A cubic yard of mulch weighs 400 to 800 pounds, with a higher moisture content making the material heavier. Each unit is 3 feet tall, 3 feet long and 3 feet wide.
Most full-size pickups can hold up to 3 cubic yards of mulch. Each yard of mulch covers 324 square feet at 1 inch deep, 162 square feet at 2 inches deep, 108 square feet at 3 inches deep or 81 square feet at 4 inches deep.
Mulch prevents weed growth, reduces moisture evaporation, moderates soil temperatures, inhibits disease and improves fertility. It can also make maintenance easier and improve the appearance of the landscape.
