Worm Composting Information

Overview

Worm composting or vermicomposting is a clean, safe method for disposing of kitchen and garden waste. It can be done indoors or out and provides a rich source of nutritious, inexpensive soil conditioner for houseplants, vegetables and ornamentals.

Worms

Specialized, surface dwelling worms are the most suitable for vermicomposting. Red worms and red wigglers can be used indoors; the earthworms you find in your driveway after a rainstorm cannot.

The Bin

Vermicomposting is most easily done in 10- or 20-gallon plastic storage bins. Drill 1/2-inch holes in the sides and bottom of the bin and place the bin on blocks. Commercially available worm bins are also available.

Bedding

Use shredded newspaper or cardboard, peat moss, hay or composted leaves for bedding. After harvesting the compost, replace the bedding.

Moisture

Bedding should have the moisture consistency of a damp sponge. When you squeeze the bedding, water should not wring out.

Temperature

Ideal vermicomposting temperatures range between 50 to 84 degrees Fahrenheit. Locate your indoor bin in the basement or place an outdoor bin in a shady location.

Food

Worms will eat fruit and vegetable scraps, garden debris, coffee grounds, eggshells and leaves. They will eat cereals and grains as well. Don't use too much citus--it can be too acidic. Do not compost meat or dairy products.
