Check these first
- Smell the soil for a musty or rotting odor.
- Check if the pot has drainage holes at the bottom.
- Gently lift the plant to see if the roots look firm and white.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow and the stems feel soft or mushy. If you smell a sour odor coming from the soil, the roots are likely decaying.
What to do: Stop watering immediately and let the soil dry out. If the damage is severe, remove the plant from the pot and trim away any black, slimy roots.
Poor Drainage
PossibleHow to tell: The soil stays wet for more than 10 days after watering. Water sitting in the bottom of the pot prevents oxygen from reaching the roots.
What to do: Repot the plant into a container with drainage holes using fresh, well draining soil. Ensure you empty any excess water from the saucer after every watering.

When to worry
If the stems are mushy and the plant is collapsing, it is a serious situation that requires immediate repotting. Minor yellowing can often be fixed by adjusting your watering habits.
Stopping it coming back
Always use a pot with drainage holes and wait for the top inch of soil to dry before watering again.
