The Benefits of Sheet Mulch

Sheet mulching, a layered mulch system, is a simple, effective technique for improving soil health, managing weeds without herbicides and increasing soil permeability.

Sheet mulching can be used either in establishing a landscape or to enrich existing plantings. In both cases, mulch is applied to bare soil or on top of cut or flattened weeds or turf. Trees, shrubs, herbaceous perennials and annuals are planted through the mulch, and small areas can be left open to accommodate established plants.

Sheet mulch can:

  • Suppress weed growth without chemicals
  • Reduce labor and maintenance costs—weeds are composted in place
  • Improve nutrient and water retention in the soil
  • Encourage favorable soil microbial activity and worms
  • Enhance soil structure
  • Improve plant vigor and health, often leading to improved resistance to pests and diseases
