Backyard Composting & Worm Composting

What is composting?
Composting is a natural process of recycling organic materials. Backyard and worm composting speeds up this natural process. You are left with a dark, earthy-smelling soil amendment for building healthy soils, lawns, and gardens. Some people call compost “black gold.”

What is the difference between backyard and worm composting?
Backyard composting is great for yard and garden waste like grass, leaves, and chipped wood. You can put food scraps in a backyard compost pile, but some people worry about food attracting pests.

Worm composting removes that worry. Worm composting is a supplement to backyard composting and can be done on a small scale (even inside an apartment)! Worms eat kitchen scraps and create castings, which people think of as plant “health food.”
