On the defaults — 1050 square feet at a 3-inch depth with 10% waste — coconut husk mulch needs 1155.00 square feet of coverage, which is 10.69 cubic yards exact, so order 11 cubic yards. This is reference table #481 — the coconut husk version of the mulch chart, with a calculator on top and a 16-row lookup table below, following the stone-mulch-chart page, the wood-chip-mulch-chart page, the bamboo-mulch-chart page, and the cocoa-mulch-chart page.
Put your coconut husk mulch area, depth and waste in: 1050 sq ft at 3-inch depth with 10% waste needs 1155.00 sq ft — 10.69 cubic yards exact, order 11.
It means 1155.00 square feet of ground — the 1050 square feet you measured plus 10% waste — covered 3 inches deep in coconut husk. One cubic yard covers 324 square feet at 1 inch, so at 3 inches each yard covers 108.0 square feet, and 1155.00 divided by 108.0 is 10.69 yards. You cannot order 0.69 of a yard from a bulk supplier in practice, so the order rounds up to 11: the extra 0.31 of a yard is topping-up, not waste, because husk settles into the gaps between chunks as it beds in.
| Output | Formula | What it means |
|---|---|---|
| Needed area | area × (1 + waste ÷ 100) | 1155.00 sq ft — 1050 × 1.10. |
| Exact cubic yards | needed area × depth ÷ 324 | 10.69 — 1155.00 × 3 ÷ 324. |
| Order | exact cubic yards rounded up | 11 cubic yards — the next whole yard above 10.69. |
| Coverage per yard | 324 ÷ depth | 108.0 sq ft per yard at 3 inches. |
| Needed area at 0% waste | area × 1.00 | 1050.00 sq ft — no allowance added. |
| Area behind a target exact figure | target × 324 ÷ depth ÷ (1 + waste ÷ 100) | 1050 sq ft — 10.69 × 324 ÷ 3 ÷ 1.10. |
| Depth behind a target exact figure | target × 324 ÷ needed area | 3 inches — 10.69 × 324 ÷ 1155.00. |
| Waste behind a target exact figure | (target × 324 ÷ depth ÷ area − 1) × 100 | 10% — (10.69 × 324 ÷ 3 ÷ 1050 − 1) × 100. |
First, measure only the beds the husk will actually cover: paths, lawn and bare soil inside your measurement inflate the order by their full area times depth. Second, pick the depth for husk, not for bark: husk chunks lock together and resist washing out, so 3 inches of husk behaves like a deeper layer of a finer mulch, and copying a bark depth overstates the order. Third, keep the waste allowance honest on slopes and open ground: husk is light, wind moves it before it beds in, and a flat-ground 10% can run short on an exposed bank.
Area 1050 square feet, depth 3 inches, waste 10%. Needed area: 1050 × 1.10 = 1155.00 square feet. Exact yards: 1155.00 × 3 ÷ 324 = 10.69 cubic yards. Order: 11 cubic yards. At 4 inches instead, the same area needs 14.26 yards exact — order 15 — because one more inch across 1155.00 square feet is 1155.00 ÷ 324 = 3.56 extra yards. Depth is the lever that moves this chart fastest.
Every row below is the same formula at 10% waste: needed area is area × 1.10, exact cubic yards are needed area × depth ÷ 324, and the order is the exact figure rounded up. Rows vary in both area and depth, so a shallow small bed and a deep large one can both be read off directly. Find your row, or use the calculator above for any size the table does not list.
| Area (sq ft) | Depth (inches) | Needed area (sq ft) | Exact cubic yards | Order |
|---|---|---|---|---|
| 200 | 2 | 220.00 | 1.36 | 2 cubic yards |
| 350 | 3 | 385.00 | 3.56 | 4 cubic yards |
| 500 | 2 | 550.00 | 3.40 | 4 cubic yards |
| 250 | 4 | 275.00 | 3.40 | 4 cubic yards |
| 650 | 3 | 715.00 | 6.62 | 7 cubic yards |
| 400 | 4 | 440.00 | 5.43 | 6 cubic yards |
| 850 | 2 | 935.00 | 5.77 | 6 cubic yards |
| 550 | 3 | 605.00 | 5.60 | 6 cubic yards |
| 1050 | 2 | 1155.00 | 7.13 | 8 cubic yards |
| 700 | 4 | 770.00 | 9.51 | 10 cubic yards |
| 450 | 5 | 495.00 | 7.64 | 8 cubic yards |
| 900 | 3 | 990.00 | 9.17 | 10 cubic yards |
| 1200 | 3 | 1320.00 | 12.22 | 13 cubic yards |
| 600 | 4 | 660.00 | 8.15 | 9 cubic yards |
| 800 | 4 | 880.00 | 10.86 | 11 cubic yards |
| 1500 | 4 | 1650.00 | 20.37 | 21 cubic yards |
At 0% waste, 1050 square feet at 3 inches needs 9.72 yards exact — order 10. At 4 inches with 10% waste, the same area needs 14.26 yards exact — order 15. At 1250 square feet with 3 inches and 10% waste, the order is 12.73 yards exact — order 13. At 850 square feet with 3 inches and 10% waste, the order is 8.66 yards exact — order 9. Each branch changes exactly one input, so the difference from 10.69 isolates that input.
The area behind 10.69 yards is 1050 square feet: at 950 square feet the figures are 9.68 yards exact — order 10, and at 1150 square feet they are 11.71 yards exact — order 12. The depth behind 10.69 yards is 3 inches: at 2 inches the figures are 7.13 yards exact — order 8, and at 4 inches they are 14.26 yards exact — order 15. The waste behind 10.69 yards is 10%: at 5% the figures are 10.21 yards exact — order 11, and at 15% they are 11.18 yards exact — order 12 — waste moves the exact figure here, changing the order only at the upper neighbor.
The defaults assume a flat 1050 square feet, a uniform 3-inch layer, and a 10% waste allowance. Real beds are not uniform: edges thin out, the ground underneath undulates, and husk poured thick in the middle and thin at the edges averages out only roughly. Zero square feet is the honest edge: 0.00 yards exact, order 0. Negative area, zero depth and negative waste are rejected — none of them describes a bed you can mulch. Re-measure after the first barrow loads if the pile looks wrong: catching a measurement error early beats ordering a second delivery.
A home gardener mulching beds with husk for the first time: the table gives the order without doing the 324 division by hand. A landscaper quoting a husk job: the calculator prices the job from the measured beds, and the waste line is the visible allowance the client can see. A nursery manager topping up display beds: husk lasts longer than bark, so the order is a multi-season decision, not an annual one. A community garden coordinator splitting a bulk delivery: the table lets each plot read its share off the same chart.
The arithmetic is exact for the inputs entered; the judgement is in the inputs. An area that includes paths, a depth guessed instead of measured, or a waste allowance copied from a different mulch will each move the answer by exactly the amount of the error. The model does not include compaction after heavy rain, wind loss on exposed ground, or the volume already on the bed from a previous mulch layer — measure the new layer only, and re-check the depth with a ruler in several spots after spreading.

Because one cubic yard is 27 cubic feet, and one inch of depth over one square foot is 1/12 of a cubic foot — so a yard covers 27 × 12 = 324 square feet at 1 inch deep. At 3 inches, divide 324 by 3: each yard covers 108.0 square feet.
Bulk mulch is ordered in whole yards, and rounding down would leave part of the bed uncovered. The extra 0.31 of a yard beds into the gaps between husk chunks and tops up thin spots, so the round-up is useful material, not over-ordering.
It is a comfortable default: husk settles less than soft mulches but is light enough to shift before it beds in. Use more on slopes, open ground, or beds with many edges, and less on flat, sheltered beds you can spread carefully.
Just the beds the husk will cover. Lawn, paths and bare soil need no mulch, and every square foot wrongly included adds depth ÷ 324 yards to the order — at 3 inches, about 0.01 yards per square foot, which adds up across a garden.
The formula is identical; only the depth choice and the settling differ. Husk chunks lock together and rot slowly, so a 3-inch husk layer lasts and behaves like a deeper fine mulch — do not copy a bark depth without thinking about what the husk layer actually needs to do.
Split it into rectangles and triangles, measure each, and add the areas. A rough single measurement of an irregular bed is the commonest cause of a short order — two careful rectangles beat one guessed outline.
