What does 726.20 cubic yards of clover hull mulch mean?
It means a 71300 square foot bed, once the 10% waste allowance is added, needs 78,430.00 square feet of cover at 3 inches deep — 19,607.50 cubic feet, which is 726.20 cubic yards. Because mulch is sold by the whole yard, you order 727 cubic yards: the exact figure sits 0.80 yards below the next whole yard, so the order carries 0.80 yards of headroom for spillage and uneven ground. At 3 inches, one cubic yard covers 108.0 square feet, so the same bed at 2 inches would need only 484.14 yards, and at 4 inches it would need 968.27 yards.

Three things to check before you trust the number
First, measure the bed honestly: length times width for each bed, added together, with L-shaped beds split into rectangles. A guessed area moves the order by the same percentage as the guess. Second, keep the depth honest: clover hulls are sturdy and fibrous, so they settle into a soft layer that holds moisture well, but even a firm layer thins as it breaks down and the thin spots need topping up through the season. Third, do not skip the waste allowance on clover hull: even well-laid clover hulls blow about at the edges, and spillage and uneven ground still eat into the load, so the 10% allowance is the difference between finishing the bed and running short with the truck already gone. The headline order of 727 yards carries 0.80 yards of headroom, which covers ordinary spillage on a bed like this one. The clover hulls themselves are hulls left after the clover harvest — the mulch comes from clover plants, not from timber.
Worked example
Area 71300 sq ft, depth 3 inches, waste 10%. Area needed: 71300 × 1.10 = 78,430.00 sq ft. Exact volume: 78,430.00 × 3 ÷ 324 = 726.20 cubic yards. Order: round 726.20 up to 727 cubic yards. Drop the waste to 0% and the exact volume falls to 660.19 yards, order 661; raise the waste to 5% and it is 693.19 yards, order 694; raise it to 15% and it is 759.21 yards, order 760. Drop the depth to 2 inches and it falls to 484.14 yards, order 485; raise it to 4 inches and it climbs to 968.27 yards, order 969. Depth moves the answer faster than waste does, because every inch adds a full layer across the whole bed.
Clover hull mulch lookup table
Every row below applies 10% waste to the area first, then divides by 324: yards = area needed × depth ÷ 324, rounded up to the next whole yard for the order. Find your bed size and depth, read across, and order the last column.
| Area (sq ft) | Depth (inches) | Area needed (sq ft, 10% waste) | Exact (cubic yards) | Order |
|---|
| 300 | 2 | 330.00 | 2.04 | 3 cubic yards |
| 300 | 3 | 330.00 | 3.06 | 4 cubic yards |

Every branch, checked
A 71300 square foot bed at 3-inch depth with 0% waste gives 660.19 cubic yards exact, order 661 cubic yards. The same bed at 2-inch depth with 10% waste gives 484.14 cubic yards exact, order 485 cubic yards. A 71200 square foot bed at 3-inch depth with 10% waste gives 725.19 cubic yards exact, order 726 cubic yards. The same bed at 4-inch depth with 10% waste gives 968.27 cubic yards exact, order 969 cubic yards. Each branch changes exactly one input, so the difference from 726.20 isolates that input.
The reverses, worked backwards
The area behind 726.20 cubic yards is 71300 sq ft: at 71200 sq ft the figures are 725.19 cubic yards exact, order 726 cubic yards, and at 71400 sq ft they are 727.22 cubic yards exact, order 728 cubic yards. The depth behind 726.20 cubic yards is 3 inches: at 2 inches the figures are 484.14 cubic yards exact, order 485 cubic yards, and at 4 inches they are 968.27 cubic yards exact, order 969 cubic yards — one inch either way moves the order by about 242.07 yards. The waste behind 726.20 cubic yards is 10%: at 5% the figures are 693.19 cubic yards exact, order 694 cubic yards, and at 15% they are 759.21 cubic yards exact, order 760 cubic yards.
What the defaults assume
The defaults assume a flat 71300 square foot bed, a uniform 3-inch layer, and a 10% waste allowance. Real clover hull beds are rarely simple rectangles: paths and tree trunks eat into the area, and clover hulls at the edges blow into the lawn, so measure the planted area only and keep the waste allowance on sloped ground. Zero square feet is the honest edge: 0.00 cubic yards exact, order 0. A depth of zero or below, a negative area, or a negative waste allowance is rejected, because none of them describes a real bed.
Who uses this
A gardener dressing beds and paths with clover hull: the 71300 square foot headline is a large garden bed or a long drive, and the table covers everything from a 300 square foot border to a 3200 square foot yard. A landscaper quoting a clover hull job: the waste column protects the quote, and the order column is the number given to the supplier. A homeowner laying clover hull on a path: the 3-inch rows are the bed depths, and the 2-inch rows are the path depths. A community garden coordinator splitting a bulk delivery: each plot reads its own row, and the orders add up to the truckload.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is in the inputs. A guessed area, a depth measured before the clover hulls settle, or a skipped waste allowance will each move the answer by exactly the amount of the error, every load. The model does not include hull washing at the edges, delivery minimums, or the gaps between clover hulls — a supplier may sell only in whole yards or charge extra below a minimum, so confirm the order quantity with the supplier. Clover hulls are safe around most garden plants, but a thin fresh layer can scatter in wind, so top up established beds through the season rather than laying one thick layer and leaving it.

Frequently asked questions
Why does the table apply waste to the area first?
Because waste is lost cover: spillage, scattering and uneven ground mean you need more covered area than the bed measures. Adding 10% to the area, then converting to yards, keeps the waste in the same units as the bed. Applying it after the conversion gives the same number here, but the area-first order keeps the table readable.
How deep should clover hull mulch really be?
Three inches is the standard bed layer on this page, and 2 inches suit paths and top-ups. Clover hulls are sturdy and fibrous, so a 3-inch spread settles quickly, though the hulls still break down over time; if thin spots apcloverr, top them up rather than re-laying the whole bed.
Does clover hull mulch introduce weed seeds?
Clover hulls are organic, so a load can carry a few weed seeds; weeds can still root in the dust and debris that collects on top of it, so use fabric underneath and clear the debris. This calculator prices volume only and does not judge the gardening choice.
What if my bed is not a rectangle?
Split it into rectangles, measure each, and add the areas before entering the total. A circle uses radius times radius times 3.14. Guessing one number for an irregular bed is the most common reason orders come up short.
Why order 727 yards when the exact figure is 726.20?
Because mulch is sold by the whole yard, and 726.20 rounds up to 727 — the order carries 0.80 yards of headroom for spillage and uneven ground. That headroom is the buffer the exact figure does not have.
Can I use this chart for other mulch types?
The volume math is the same for any loose mulch — area, depth and waste convert the same way — but settling and coverage differ by material. Clover hulls break down readily, so use the clover hull rows for clover hull and the matching chart for stone or wood chips.
