Landscape Mulch Calculator

Multi-Bed Batch Calculation

A full landscape is the sum of its beds. Measure each bed, calculate its cubic yards with the formula Length x Width x Depth in inches / 324, then add the totals. A front border of 200 sq ft, a side bed of 150 sq ft, and tree rings of 100 sq ft total 450 sq ft. At 3 inches deep that is 4.17 cubic yards. Enter the combined area above to skip the per-bed math. The calculator adds a 10 percent buffer for settling, which matches how landscape suppliers price bulk orders by the cubic yard.

Total Yards for the Whole Yard

Most residential landscapes use 3 to 6 cubic yards of mulch per year. A large property with deep borders and many tree rings uses 10 to 20 cubic yards. The table shows total yards by combined bed area at 3 inches deep. Order one full dump truck load of 7 to 10 cubic yards for projects in that range to cut delivery trips.

Material Selection Guide

Choose one mulch material for the whole landscape to keep a consistent look. Shredded hardwood is the best all-around pick. It looks uniform, knits together to block weeds, and feeds the soil as it breaks down. Bark nuggets last 2 to 4 years and resist matting in shrub borders. Dyed black or brown mulch holds color for a finished look on front yards. The Professional Grounds Management Society (PGMS) uses shredded hardwood as the commercial landscape standard. Bulk delivery saves 30 to 50 percent over bags for any landscape above 3 cubic yards.

How do landscapers estimate mulch fast?

Landscapers estimate mulch by breaking the yard into simple shapes. They measure each bed as a rectangle, circle, or triangle, calculate the square footage, and add the totals. Then they divide by the coverage figure for the chosen depth. A 2 inch depth covers 162 sq ft per yard, and a 3 inch depth covers 108 sq ft per yard. This method gets within 10 percent of the true total for most yards.

How often should a landscape be re-mulched?

A landscape needs fresh mulch once a year, usually in spring. Top-dress with 1 inch to restore color and depth rather than a full replacement. Shredded hardwood breaks down in 1 to 2 years and needs the annual refresh. Bark nuggets last longer and can skip a year. Rake the old mulch loose before adding the new layer.

How to Plan a Whole-Yard Mulch Order

Planning a full landscape order takes four steps. Walk the yard and list every bed, border, and tree ring. Measure each one as a rectangle, circle, or triangle and record the square footage. Add the areas together and divide by the coverage figure for your depth. Add 10 percent for settling, then round up to the nearest half cubic yard. A yard with 1,000 sq ft of beds at 3 inches needs about 10 cubic yards delivered.

Bulk delivery beats bags for the whole yard. One dump truck carries 7 to 10 cubic yards and saves 30 to 50 percent over the bagged cost. Schedule the drop for a dry morning and tarp the driveway under the pile. Spread the mulch within a week before it mats or sours. Plan one hour of labor per cubic yard, so a 10 yard order is a full weekend for one person or a single day with two helpers and a wheelbarrow.
