How Much Mulch Do You Need?
One cubic yard of mulch covers 108 square feet at a 3-inch depth ($27\text{ cu ft} / 0.25\text{ ft} = 108\text{ sq ft}$):
- Formula: $$\text{Cu Yards} = \frac{\text{Length (ft)} \times \text{Width (ft)} \times (\text{Depth in} / 12)}{27}$$
- Bags vs Bulk: If your project requires more than 2 cubic yards (~27 two-cubic-foot bags), buying bulk delivery from a local landscape supply yard is usually 40-50% cheaper.
