The amount of mulch needed to cover a garden area depends on the texture and density of the mulch material. Over time, the mulch settles, compacts and decomposes. One cubic yard of mulch equals 27 cubic feet.

## Expert Insight

Robert Black, Edward Gilman, Gary Knox and Kathleen Rupert, horticultural expert contributors to "Your Florida Landscape" mention that mulches are maintained between 2 to 4 inches in depth. Small-particle mulches like sawdust need to be maintained between 2 to 3 inches in depth after settling, while coarse mulch materials, such as shredded bark, are maintained up to 4 inches in depth.

## Calculations

Based on mathematical explanations in "Your Florida Landscape," the depth of the mulch layer determines how much soil area a cubic yard of mulch covers. If applied in a 4-inch layer, 1 cubic yard covers 81 square feet. Scattered at a depth of 3 inches, a cubic yard of mulch covers 108 square feet, and a 2-inch layer covers 135 square feet.
