How much mulch for 50 square feet?
At 3 inches deep, 50 square feet needs 0.46 cubic yards of mulch, or about 7 bags (2 cu ft each).
2 to 3 inches is right for most beds; 4 inches for paths or heavy weed pressure.
| Depth | Cubic yards | 2 cu ft bags | 3 cu ft bags |
|---|---|---|---|
| 2 in | 0.31 | 5 | 3 |
| 3 in | 0.46 | 7 | 5 |
| 4 in | 0.62 | 9 | 6 |
1 cubic yard = 27 cubic feet. Bulk delivery is usually cheaper than bags above about 1 to 2 cubic yards.
