People usually raise red wiggler worms for fishing, to make garden compost or to start a worm farm. Whatever the reason, check garden supply catalogs, ads in gardening magazines and the Internet for your first supply of red wigglers. Since worms can't survive shipment in cold weather, order them before winter arrives.
Convert a plastic lidded container into a worm bin. Red wigglers need about 1 square foot of surface area per pound of waste material produced each week. Make 1/8- to 1/4-inch holes in the bottom for drainage and above the bedding for air. The number of holes needed depends on the size of the bin. A 10 gallon bin needs about 18 holes on all sides. A soldering iron, drill, heated ice pick or knitting needles are some of the tools you can use to make holes in soft plastic.
Place biodegradable bedding in the worm bin. Possible bedding materials include peat moss, aged manure, sawdust, dried grass clippings, hay, garden loam, shredded cardboard, newspaper, paper grocery bags and shredded leaves. Avoid highly acidic leaves, such as oak, since the worms don't like them. Also avoid colored or glossy paper that may have toxic dyes.
Soak paper bedding overnight to give the worms moisture for wiggling and burrowing around. For other bedding material, add enough water to make it slightly moist like a damp sponge. Fill the worm bin up to 6 inches deep with bedding. Check the bedding frequently to make sure it doesn't dry out. Use a spray bottle to keep it moist.
Protect the worm bin from sun and light. Red wigglers need a cool shaded place if raised outside. The ideal temperature for these worms is from 50 to 70 degrees Fahrenheit.
Feed the red wiggler worms a variety of fruit and vegetable scraps, leftover bread, pasta and grains every other day. To start out, feed 2 lbs. of worms 1 cup of scraps and adjust the amount up or down as needed. Avoid foods that can turn rancid such as peanut butter and animal and dairy products.
