Likely causes
Overwatering
Most likelyHow to tell: The soil feels constantly soggy and the base of the stems looks dark or mushy.
What to do: Stop watering immediately and allow the top 2 inches of soil to dry out. If the plant is in a container, ensure it has drainage holes and empty the saucer after watering.
Poor Drainage
PossibleHow to tell: Water pools on the surface for a long time after you water the plant.
What to do: Amend the soil with perlite or coarse sand to improve aeration. If the plant is in the ground, consider transplanting it to a raised bed or a spot with better drainage.
