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.

 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 ( call 360 598 4242) 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 this worm feeding guide for reference (external source).

Set Up:

 

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. 

    • Mix dry, shredded paper into the compost to ensure air flow throughout the bin 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.
