Controlling Garden Pests Naturally and Organically

Blossom End Rot

Blossom end rot on fruits such as tomatoes occurs because the plant is deficient in calcium. It also attacks peppers, watermelon, squash, eggplant and sometimes cucumbers.

It starts out as a small watery looking spot that turns brown and begins widening as the fruit ripens. The tissues then look dry and leathery. Calcium deficiency can be lessened with the application of lime or gypsum.

    I wanted to ask a question. I do have a problem with the tomatoe plants and the blossom end rot. Can I add the lime or gypsum now over the existing soil without harming the plants? Please let me know. Thank you very much.

    I have golden summer squash that is turning brown in the middle of the squash. Leaves look great and so far no signs of bugs. Why is my squash seemingly rotting in the middle?
