Worm waste, ejected in the form of castings, also called "vermicast" is one of the easiest ways to reuse your vegetable scraps from the kitchen and garden. Worm composting is so easy, it can be done almost anywhere. All you need is a container, or spot in the garden, bedding material, food scraps, and of course, worms.
Worms love to eat all kinds of food. They love food scraps, (but not meat, bones or dairy products because these may cause unpleasant odors or invite unwanted ‘guests’ into your worm bin). They also eat cardboard, and even material from vacuum cleaner bags. Then they turn it into nutrient-rich compost (castings). These castings can be used as a fertilizer for all types of plants. Worm castings are the richest form of natural fertilizer known to man. This will promote higher than average growth in plants.
The earthworm has been aptly called, "The Gardener's Unpaid Handyman." It tills the soil around root areas by its tireless burrowing. The burrows form channels through which root growth may reach down into the subsoil for minerals and moisture. They also absorb rainfall quickly for storage in the soil instead of allowing it to run off, carrying away valuable top soil. Most important of all, the earthworm eats, digests and enriches dead and decaying vegetable wastes in the soil, ejecting it in the form of casts, rich in plant food value, watersoluble, immediately available to plant roots.
One of our favorite, and least messy ways to compost includes the "SWAG", please check out the page on the "SWAG", but you can also raise worms in bins, wood, metal or plastic, in bathtubs, or just in a favorite spot in the yard. Worms also grow well under rabbit hutches. (There are books on just this subject available through workingworms, and we have used this method with much success.) Worms will stay in one place ...will not crawl out or migrate if food and moisture are adequate.
