  • Why is there a hard core in my tomato?

    Created by Robert Rank on

    What causes my tomatoes to develop very many core extensions in the meat of the tomato and what can I do next year to avoid this problem?

    Hi Robert –

    Large white and tough cores inside tomatoes are most often related to the variety you are growing. However, in some cases dry weather conditions or too much fertilizer can contribute to the problem. Some articles I read suggest that older, juicy varieties may be more apt to develop hard, white central cores. I think simply switching tomato varieties next year will solve the problem.

    Hope it helps!



    OK. Thank you!
