How many bags of mulch do i need?

To determine how many bags of mulch you need, first calculate the area you want to cover by multiplying the length by the width (in feet) to get square footage. Then, decide on the depth of mulch you want, typically 2-3 inches. Most bags cover about 2 cubic feet; use this information to convert your total area and desired depth into cubic feet and divide by the coverage of each bag to find the total number of bags needed. Always round up to account for settling and any miscalculations.
