Backyard composting is best for yard and garden wastes like grass, leaves, and chipped wood. You can also put most food scraps in a backyard compost pile. There are many methods of backyard composting, including composting in heaps or in a container.

Worm composting is best for kitchen scraps like fruit and vegetable peelings. Red wiggler worms create vermicompost, a valuable fertilizer and soil builder. You can make a worm bin from inexpensive materials or purchase a pre-made worm bin kit. Worm composting can be done indoors.

We offer Adopt-a-Worm Classroom Composting Lessons for home, private and public schools.

 How to worm compost

There are many ways to worm compost. We recommend that beginners start by making a worm bin from a small plastic tote.

Supplies Needed:

  • Red Wiggler (Eisenia fetida) worms. Buy composting worms online (search "red wiggler worms Washington"), buy locally at Bay Hay & Feed (call ahead for availability) or 3-in-1 Worm Ranch or ask a local social media group if anyone has worms to share.

  • A plastic bin measuring approximately 2ft x 1.5ft x 9in. Drill holes in the bottom and sides for airflow.

  • A tray to put under the worm bin to catch vermicompost and drainage. Drainage should not occur and is a sign your bin is too wet.

  • Bedding. Shredded paper, brown leaves, or straw.  Do not use shiny paper, envelopes with plastic windows, or paper containing plastic.

  • Fruit and vegetable scraps. Use the Worm Feeding Guide.

Tips for Success:

  • Red wiggler worms eat approximately half their body weight daily.

  • Freeze your food scraps to prevent fruit flies and speed up composting.

  • Keep food scraps covered with bedding to prevent fruit flies and odor. 

  • Add fresh bedding and mix the bin contents regularly to allow air flow and to absorb excess moisture. Most problems that happen in worm bins come from too much moisture.

  • When your worm bin gets full of vermicompost, search online for harvesting methods.
