This can happen at any time as the tomatoes mature, and most often on the first tomatoes of the season.
What causes tomato rot?
The culprit of blossom end rot in tomatoes is not a bug or a disease. This tomato problem, also known as bottom rot, is caused by a lack of calcium brought on by dry conditions. Tomato plants need calcium in all actively growing parts, from the roots to the fruits. Calcium is transported from place to place by water.
How do you prevent tomato rot?
You can’t save fruit that already has it, but you can help future fruit avoid it. Consistent watering, especially during fruiting, is the best way to prevent end rot. Besides that, ensuring your plants have healthy, balanced soil will give you the best chance for an abundant harvest.

What disease do tomatoes get?
