Blossom-end Rot is a disease aggravated by widely fluctuating soil moisture, high temperatures, too much nitrogen fertilizer, and a deficiency of calcium in the soil.

Have your soil tested and adjust the soil to a pH of 6.5 to 7.0. Don't over-fertilize, don't plant tomatoes where drainage is poor, mulch the plants with organic matter to help retain moisture, and try to ensure uniform soil moisture by watering deeply once every 7 to 10 days, making sure water penetrates at least 12 inches deep into the soil.
