  • Black bottoms on tomatoes

    Created by Carol Kane on June 29, 2015 at 4:23 pm

    Some of my tomatoes get a flat black area on the bottom. Is it a watering problem or what? Please help.

    Carol –

    It sounds like you’re seeing blossom end rot.

    If your ripening fruit develop a dark spot at the lower end, a spot that gradually widens and deepens, you’re looking at blossom-end rot. It’s an environmental problem most often caused by uneven watering or by calcium deficiency. (These can be related; uneven watering can interfere with the uptake of calcium.) The simplest treatment is therefore pre-treatment: make sure soil is rich in all necessary nutrients (including calcium), and water regularly. Mulches also help maintain even moisture levels.
