Oyster shell is a key ingredient for strong eggshells. Our oyster shell grit gives laying hens a clean, natural way to self-regulate calcium. The result is consistently stronger eggshells and fewer day-to-day quality swings.
In addition, for garden soils, oyster shell grit breaks down slowly, gently buffering acidity and feeding perennials, shrubs, and trees over time. Oyster Shell Grit is the priority when soils benefit from a slow-release calcium profile rather than a quick pH bump
Ideal for bocce court surfacing, the oyster flour compacts smoothly for a fast, even playing surface that’s easy to level and refresh through the season. It also brightens the court for better sightlines while staying comfortable underfoot.
In addition, for garden soils, oyster flour improves calcium availability, helping counter low pH and supports plant growth—especially in new beds and edibles. Oyster Flour is the priority when soils need a quicker-release calcium and gentle pH lift.
