Coffee grounds and tea bags also work well. Adding scraps twice a week works well, but rotate where you bury your garbage. Some people recoil at the idea of keeping worms in the house, under the sink, for example. The garage, away from extreme heat or cold, is a good alternative. The redworms will be most active at temperatures around 70 degrees, but they will survive at much higher or lower temperatures.
Harvesting is the process of separating the worms from the compost.
Under bright light, lay the contents of the bin on a large sheet of plastic. Then, separate the compost into small piles. The worms crawl to the bottom of the pile, leaving rich, earth-smelling humus on top. An excellent source for further information is Worms Eat My Garbage by Mary Appelhof.
