite or coarse sand into your potting mix to improve aeration. Always empty the saucer under the pot 15 minutes after watering so the plant never sits in standing water.

When to worry
If the entire plant is mushy and collapsing, it is likely too late to save. Minor root damage can be fixed if you catch it early.
Stopping it coming back
Only water when the surface feels slightly dry to the touch, and never let the plant sit in a tray of water.
