Calculation method
How the estimate is built.
The bed area multiplied by mulch depth gives cubic feet. We convert that to bulk cubic yards and separately round bagged mulch up to full bags for easy price comparison.
Field notes
Use the estimate well.
Keep mulch a few inches away from trunks, stems, siding, and weep holes.
Bulk delivery is often cheaper for larger beds, while bags can be easier for small touch-ups.
