One cubic yard of mulch covers about 108 square feet at 3 inches deep, or 162 square feet at 2 inches.

How deep to mulch

Two to three inches is the usual target for shredded or chipped mulch. Deeper than about 4 inches can hold too much moisture and keep air from roots. Keep mulch a few inches back from tree trunks and plant stems.

Bulk vs bags

Order bulk at this size. A 2 cubic foot bag is 1/13.5 of a yard, so 13 to 14 bags equal one cubic yard.

Measuring accurately

Measure each bed or area in feet and multiply length by width for square feet. For curved beds, a rough rectangle around the shape overestimates; split it into smaller shapes instead. Measure the depth you actually want to add, not the total depth of the bed if some soil is already there.

Weight and hauling

Soil is heavy and mulch is bulky. A half-ton pickup can usually carry only a fraction of a yard of soil safely, even if it looks like more would fit. Delivery is often the safer and faster option.

Checking quality

Good bulk soil is dark, crumbly and free of trash, large rocks and weed roots. Ask whether it is screened and whether compost is blended in. If possible, look at the pile before ordering or ask for a sample.

Delivery and spreading

Ask the supplier where the truck can safely dump without crossing soft lawn or septic fields. Cover the pile if rain is coming. Spread with a flat shovel and a landscape rake, working from the far end back toward the pile.
