About This Tool
This landscaping volume calculator determines the exact number of retail mulch bags or bulk cubic yards needed to cover your planting beds and garden borders. Enter your total flower bed area in square feet (length × width of beds), your target mulch application depth (2 inches for annual freshening, 3 inches for standard coverage, or 4 inches for intensive weed blocking), and your preferred bagged mulch packaging size (2.0 cu ft standard bags or 3.0 cu ft large contractor bags).\n\nThe engine calculates total volume in cubic feet by multiplying square footage by depth in feet (depth in inches divided by 12). It divides cubic feet by 27 to find bulk cubic yards, and divides by your selected bag volume to compute the exact number of bags to purchase at the garden center. All calculations run strictly in client-side JavaScript on your device.
How to Use
- 1
Enter the total flower bed area in square feet into the Flower Bed Area field.
- 2
Select your desired mulch layer depth in inches (typically 2 to 4 inches).
- 3
Choose your retail mulch bag volume (2.0 cubic feet or 3.0 cubic feet).
- 4
Review the total required bag count, cubic yards volume, and bulk yardage equivalent.
Frequently Asked Questions
How many bags of mulch make up a full cubic yard?
One cubic yard contains exactly 27 cubic feet. That equals 13.5 bags of 2-cubic-foot mulch (round up to 14) or 9 bags of 3-cubic-foot mulch.
How thick should mulch be in flower beds?
A 3-inch depth is recommended for most garden beds. It suppresses weed germination and retains soil moisture without smothering perennial root crowns.
