Blossom-end rot on greenhouse tomatoes
This photo was submitted by a grower. Blossom-end rot is a due to lack of calcium in the fruit. The blossom end of the fruit develops brown to black, dry, sunken, leathery areas.
Prevent blossom-end rot by providing proper calcium level in the growing media, avoid uneven watering and avoid allowing plants to wilt. Plants also need healthy roots for calcium uptake.
