There is no better or more impactful enhancement to a landscape than rebarkdusting. Mulch breaks down and becomes less effective with age, causing many problems. Lack of mulch reduces weed control and increases moss build-up as well as increasing evaporative water loss during the summer. In addition, rebarkdusting is the simplest way to make your property look fresher and brighter. We recommend rebarkdusting every other year at the end of winter or early spring.
