Symptoms:
Blossom end rot is often misdiagnosed as a fruit disease. The blossom end of the fruit fails to develop normally, turning black-dark brown and eventually shriveling and becoming hard. Blossom end rot is usually due to a nutritional imbalance that is exaggerated by alternating periods of water stress.

Control:
Provide even soil moisture and follow recommended fertilization practices noting particularly the balance between nitrogen and calcium.
