The definitive guide to vermicomposting is now fully updated, just in time for the 35th anniversary of its original printing. Detailed illustrations and accessible instructions show readers how to set up and maintain a small-scale worm composting system -- even in a small space like an apartment. After learning how to choose the right type of bin and selecting the correct worm species, readers learn how to care for and feed their worms, harvest the finished compost, and use it in their gardens or to create their own potting mix for container gardens and houseplants.
