What materials are used in SBS composts and soil mixes?
Depending upon the specific soil product selected, the following various organic materials may be included: landscape and tree trimmings, vegetative materials, cotton burrs, dairy compost, and in the case of soil mixes, various types of soils and sands. SBS does not use treated lumber, pine bark, pallets, mushroom compost or raw manure in any of their products, as these items have been found, through extensive testing, to be detrimental to routine landscape plants and/or to the environment.
