How to read these citations
Volume (area × depth ÷ 324) is unit conversion: NIST states that 1 cubic yard is 27 cubic feet, and 12 inches make a foot, so one yard covers 324 square feet at 1 inch. Weight (1.35 tons per yard) is a moist, as-delivered planning factor. USDA NRCS bulk density is oven-dry and varies by texture — we cite it to show why a wet clay load is not the same as a fluffy compost blend, not to claim 1.35 is a lab measurement.
Price tables are national homeowner ranges from Angi, HomeGuide, and Lawn Love. They are not invoices and not a survey of your county. Sod pallet size is not a federal standard; we use 450 square feet because several growers publish that as a common cut, and we show the 400–600 range they also publish.
For the soil under your own lot, use the USDA Web Soil Survey rather than a state-wide paragraph. Corrections: contact.

- Iowa State University Extension and Outreach. How deep should the mulch layer be around trees and shrubs?. A 3–4 in layer of wood chips or shredded bark suits well-drained sites; 2–3 in on heavy soils. Keep mulch at least 6 in away from trunks.
- University of Illinois Extension. Proper Mulching Techniques (Tree Care Basics infosheet). Recommended mulch depth 2–4 in: composted material 2–3 in, coarse mulch 3–4 in. Keep at least 4 in away from the trunk; excess mulch mats and reduces water and oxygen penetration.
- University of Maryland Extension. Mulching Trees and Shrubs. Keep mulch shallow, 1–3 in, and about 3 in from the base of trunks. By material: bark and arborist wood chips 1–3 in, pine needles 2–3 in, shredded leaves 2–3 in, compost about 1 in.
- HomeGuide. How Much Does Landscaping Cost? (2026). Mulch $15–$65 per cubic yard delivered. Publisher’s rounded coverage figure: 110–120 sq ft per yard at 3 in. Bagged mulch $2–$7 per bag covering 7–9 sq ft.

- Cornell Waste Management Institute (Cornell University). On-Farm Composting Handbook, Appendix A — Table A.1 Typical Bulk Densities. Bulk density in pounds per cubic yard: wood chips 445–620, sawdust 350–450, loose leaves 300–400 (compacted 500–800). Dry wood mulch is roughly a fifth of the weight of the same volume of topsoil.
- Iowa State University Extension and Outreach. Using Mulch in the Garden. Generally 2–4 in, coarser mulches (wood chips) at the high end and finer mulches (grass clippings) at the low end. Apply in early spring once the ground warms and perennials emerge, or in fall as plants go dormant; mulching too early insulates cold soil. Mulch piled more than 2–4 in against a trunk (a mulch volcano) keeps bark wet and invites cankers, root rots, and moisture-loving insects; keep it under 4 in and feather it away from trunks.
- Washington State University Extension. Guide to Mulches (C075). Depth by material: wood chips 2–4 in and coarse or fine bark 2–3 in around trees and shrubs, sawdust 2–3 in, shredded leaves 2–3 in, pine needles 3–4 in or more, compost 1–3 in, grass clippings 2–3 in after drying, coffee grounds only ½ in. Keep bark and chips a few inches off trunks.
- The Backyard Pros (packaging-side figures). How Many Bags of Mulch Are on a Pallet?. A 40 × 48 in pallet takes 65–70 bags of 2 cu ft hardwood, straw, or pine bark; 70–80 of 1.5 cu ft, 50–60 of 2.8 cu ft, 40–50 of 3 cu ft. Loads are capped by a 4,600 lb weight limit and a 48–60 in stack height, so the count is a packaging decision that differs by retailer.
