We make our oyster shell flour by freshly grinding shells collected from our local fishmonger. It is a fantastic source of calcium that can sustain a plant without causing a nutrient lockout. This slow-release calcium improves soil tilth, helps soil maintain nutrients and boosts the plants' immune system.
