A worm farm is a form of composting called vermicomposting. It allows you to put kitchen scraps to good use. The worms eat the kitchen scraps and turn them into a soil amendment that you can use in your vegetable and flower gardens. Any 5- to 30-gallon container, including an old freezer, will work to house your worm farm.
1 Remove the lid from the freezer, and set the freezer in a location that receives constant shade. The worms prefer the cover of darkness, and you don't want to move the freezer every time the sun comes out.
2 Shred some old newspapers, and place them at the bottom of your freezer. Wet the shredded newspaper so that it is moist, but not sopping wet.
3 Add any plant or grass clippings that you may have from weeding or mowing the lawn. You should have a total of 4 to 5 inches of newspaper and grass clippings in the freezer.
4 Top the grass clippings with a layer of soil. Make sure the soil doesn't contain any rocks or big lumps before placing it in the freezer.
5 Wet the soil and grass clippings with water from a garden hose. Again, you want the contents to be moist, but not drenched. Your worms will drown if too much water is in the freezer.
6 Add red worms to the freezer. The Louisiana Department of Environmental Quality recommends using red worms above all other worms.
7 Feed your worms vegetable scraps, fruit scraps, crushed up egg shells, tea bags, coffee grounds and hair. Do this every couple of days, and check the pile to make sure it is still moist. If it begins to dry out, add more water.
8 Wait three to six months before harvesting the compost. To harvest the compost push all of the compost to one side of the freezer. Add new bedding, soil and food to the other side of the freezer, and wait a few days for the worms to migrate to the new food. Remove the completed compost, and use it in your garden.
