How Deep Should Mulch Be?
University of Minnesota Extension recommends a 2–4 inch mulch depth for balancing weed suppression and soil aeration, while keeping mulch clear of stems and trunks.
Read guide →Guide 02Mulch Bags per Cubic Yard
One cubic yard is 27 cubic feet, so it equals 13.5 two-cu-ft bags or 9 three-cu-ft bags; purchasing whole bags means 14 or 9 respectively.
