Mulch Calculators

Mulching Calculators

• Mulch to Cover Area: Enter an area size (e.g. 45 square feet or 0.75 acres) and depth of mulch wanted, and see estimated amount of mulch needed. Use the Size of Land Calculator if your area is unknown.
• Mulch to Cover Circular Area:  Enter the diameter (D) of the circle and depth of mulch wanted, and see estimated amount of mulch needed.
• Mulch to Cover Rectangular Area: Enter the length (L) and width (W) of the area and depth of mulch wanted, and see estimated amount of mulch needed.
• Mulch to Cover Four Sided (not squared) Area: Enter the length of the four sides (a,b,c,d) and the diagonal (D) of an irregular area (see diagram) and the depth of mulch wanted, and see estimated amount of mulch needed.
• Mulch Cost Estimate: Enter the amount of mulch needed, choose a type of mulch and it will provide an estimate of the cost.
• Mulching With Straw (Irregular Area): Enter the length (L) and width (W) of the rectangular area and it will estimate the number of bales of straw needed to mulch the area with straw.
• Mulching With Straw (Area): Enter the area (acres, square feet) to see an estimate of the number of bales of straw needed to mulch the area with straw.
• Bulk vs Bag Price Comparison: Enter the bulk mulch and bag prices and volumes, and it tells you which is cheaper and by how much.
• Bulk Mulch Coverage: Estimates the area that can be covered by a volume (e.g., garden center scoop) of bulk mulch based on the number of units (bulk scoops), size of units (cubic yards) and the depth the mulch will be spread.

If mulch is not the best application, consider using Landscape Fabric and the Landscape Fabric Calculator.
