Located on a wildflower prairie between Puget Sound and Mt. Rainier, the center of our soil products business is located in our on-farm Yelm Soil Building Depot. The depot is a large, comfortable room to display and sell products. The depot is THE place to order or pick-up earthworm castings and compost and our deluxe earthworm potting soil. It’s also the spot to find a huge selection of organic soil amendments and gardening supplies.

The Yelm Soil Building Depot’s beautiful, new public demonstration garden shows the best, most successful organic gardening methods. Developed in conjunction with the Yelm Earthworm & Castings Farm, the demonstration garden uses square-foot garden techniques, as well as rock powders and earthworm soil products, for maximum productivity.

The Yelm Soil Building Depot is the spot in western Washington to begin building living soils that will excel at growing high-quality food and plants. Visiting the Yelm Earthworm and Castings Farm...
