It is also helpful to remove any perennial weed roots from the area beforehand, although their hold can be weakened by applying a light-excluding surface layer such as large sheets of cardboard or several thicknesses of spread out newspaper before adding the compost mulch. The newspaper or cardboard should be thoroughly wet to help it lie flat and keep it from blowing away until the overlying material is added.
