Vermicomposting is composting with worms. It is perfect for apartment dwellers, classrooms, anyone without a yard, or as an additional method of composting food waste. A special type of worm is used in vermicomposting, called Red Wrigglers. These are available by special order. In Manitoba, contact The Wriggler Wranch.

Red Wrigglers are especially useful for composting because of how much they eat. Each worm eats half its own weight in food and bedding each day. They will stay in their bin provided conditions are tolerable, as they hate light and vibrations.

Besides the worms, you will need a bin for them to live in and bedding material such as shredded paper. There needs to be holes in the top and bottom for air and drainage of excess moisture. Similar things can go into a vermicomposter as into a backyard composter. Generally, the worms are fed your organic material once a week. As the worms eat your garbage, they digest it and produce castings. These castings are the finished compost can also be used in the same way as humus from backyard composters.
