Oyster Shell Flour

Oyster shell flour is added to worm bins as a mineral supplement, providing various benefits. It helps balance the pH level, creating an ideal slightly alkaline environment for worms. Rich in calcium, it supports their overall health. The gritty texture aids digestion, as worms have gizzards to break down food efficiently. Furthermore, oyster shell flour enhances the quality of worm castings, resulting in nutrient-rich vermicompost for plants. Caution must be taken not to overuse it, as excessive calcium can disrupt the bin's balance. A small amount occasionally ensures the worms thrive in a favorable environment.
