“A 2- to 3-inch layer of wood chips provides good weed control. … Keep mulch 2 to 3 inches away from the stems of woody plants. This will prevent decay caused by wet mulch and rodent damage during the winter. … Newly planted trees require a circle of mulch 3 to 4 feet in diameter; however, do not pile mulch against the trunk. For established trees in lawns create a circle of mulch about 2 feet in diameter for each inch of trunk diameter. … Many wood and bark mulches are composed of fine particles and should not be more than 2 to 3 inches deep. Excessive amounts of these fine-textured mulches can suffocate plant roots, resulting in yellowing of the leaves and poor growth. … Coarse-textured mulches such as pine bark nuggets allow good air movement through them and can be as deep as 4 inches. … There are 27 cubic feet in a cubic yard. One cubic yard will cover a 324-square-foot area with an inch of mulch.”

From Pallets to Lawn: Understanding How Many Square Feet Are in a Pallet of Sod
Checked: 2026-09-29

“At Bethel Farms, one pallet of sod covers approximately 400 square feet, making it easy to plan your project. However, not all sod pallets are the same. Depending on the farm, grass type, and how the sod is cut and stacked, coverage can range from 400 to 500 square feet or more. … A standard pallet generally contains about 150 to 170 sod pieces, depending on the size of each slab. … Example: 2,000 sq ft ÷ 400 = 5 pallets Step 4: Add extra sod. Order an additional 5–10% extra sod to account for trimming, waste, and irregular edges.”
