100% pure, raw, unprocessed worm castings. NOTE: MIgardener believes in compost being a living, breathing organism. For this reason, your worm castings may (probably) will come with worms, worm eggs, and other compost critters found naturally. We do not heat our castings, or allow them to dry out completely since living organisms need moisture to live! Food source: leaf compost (bedding material), 100% organic garden scraps, local coffee grounds, and free-range organic eggshells.
