How to Get Rid of Blossom-End Rot Naturally

Blossom-end rot, a condition that affects tomatoes, squash, peppers and watermelons, is caused by a calcium deficiency and can be identified by circular, brown leathery spots on the bottom of fruit. Low soil pH and improper watering are two common reasons a plant is calcium deficient. It tends to be the biggest problem for the first fruits of the season but can occur throughout the growing season. Once a tomato or other vegetable has blossom-end rot, you can't get rid of it. Fortunately, you can prevent the condition from occurring on non-contaminated fruits.
