Create Your Own Compost Pile

GreenScapes Homeowners Secondary BannerYou can create a compost pile in your backyard or indoors, depending on your available space. Backyard and indoor composting are most suitable for households to convert small quantities of organic materials, such as yard trimmings and food scraps, into compost that can be spread in garden beds, under shrubs, or use it as potting soil for outdoor plants.

All composting requires three basic ingredients:

  • Browns—Includes materials such as dead leaves, branches , twigs
  • Greens—Includes materials such as grass clippings, vegetable waste, fruit scraps, and coffee grounds
  • Water

Having the right amount of greens, browns, and water is important for compost development. Ideally, your compost pile should have an equal amount of browns to greens and alternate layers of organic materials of different-size particles. The brown materials provide carbon for your compost and the green materials provide nitrogen, while the water provides moisture to help breakdown the organic matter.

There is no one "right" way to compost, but you may want to follow one of the approaches below:

Helpful Composting Tools

  • Pitchfork
  • Square-point shovel or machete
  • Water hose with a spray head
Backyard Composting Approach One1
  1. Select a dry, shady spot near a water destination for your compost pile or bin.
  2. Add your brown and green materials as you collect them, making sure larger pieces are chopped or shredded.
  3. Moisten dry materials as they are added.
  4. Once your compost pile is established, mix grass clippings and green waste into the pile and bury fruit and vegetable waste under 10 inches of compost material.
  5. Optional: Cover top of compost with a tarp to keep it moist.
  6. When the material at the bottom is dark and rich in color, your compost is ready to use (this is usually occurs in two months to two years).

Backyard Composting Approach Two1Image of man with compost bin
  1. Select a dry, shady spot near a water destination for your compost pile or bin.
  2. Before you add your brown and green materials, make sure larger pieces are chopped or shredded.
  3. Cover your composting area with a 6-inch layer of brown materials.
  4. Add a 3-inch layer of green materials and a little soil or finished compost.
  5. Lightly mix the two layers above.
  6. Top with a 3-inch layer of brown materials, adding water until moist.
  7. Turn your compost pile every week or two with a pitchfork to distribute air and moisture. Move the dry materials from the edges into the middle of the pile. Continue this practice until the pile does not re-heat much after turning.
  8. Your compost will be ready in one to four months, but let the pile sit for two weeks before using.
Indoor Composting

If you do not have space for an outdoor compost pile, you can compost materials indoors using a special type of bin, which you can buy or make yourself. Remember to tend your pile and keep track of what you throw in. A properly managed compost bin will not attract pests or rodents and will not smell bad. Your compost should be ready in 2 to 5 weeks.

Build Your Own Indoor Bin

  1. Drill 1/2-inch diameter holes in the bottom and sides of a plastic garbage can.
  2. Place a brick in the bottom of a larger garbage can, surround the brick with a layer of wood chips or soil, and place the smaller can inside on top of the brick.
  3. Wrap insulation around the outer can to keep the compost warm and cover the cans with a lid.
