For more than three decades, this best-selling guide to the practice of vermicomposting has taught people how to use worms to recycle food waste into nutrient-rich fertilizer for houseplants or gardens. Small-scale, self-contained worm bins can be kept indoors, in a basement, or even under the kitchen sink in an apartment - making vermicomposting a great option for city dwellers and anyone who doesn't want or can't have an outdoor compost pile. The fully revised 35th anniversary edition features the original's same friendly tone, with up-to-date information on the entire process, from building or purchasing a bin (readily available at garden supply stores) to maintaining the worms and harvesting the finished compost.
