Uses: Mulching beds, borders and gardens around trees and shrubs Coast of Maine Organic Products Dark Harbor Blend Enriching Mulch is an exceptionally rich, naturally dark, fine textured blend of self-composted barks. It helps retain moisture and insulate the surface soil against temperature variations that can harm roots.
