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

Best mulch depth

Aim for 2 to 3 inches. Refreshing existing beds often needs only an inch on top. Do not pile mulch against trunks; the ’volcano’ mound traps moisture against the bark.

Buying mulch

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.

Timing the job

Plan deliveries for a dry stretch so the pile and the ground are workable. Early spring mulching suppresses weeds before they sprout, while fall soil work gives beds time to settle before planting.

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.

Checking quality

Squeeze a handful: quality topsoil holds together loosely and breaks apart, rather than forming a sticky ball of clay or falling apart like sand. Avoid soil that smells sour or contains debris.

Common mistakes

Buying by the bag for a large area is the classic error: dozens of bags cost far more than a bulk yard. Another is skipping compost or using unscreened soil full of clods and roots. Spreading soil when it is soaking wet compacts it and makes it hard for roots and water to move.
