The Yelm Earthworm & Castings Farm

Welcome to the Yelm Earthworm and Castings Farm. Please take a look around the farm to get a feel for our farm and it's history... Would you like to visit the farm?

The YELM Earthworm & Castings Farm is one of the largest worm farms in North America. We are dedicated to soil conservation, restoration and improvement.

YELM's Pumphouse - plenty of pure well water to nourish our 15 tons of redwoms.

The farm began operating in the mid-1980s as a mushroom farm. It was redeveloped as a worm farm in 1990 and was revitalized in 1997 through new management. We have excellent facilities, including more than 30,000 sq. ft. of enclosed production space and well water. The farm is full of charm, including our farm office housed in an old-time rail caboose.

We use time-tested, proven methods to grow large quanities of redworms (Eisenia fetida). The redworms are grown with solids-separated dairy manure and gathered using a two-step mechanical/hand sorting harvesting process. We are a full-time, full-service commercial redworm farm. We provide redworms for all types and sizes of projects for gardeners, home composters, farmers, institutions, and entreprenuers.

We employ a wide variety of machines to support our operation, including a forklift, loader, tractor, grinder, worm harvesters, shaker screen, irrigator, and other equipment.

Of course we have a garden at the Yelm Earthworm and castings farm where we test all of our products so that we know they will work and can better consult with you on their application.

Mmmmmmm... the fruits (or vegetables actually) of our labor - robust, flavorful spinach in this case.
