What makes tomatoes rot on the bottom?

If you see a dark, rotting spot on the bottom of your tomatoes, it's blossom-end rot. This problem, caused by a calcium deficiency, can be solved a few ways. When tomatoes, peppers, melons, and eggplant develop a sunken, rotten spot on the end of the fruit, the cause came long before you found the problem.

Similarly, how do I fix blossom end rot on my tomatoes?

Prevention and Control
  1. Maintain consistent levels of moisture in the soil throughout the growing season.
  2. Prevent calcium deficiency with Tomato Rot Stop.
  3. In cold climates, allow soil to warm before planting; cold soils limit nutrient uptake.
  4. Maintain soil pH at or near 6.5.
