Chipping is your best method of reducing large, awkward branches to a fraction of their size, making handling easy and creating a useful ground cover that helps control weeds and retain moisture in hot weather. Leaf and twig cleanup is also simple with the Stiler Chipper / Shredder, creating a fine mulch that adds that special finishing touch to your perfectly manicured flowerbeds. Chips and mulch increase the rate of decomposition, adding nitrogen into the soil for improved plant growth. Groundcover reduces evaporation of valuable moisture by blocking direct sunlight to the surface of the soil.
