Composting Recipe

Size:   You compost pile should be between 3' x 3' x 3' and 5' x 5' x 5'. We suggest a "bin" to contain your compost pile.


Surface Area:   "Greens" and "browns" should be chopped into 1" to 2" pieces. Small pieces will increase the surface area of your pile and stimulate airflow.


Composition:   Alternate 3"-6" layers of "greens" and "browns" to start. You are seeking a mix of 25-30 parts carbon to 1 part nitrogen in your pile. Mix the "green" and "brown" layers as you build them. Avoid meats, fats, dairy products, bones, feces, crab grass, weeds with mature seeds, diseased plants and plants treated with chemicals. See a list of "greens" and "browns" below.


Water:   Add enough water to your pile so it is the consistency of a wrung-out sponge. A pile that is too wet will smell bad. A pile that is too dry will take longer to decompose.


Air:   Turn the soil where the pile is to be placed to stimulate airflow. You can also build the pile on-top of branches, wire mesh or an old wooden pallet. Turn your pile when the internal temperature reaches 131° to 140°F. In warm weather turn your pile weekly. Finished compost will no longer heat above 110° and will have shrunk to 1/2 its original volume.


Greens:   Fruit rinds, bananas and peels, beans, beet tops, berries, broccoli, carrots and tops, celery, coffee grounds, pet hair, garden waste, overgrown vegetables, grass clippings (no pesticides), moldy food (no meat, fat, cheese or bones), onions and skins, green leaves, spent hops, human hair, lettuce, manure from herbivores only, melons, pond algae, potatoes and peels, pumpkins, squash, recycled water from cleaned-out fish tanks, weeds without mature seeds.


Browns:   Paper, shredded eggshells, end-of-season annual plants, straw, saw dust (small amounts), cotton string, oats, cabbage and broccoli stalks, grain hulls, tissue and cardboard cores, wool, autumn leaves, dryer lint, lawn thatch, turnips, peanut husks, stalks from perennial plants, chipped branches, vacuum cleaner sweepings, coffee filters, corn cobs, corn stalks, cotton, landscape trimmings, paper towels.
