Unique in the landscape industry, Superhumus is processed from a blend of forest soil, fine bark, organic matter, sand and fine stone. These natural ingredients are washed off of logs in a wood yard water flume in Jay, Maine. Superhumus is screened (<7/8”) and has been used extensively since 1990 as a potting mix, park and trail mulch, slope stabilizer and as an amendment for heavy soils.
