South Mill Mushroom Farms

Our mushroom farming story begins almost 90 years ago, in 1932, when Louie Pia began operating a small mushroom farm in southeastern Chester County, Pennsylvania. In the 1950s, the Pia family began supplying mushroom growing substrate to many local, family-owned mushroom farms and in a few short years, grew to become the area’s largest fresh mushroom supplier.

In 1982 the family purchased one of Pennsylvania’s largest mushroom farms and soon were selling fresh mushrooms directly to the retail, wholesale, food service, and commercial markets under the “South Mill” name.

Providing North America with Responsibly Grown Fresh Mushrooms

In the past decade, we have continued to grow the South Mill company to new heights with a variety of value-add mushroom products, aggressive expansions, and the acquisition of state-of-the-art mushroom farms across North America. Through this, we are able to fulfill our mission of nourishing the planet by providing the North American market with responsibly grown, great tasting,
good-for-you mushrooms.

Authenticity Reflected in Every Mushroom

Authenticity is more than a guiding principle for everything we do at South Mill. It’s how we grow the best mushrooms, from start to finish. We farm the straw used in our substrate, harvest our mushrooms with attention and care, and deliver them to retailers and restaurants across North America, ready for your plate.
