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.
