Oak leaves and pine needles will also decompose. However, shredded leaves will decompose more rapidly. Garbage can be used, if free of meat scraps. Meat scraps should not be used since they may attract dogs and raccoons. If garbage is used, be sure to cover it with one to two inches of soil after each addition to prevent odors and flies.
Less soil is needed if the garbage is cut finely and slightly packed.
Be careful when using large amounts of garbage in the compost pile. It can attract mice and rats. Cover the first layer of compost with one-half to one inch of top soil. Top soil is loaded with micro-organisms which will immediately begin to break down the organic matter. Top soil can be taken from your garden or purchased.
