Frequently asked questions

How much mulch do I need?

Multiply the bed area (sq ft) by the depth in feet (inches ÷ 12) to get cubic feet. Divide by 27 for cubic yards, or by the bag size (usually 2 or 3 cubic feet) for the number of bags. 100 sq ft at 3 inches = 25 cubic feet: 13 bags of 2 cu ft.

How many bags of mulch are in a yard?

13.5 bags of 2 cubic feet, or 9 bags of 3 cubic feet, make one cubic yard.

How much does a yard of mulch cover?

One cubic yard covers about 108 sq ft at 3 inches deep, 162 sq ft at 2 inches, or 324 sq ft at 1 inch.
