How much mulch do I need for a 10×30 bed?
≈ 38 bags (2 cu ft)
That’s about 2.78 cubic yards to cover a 10×30 bed at a 3″ depth.
A 10 ft × 30 ft bed is 300 square feet. At a 3-inch mulch depth (the sweet spot for weed control + moisture), that’s 75.0 cubic feet — about 38 standard 2-cubic-foot bags, or 2.78 cubic yards in bulk.
| Bed area | 300 sq ft |
| Depth | 3 in |
| Volume | 2.78 cu yd (75.0 cu ft) |
| 2-cu-ft bags | 38 bags |
Bulk (by the yard) is usually cheaper above ~10 bags. Refresh 1–2″ yearly rather than re-mulching full depth.
