The RootMaker® Certified Grower's Program is open to commercial plant production nurseries or tree farms, whose primary business is providing top quality plant material to another nursery, landscape contractor, or the general public via retail garden centers. Cooperating nurseries and tree farms agree to follow best management practices available in other aspects of plant growth and health. RootMakerŪ Products Company will make available a list of best management practices for anyone seeking assistance.
