Mulch Coverage Guide

One cubic yard of mulch covers approximately 162 square feet at 2 inches deep, 108 sq ft at 3 inches, and 81 sq ft at 4 inches. A standard bag of mulch is 2 cubic feet and covers about 8 square feet at 3 inches deep. For areas over 200 sq ft, buying by the cubic yard (bulk delivery) is 40-60% cheaper per cubic foot than bagged mulch.

The ideal mulch depth is 2-4 inches. Less than 2 inches does not suppress weeds effectively. More than 4 inches traps moisture against plant stems and can cause rot. Keep mulch 3-4 inches away from tree trunks and plant stems — mulch volcanoes (piled against trunks) kill trees slowly by trapping moisture and encouraging bark decay.
