Likely causes
Overwatering
Most likelyHow to tell: The soil stays wet for more than 7 days and the stems feel mushy near the base.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant is in a pot, ensure it has drainage holes and empty the saucer after watering.
Phytophthora blight
PossibleHow to tell: You see dark, water soaked lesions on the stems and the plant wilts even when the soil is moist.
What to do: Remove and discard the infected plant immediately to stop the spread. Do not compost it, as the fungus persists in soil and debris.
