    Hard to come by product in our neck of the woods at a decent price

    Love this product! So grateful that Concentrates carries this, since it’s out of stock in my area. We’re using it to fertilize California Oak trees, it’s high quality and absorbs into the soil very well.

    I like that the Oyster Shell flour comes in smaller bags that are easier to handle
