What Is a Red Wiggler? is a children's book introducing the use of red wiggler worms for composting food scraps and more. Megan shows how to set up a red wiggler worm bin and how to harvest the castings. Eric's photos and renderings of the inside of a worm show the importance of this very special worm. A journal is included for observations about the worms. The book is a current commentary on disposing of our food scraps, rather than them going to the landfill. The worm castings are the best soil enhancer a gardener can use, eliminating chemical fertilizer.
