Frequently asked questions
How many bags of mulch are in a cubic yard?
One cubic yard contains 27 cubic feet. It takes 13.5 bags of 2-cubic-foot mulch (purchase 14 bags) or 18 bags of 1.5-cubic-foot soil to equal one cubic yard.
How deep should mulch be in a garden bed?
A 3-inch layer is optimal for weed prevention and retaining soil moisture. Less than 2 inches allows weeds to sprout, while more than 4 inches can starve shallow plant roots of oxygen.
