Mulch calculator for Vermont
Figure yards or bags for each landscape bed, with depth advice for plant health.
Enter your project dimensions
One cubic yard holds 27 cubic feet of mulch, equal to exactly 13.5 bags sized at 2 cubic feet from a garden center. That conversion is the reason for this page. Add the dimensions and desired depth for your beds below to see the bulk cubic-yard total and its bag equivalent, giving you numbers to compare with a store trip. Shredded hardwood weighs around 600 lb per yard, making mulch a volume purchase, and bulk delivery is based on volume rather than weight.
Estimate mulch for garden beds
- Take each bed measurement in feet, then combine the totals. For circular beds, measure the diameter and use circle mode to find the area.
- For an existing mulch layer, select 2 inches. Use 3 inches in new beds or on exposed soil, since depths beyond 4 inches can restrict air to roots.
- The result gives bulk quantity in cubic yards, plus a bag comparison calculated at 13.5 bags per yard.
Bags (2 cu ft) = cubic yards × 13.5
Coverage guide
| Depth | 1 cubic yard covers | 10 bags (2 cu ft) cover |
|---|---|---|
| 1 inch | 324 sq ft | 240 sq ft |
| 2 inches | 162 sq ft | 120 sq ft |
| 3 inches | 108 sq ft | 80 sq ft |
| 4 inches | 81 sq ft | 60 sq ft |
Common order amounts
| Project | Typical size | Depth | Cubic yards | ≈ Bags |
|---|---|---|---|---|
| Foundation beds along the house | 40 x 3 ft | 3" | 1.1 yd³ | 15 bags |
| Four tree rings | 4 ft across each | 3" | 0.5 yd³ | 6 bags |
| All beds, average yard | ≈ 500 sq ft | 3" | 4.6 yd³ | 63 bags |
| Annual refresh of the same beds | ≈ 500 sq ft | 1.5" | 2.3 yd³ | 31 bags |
| Playground surface | 15 x 15 ft | 6" | 4.2 yd³ | 56 bags |
Comparing bulk and bags
At Ten bags, the buying method changes. Bags work well below that point; above it, bulk is usually the lower-price choice, and free delivery means there is no need to rent a truck. If 15 bags have already gone home, compare the totals before buying more. Get One yard delivered, cover any remaining material with a tarp, and finish the project.
Depths for plant health
- After loosening last year's mulch with a rake, add 2 inches over it.
- Start with 3 inches over bare soil to help prevent weed seeds from sprouting and retain moisture through July.
- Leave an exposed ring 3 to 6 inches wide around each tree trunk. Bark can rot and rodents can shelter where mulch touches it. Keep the mulch low and level, like a donut rather than a volcano.
- Keep mulch at 4 inches or less in every area. A deep layer that remains wet limits air around plant roots.
- Landscape shred is not for play zones; install playground-certified chip to a minimum depth of 6 inches.
Mulch type options
The calculator is set for shredded hardwood, which interlocks and stays put on mild slopes. Chips and nuggets may remain intact for one or two additional seasons, though a downpour can make them float and spread. Dyed mulch maintains its color while decomposing more slowly. Quantity calculations are the same for every option, so the type affects appearance and replacement timing, not the amount ordered.
Preparing for delivery
A three-yard mulch pile takes up roughly the space of a small car. Clear a driveway area about the size of a parking space, and place a tarp before the load is tipped because shredded mulch can stain fresh concrete. Spread it over the following week or two. When left in a large pile for a month, mulch can heat internally and turn sour. Allow 30-45 minutes of wheelbarrow work for each yard, reserving the final half-yard for overlooked beds behind the garage.
