What you need:
  • Vermicomposter
  • Bedding (coco-fiber, Canadian sphagnum moss, shredded newspaper)
  • Newspaper
  • Red wiggler worms
  • Kitchen scraps
You've heard about composting with worms (known as vermiculture), but have you tried it? It's an effective way of composting kitchen scraps. Earthworm castings are considered the most beneficial of all soil amendments. Here's how to set up a tri-level worm composter called the "Can O' Worms." While it's only one of many ways to "vermicompost," the basic principles apply universally.

First prepare the bedding. The Can-o'-Worms composter comes with coco-fiber as bedding. You can also use sphagnum moss, sawdust, or shredded newspaper. Soak the bedding in warm water for 10-15 minutes, then squeeze out excess moisture.

Next, lay wet newspaper on the bottom level of the composter. This will keep the first layer of bedding from falling through the bottom grate.

Spread the bedding over the newspaper.

Add a layer of soil or compost on top of the bedding.

Add the worms to the bin. Worms are sensitive to light, so if you leave the top off of the bin for 15 minutes all the worms will burrow into the bedding. Special worms called "red wigglers" are required for vermicomposting. Regular earthworms will not work.

Once the worms have migrated into the bedding, add some kitchen scraps to the bin.

Cover the kitchen scraps with more damp newspaper, and the lower bin is ready. Place the second bin on top of the first. When the bottom bin fills up with worm castings, add more bedding and kitchen scraps to the second bin. The worms will move freely between the two, consuming whatever scraps you put in the second bin. Eventually the second bin will fill up, and you can start working on the third bin. By this time, most of the worms will be in the second bin, so you can empty the first bin and move it to the top.
