How do I start a backyard compost pile?

You can buy a backyard bin from your local hardware store or create your own. Zero Waste Marin also sells them at a discount during our composting courses. Here are some tips to get started on backyard composting:

  • Transfer the organic waste from your kitchen compost pail to your backyard compost pile as often as needed.
  • Avoid adding pesticide- and herbicide-treated grass clippings, leaves, twigs, straw, acorns, moss and algae.
  • Do not fill your backyard compost pile with meat scraps, fish bones, bacon fat, cleaning chemicals, pet waste or diseased plants, all of which are capable of attracting pests and spreading disease.
  • To speed up the composting cycle, place your compost bin in an area that will receive sunlight. Use a compost turner, pitchfork or shovel to aerate your pile every two weeks by mixing up the contents (as if you were tossing a salad).
  • A great compost has a balance of carbon, nitrogen, air and water.
