How to Make a Vermicomposting Bin


Vermicomposting is a simple way to not only dispose of biodegradable kitchen waste, but to create an excellent amendment for your garden's soil. All you need some redworms, some opaque plastic storage bins, and a drill. Add shredded newspaper, grass and leaf clippings, soil, kitchen scraps, worms, and water. Cover them and keep feeding them and your worms will keep making delightful vermicompost for your garden. Best of all, your vermicomposting bin isn't difficult to put together and will be reusable for as long as you like.

Step 1

Poke holes all over the bottoms of two of the three storage bins. On the third, only poke holes along the upper 2/3 of the sides. Do not poke any holes in the bottom of the third. Use the drill for all hole-poking, and keep the holes at least an inch apart.

Step 2

Put the bin with the solid bottom on the bottom. Stack one of the other storage containers on top of it. Put a layer of slightly damp (not soggy) shredded newspaper and soil in the bottom.

Step 3

Bury kitchen scraps in the newspaper and soil bed. Add the worms. Cover the worms and their bed with a piece of damp cardboard. This will protect your vermicompost from pests and your worms from direct sunlight.

Step 4

Add kitchen scraps as you have them, and water the bedding lightly whenever it seems to be getting dry.

Step 5

Lure the worms from the finished vermicompost to the third bin when you want to move it into your garden. Stack that bin on top of the bin full of vermicompost. Fill it with damp newspaper, leaf clippings, or grass clippings mixed with soil. Add kitchen scraps and damp cardboard. Within a couple of weeks, the worms will find their way from the bottom bin into the top bin as they forage for food. It's now safe to move the compost from the bottom bin into your garden.

Tips and Warnings

  • Vermicomposting bins do not have any unpleasant odors when they are properly maintained. For this reason, make sure they are lightly moist, but never soaking. The bottom storage bin that does not have holes in it will catch excess water, but flooding should be avoided. Do not compost meat products, dairy products, pet waste, or human waste in your vermicomposting bins. Worms do not like these things, and they will sit and rot rather than being nicely composted. Do not try to attract earthworms from your garden to live in your compost bin. Earthworms do not do well in enclosed spaces, while redworms are quite happy to live there. Redworms are available from garden suppliers, as well as some pet and bait shops.
