Grow Native! Professional Member Bohn’s Farm and Greenhouses is pleased to announce the transition is now complete for producing all of its landscape-ready herbaceous perennial crops with an environmentally friendly sphagnum peat-free growing media. Physical renewable ingredients of the new herbaceous perennial growing media, blended by St. Louis Composing of Valley Park, Missouri, also a Grow Native Professional Member and a Platinum Sponsor, include aged pine bark fines, Black Gold STA compost and aged rice hulls. Conversion to a sphagnum peat-free mix began in 2010 in preparation for the custom production of herbaceous perennials for the Novus International Headquarters landscape project, a Sustainable Sites (SITES) pilot project. Use of sustainable soil amendments, including the use of peat-free nursery growing media, is one of eight SITES “Sustainable Practices in Plant Production” criteria considered for the award of project rating points. Ultimately, the Novus International project received a prestigious three-star SITES rating. Prior to supplying plant material for the Novus International project, the Bohn’s Farm growing media contained 50% aged pine bark, 15% composted rice hulls and 35% peat.
