How much land will 1 cubic yard of mulch cover?

By S.F. Heron ; Updated September 21, 2017
Garden centers sell mulch in bags or as loose bulk material.

Retailers sell mulch in cubic measurements of feet and yards and use the term "yard" to refer to a cubic yard measurement. One cubic yard of mulch covers 324 square feet of garden area to a 1-inch depth. This coverage equates to an 18-by-18-square-foot garden surface.
