1. Carbon-rich “brown” materials, such as fall leaves, straw, dead flowers from your garden, and shredded newspaper.
2. Nitrogen-rich “green” materials, such as grass clippings, plant-based kitchen waste (vegetable peelings and fruit rinds, but no meat scraps), or barnyard animal manure (even though its color is usually brown, manure is full of nitrogen like the other “green” stuff). Do not use manure from carnivores, such as cats or dogs.
3. A shovelful or two of garden soil.
4. A site that’s at least 3 feet long by 3 feet wide.
