Worm Castings

Welcome to the Worm Castings Page!

Worm castings, also know as vermicast or vermicompost, is the waste excrement of earthworms. Worm castings make a great natural soil amendment and fertilizer. “Vermi” is a Latin word for worm, and is used an the words vermicast, vermicompost, and vermiproducts.

We have four wood heated 8x4ft bins that can hold in total 128,000 red worms and European night crawlers. Under perfect conditions the bins are calculated to be able to yield up to 11 tons of castings per year. That’s a lot of dirt to shovel!. We feed our worms a mix of manure from local farms, organic waste, and cardboard.

  1. I would like to prebuy some vermicompost for next spring.
    Please call me or e-mail me with cost of compost–I vermicompost myself, but I need more than I can produce for my home garden.
    I have a trailer that I can P/U bulk compost and bring it home that will work with a skip loader or bucket.
