Five cubic yards of mulch weighs about 4,500 pounds dry — figure roughly 900 lbs per cubic yard, more after rain. Bark soaks up water quickly, so a spring load that sat through a wet week can run noticeably heavier than the same volume in August.
Mulch weight quick reference
| Volume | Approx. dry weight |
|---|---|
| 1 cubic yard | ~900 lbs |
| 5 cubic yards | ~4,500 lbs |
| 10 cubic yards (a full load) | ~9,000 lbs |
Those numbers are exactly why bulk mulch travels by dump truck instead of a hatchback — and why 5 yards becomes roughly 45–70 heaped wheelbarrow trips once it lands in your driveway. See bulk mulch by the yard and size your beds with the material calculator.
