How much mulch do you need?

A mulch calculator determines how many cubic yards of mulch or bark chips are needed to cover a garden bed to a specified depth. Mulch conserves moisture, suppresses weeds, moderates soil temperature, and improves soil as it decomposes.

💡

Tip: Buy mulch by the cubic yard from bulk suppliers when covering more than ~6 cubic yards (162 sq ft at 3"). Bulk mulch is 30–50% cheaper per cubic yard than bagged. Use a tarp to protect your driveway.

  1. 1Volume = Length (ft) × Width (ft) × Depth (in) / 324 = cubic yards
  2. 2Rule: 1 cubic yard covers 324 sq ft at 1 inch depth
  3. 3Recommended depth: 2–4 inches (too thin = weeds, too thick = root rot)
  4. 4Around trees: keep mulch 3–6 inches away from trunk ("mulch volcano" harms trees)

Fun Fact

The US uses about 20 million cubic yards of mulch per year. Wood chip mulch from arborists is often free — many tree companies will deliver chips directly to homeowners rather than paying disposal fees.
