Mulch, Topsoil & Gravel Calculator
Calculate mulch cubic yardage, total square footage, 2 cu ft / 3 cu ft retail bag counts, and bulk delivery weights for flowerbeds and garden paths.

Calculating Landscape Bed Coverage
Mulch suppresses weed seed germination, moderates root temperature fluctuations, and slows soil moisture evaporation. Applying mulch too thin (less than 2 inches) fails to block light from weed seeds, while applying too thick (over 4 inches) suffocates plant roots and breeds fungal artillery spores.
Optimal 3-Inch Depth Rule
For established perennial flowerbeds and shrub perimeters, 3 inches is the optimal depth balancing weed prevention and water infiltration.
Bags vs Bulk Economics
One cubic yard of mulch equals 13.5 bags (2.0 cu ft size). Once your garden needs exceed 3 to 4 cubic yards (approx 40–55 bags), ordering a bulk truck dump delivery is substantially cheaper.
Tree Flare Clearance
Avoid creating "mulch volcanoes" against tree trunks. Always keep mulch pulled back 3 to 6 inches from the tree root flare to avoid bark rot.
