Rocky Mountain Compost has been providing high quality, nutrient rich, soils to Yellowstone County residents and businesses for over 20 years. Used to amend gardens, prep yards for sod or seed, refurbish athletic fields and maintain healthy golf course greens, our variety of products give you the greatest opportunity to have vibrant, healthy plants every season!

Committed to producing premium products, we create our soils, decorative wood mulch and ag products on-site from locally sourced, natural materials. We encourage residents and businesses alike to bring your grass clippings and livestock manure to us for free! We also accept wood materials for a small fee.

Since our establishment, Rocky Mountain Compost has expanded our product line to include erosion control filter sock, rental equipment for the DIY’er, livestock, bedding, dust-control arena footing, and solutions for alkaline or clay soils. Many of our products can be purchased bulk at our Billings production site. Our soil products packaged in our largest, 1 cubic yard, “Big White Sacks are Best!” bags down to our smallest, 1 cubic foot bags, are carried by our retail partners throughout Montana and the surrounding states.
