Mulch calculator for Arkansas
Get bag and yard totals for all your landscape beds, with depth advice to support healthy plants.
Enter your project dimensions
There are 27 cubic feet in a cubic yard of mulch, equal to 13.5 bags sized at 2-cubic-foot from a garden center. That conversion is the key calculation on this page. Add the dimensions and selected depth for your beds to see the bulk cubic-yard total alongside its bag equivalent, making a store comparison easier. Shredded hardwood mulch is relatively light at around 600 lb per yard, and it is sold by volume, with bulk delivery not based on weight.
Plan mulch for landscape beds
- Record the dimensions of every bed in feet, then total the results. For a round bed, measure across its diameter and select circle mode to calculate the area.
- For an existing layer, apply 2 inches as a touch-up; use 3 inches when starting with bare or new beds. Once depth exceeds 4 inches, roots can be deprived of air.
- Use the result for bulk by reading cubic yards, or compare store bags using 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 sizes
| 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 mulch and bags
Ten bags marks the usual break point. Bags work well below that amount, while bulk is usually cheaper above it, and free delivery takes truck rental out of the equation. After hauling 15 bags home, it is easy to see the difference. Have one yard delivered, cover any remaining material with a tarp, and the job is finished.
Mulch depths for plant health
- After loosening last year's mulch with a rake, add 2 inches over it.
- Apply 3 inches over bare ground to reduce weed sprouting and help the soil keep moisture through July.
- To prevent bark damage and rodent shelter, leave an uncovered ring 3 to 6 inches around each trunk. Bark can decay when mulch rests against it. Shape the mulch like a flat donut, not a volcano.
- Keep every mulch layer at 4 inches or less. Deep mulch that stays wet cuts off air to roots.
- Choose playground-certified chips for play surfacing instead of landscape shred, keeping the material at least 6 inches deep.
Select a mulch type
This calculator uses shredded hardwood as its default. It interlocks well enough to remain on gentle slopes. Chips and nuggets may last longer, but heavy rain can float and spread them. Dyed mulch retains its color while taking longer to break down. All types use identical volume calculations, so quantity stays the same; appearance and refresh timing are what differ.
On delivery day
Three yards of mulch makes a pile roughly the size of a small car. Before delivery, open up a parking-space-sized spot on the driveway and place a tarp beneath the load because shredded mulch can mark fresh concrete. Put it out over the beds in a week or two, since a large pile can heat and turn sour if it sits for a month. Plan on 30 to 45 minutes with a wheelbarrow per yard, and save the last half-yard for the overlooked beds behind the garage.
