How much mulch do I need for a 8×12 bed?
≈ 12 bags (2 cu ft)
That’s about 0.89 cubic yards to cover a 8×12 bed at a 3″ depth.
A 8 ft × 12 ft bed is 96 square feet. At a 3-inch mulch depth (the sweet spot for weed control + moisture), that’s 24.0 cubic feet — about 12 standard 2-cubic-foot bags, or 0.89 cubic yards in bulk.
| Bed area | 96 sq ft |
| Depth | 3 in |
| Volume | 0.89 cu yd (24.0 cu ft) |
| 2-cu-ft bags | 12 bags |
Bulk (by the yard) is usually cheaper above ~10 bags. Refresh 1–2″ yearly rather than re-mulching full depth.
