Founded in 2019 by Ross Devereaux and his family, Arbor Spring Farms began with a vision to bring premium, locally grown functional mushrooms to life—right in the heart of Michigan. What started as a passion project in a repurposed office building quickly grew into a mission-driven farm and production company that values traceability, freshness, and purity above all.
From day one, Ross set out to know exactly where every element of the process came from. It all starts with our substrate—the nutrient-rich growing medium, typically a blend of hardwood sawdust and organic materials, that serves as the foundation for mushroom cultivation. This is where the mycelium, the root-like network of the mushroom, first takes hold and grows strong. Once inoculated, this substrate becomes what’s called spawn, the living, thriving system that ultimately produces the beautiful fruiting bodies you see on our farm.
