Worm composting is an incredibly efficient way to convert kitchen scraps, junk mail and paper scraps into nutrient-rich compost for your garden. Master gardeners agree that compost produced by worms will produce the best results and help your plants thrive! The Worm Factory's stackable, multi-tray design makes it the most efficient worm bin composter around. Worms begin eating waste in the lowest tray, and then migrate upward as food sources become exhausted in the lower levels. By allowing worms to migrate upward, the worms separate themselves from the finished compost that is ready for the garden.
