Arizona Worm Farm


Worm castings are the richest natural fertilizer known to humans. That's right: as little as a tablespoon of pure worm castings provides enough organic plant nutrients to feed a 6" potted plant for more than two months. Worm castings stimulate plant growth more than any other natural product on the market. Unlike animal manure and artificial fertilizers it is absorbed easily and immediately by plants. But Worm Castings don't only stimulate plant growth: they also enhance the ability of your soil to retain water (because of its texture), and it even inhibits root diseases such as root rot..
