Worm composting or vermicomposting is the practice of using worms to make compost. The word vermi is the Latin word for worm, and worms like to feed on slowly decomposing organic materials (e.g., vegetable scraps). The end product, called castings, is full of beneficial microbes and nutrients, and makes a great plant fertilizer.
