  • Restore disturbed soils by tilling 2-3" of compost into upper 8" of soil
  • Loosen compacted subsoil, if needed, by ripping to 12" depth
  • Mulch landscape beds after planting
Existing Landscapes
  • Till in compost when re-landscaping
  • Mulch beds with organic mulches
  • Topdress turf with compost
