Enrich Fine Bark Mulch is a premium grade bark product that provides a beautiful dark brown finish for flower beds, borders, or tree pits. It is manufactured from 100% natural bark, and is ideally suited as a protective layer over beds, borders, and pits. Enrich Fine Bark Mulch suppresses weed development, and helps reduce moisture loss. During manufacturing, Fine Bark Mulch material is milled to reduce particle size, and is subsequently graded to give a consistent particle size of 15mm.
