It works and it is organic
Love this for adding calcium to my tomatoes, and all of my medicinal herbs! My tomatoes don’t get blossom end rot when I use this at planting, and I feel better knowing it is an organic supplement, so I’m not feeding bad chemicals to my family by using this! Made with 100% ground oyster shell, so it is Definitely good stuff!
