Every gardener can tell when earthworms have “worked” their soil. The soil is more pliable and everything grows so much better. Why is this the case?  Earthworm castings are full of nutrients and microbes which are beneficial for a healthy soil and garden. I talk with Luke Arthur -- founder and CEO of Simple Grow, an organic producer of earthworm castings -- about how beneficial earthworm castings are, what exactly is in them, why it is a safer way of fertilizing and how even your houseplants will benefit.
