- Inspect the base of the stem for mushy tissue.
Likely causes
Poor Drainage
PossibleHow to tell: The soil stays soggy for days and the base of the stem looks mushy or discolored.
What to do: Stop watering immediately and allow the soil to dry out completely. If the plant is in a pot, ensure the drainage holes are not blocked.
Overwatering
PossibleHow to tell: The plant turns yellow and wilts despite the soil being constantly wet.
What to do: Adjust your schedule to water only every 10 to 14 days if the soil remains damp. If the plant is severely damaged, you may need to transplant it into fresh, fast draining soil.

When to worry
If the stem base is soft and mushy, the rot may be too advanced to save the plant. It is normal for the plant to die back naturally after it has finished its growing season.
Stopping it coming back
Only water when the top inch of soil feels dry and ensure your planting site has excellent drainage.
