Calculate how much mulch you need for your garden.
Volume = area (sq ft) × depth (ft); cubic yards = volume / 27.
A 200 sq ft bed covered 3 inches deep needs about 1.85 cubic yards of mulch.
A 2–3 inch layer is typical for weed suppression and moisture retention without smothering roots.
A standard 2 cu ft bag covers about 8 sq ft at 3 inches; divide the cubic feet by the bag size.
Yes. The same volume formula applies to any bulk material sold by the cubic yard.
