Worm composting, also called vermiculture, is nature's way of recycling. Rotting food, like fruits and vegetables, as well as shredded paper and cardboard, can be combined with organic soil and worms for worm composting. Composting with worms creates a nutrient rich humus that can be mixed into garden soil and used as a self-fertilizing topsoil.
Prepare your composting bin according to manufacturer's instructions, or just dig a hole. You may wish to line the hole with landscaping fabric to keep the compost separate from the garden soil.
Place a layer of damp newspaper or corrugated cardboard in your compost, followed by a layer of green waste, like food scraps and then a layer of organic gardening soil.
Continue layering until you've run out of green waste or you reach the top of your compost pile. The top layer should be soil, so as not to attract fruit flies or vermin and to keep foul odors from escaping.
Allow the compost to mature for two weeks, so that bacteria and microbes can grow, then add composting worms, like night crawlers or red wigglers. Spray the compost pile lightly before adding worms, then pour them right on top.
Stir the compost pile after a month or so, so that the outside of the pile is now on the inside, where it's warmer. Add a fresh layer of organic soil over the top again and let it continue to cure.
Sift the contents of the compost pile after another month or so, using a wire mesh screen. Allow the worm castings and smaller worms to fall through the mesh and into a bucket or wheelbarrow for distribution in your garden. The pieces that haven't been composted yet can be returned to the pile.
