Our Favourite book on the subject of Vermicomposting is "Worms Eat my Garbage" by Mary Appelhof . While there are many other books on the subject, this one remains the easiest and most complete we have found. We usually have this book in stock if you would like to get a copy from us.
We also sell a book called "Compost by Gosh!" by Michelle Eva Portman. It is a fun guide to worm composting for kids.
