Mulch Calculator

Formula: Volume (cu ft) = [Length (ft) × Width (ft) × Depth (inches)] / 12. Standard garden bed mulch depth is typically 3 inches. 1 cubic yard = 27 cubic feet.

⚠️ This calculator provides an estimate based on uniform bed dimensions. It is recommended to add a 5% to 10% extra buffer for uneven terrain, settling, and edging contours. Avoid piling mulch directly against plant stems or tree trunks to prevent moisture rot.
