Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow or brown and the base of the plant feels mushy. The soil smells sour or swampy.
What to do: Stop watering immediately and let the top 2 inches of soil dry out completely. If in a container, ensure the pot has drainage holes and is not sitting in a saucer of water.
Poor Drainage
PossibleHow to tell: Water pools on the surface of the soil for a long time after rain or irrigation. The plant looks stunted and refuses to grow.
What to do: Amend the soil with grit or perlite to improve aeration if the soil is heavy clay. If the plant is in a pot, repot it into a well draining potting mix.

When to worry
Root rot is serious and can kill the plant if the roots turn black and mushy. It is normal for a few lower leaves to drop as the plant matures.
Stopping it coming back
Always allow the top inch of soil to dry out between waterings and ensure the planting site has excellent drainage.

Questions people ask
- Can I save a plant with root rot?
- If the rot is caught early, you can trim away the mushy roots and repot the plant in fresh, dry soil. If most of the root system is black and slimy, it is usually too late.
- How do I know if my soil drains well enough?
- Water should soak into the ground within a few minutes. If it sits on the surface for hours, your soil is likely too heavy and needs amendment.
