About Blossom End Rot

Blossom end rot is a physiological disorder caused by calcium deficiency in developing fruit — not a disease. When fruits enlarge rapidly, insufficient calcium reaches the blossom end, causing the characteristic dark, sunken lesion. Regular calcium nitrate applications during fruit set and development prevent this condition and protect yield quality.
