What does 777.13 cubic yards of tea leaf mulch mean?
It means a 76300 square foot bed, once the 10% waste allowance is added, needs 83,930.00 square feet of cover at 3 inches deep — 20,982.50 cubic feet, which is 777.13 cubic yards. Because mulch is sold by the whole yard, you order 778 cubic yards: the exact figure sits 0.87 yards below the next whole yard, so the order carries 0.87 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 518.09 yards, and at 4 inches it would need 1036.17 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: tea leaves are fine and papery, so they settle into a mat 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 tea leaf: even well-laid tea leafs 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 778 yards carries 0.87 yards of headroom, which covers ordinary spillage on a bed like this one. The tea leaves themselves are leaves left after tea is brewed — the mulch comes from the kitchen, not from timber.
Worked example
Area 76300 sq ft, depth 3 inches, waste 10%. Area needed: 76300 × 1.10 = 83,930.00 sq ft. Exact volume: 83,930.00 × 3 ÷ 324 = 777.13 cubic yards. Order: round 777.13 up to 778 cubic yards. Drop the waste to 0% and the exact volume falls to 706.48 yards, order 707; raise the waste to 5% and it is 741.81 yards, order 742; raise it to 15% and it is 812.45 yards, order 813. Drop the depth to 2 inches and it falls to 518.09 yards, order 519; raise it to 4 inches and it climbs to 1036.17 yards, order 1037. Depth moves the answer faster than waste does, because every inch adds a full layer across the whole bed.
Tea leaf 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.

Every branch, checked
A 76300 square foot bed at 3-inch depth with 0% waste gives 706.48 cubic yards exact, order 707 cubic yards. The same bed at 2-inch depth with 10% waste gives 518.09 cubic yards exact, order 519 cubic yards. A 76200 square foot bed at 3-inch depth with 10% waste gives 776.11 cubic yards exact, order 777 cubic yards. The same bed at 4-inch depth with 10% waste gives 1036.17 cubic yards exact, order 1037 cubic yards. Each branch changes exactly one input, so the difference from 777.13 isolates that input.
The reverses, worked backwards
The area behind 777.13 cubic yards is 76300 sq ft: at 76200 sq ft the figures are 776.11 cubic yards exact, order 777 cubic yards, and at 76400 sq ft they are 778.15 cubic yards exact, order 779 cubic yards. The depth behind 777.13 cubic yards is 3 inches: at 2 inches the figures are 518.09 cubic yards exact, order 519 cubic yards, and at 4 inches they are 1036.17 cubic yards exact, order 1037 cubic yards — one inch either way moves the order by about 259.04 yards. The waste behind 777.13 cubic yards is 10%: at 5% the figures are 741.81 cubic yards exact, order 742 cubic yards, and at 15% they are 812.45 cubic yards exact, order 813 cubic yards.
What the defaults assume
The defaults assume a flat 76300 square foot bed, a uniform 3-inch layer, and a 10% waste allowance. Real tea leaf beds are rarely simple rectangles: paths and tree trunks eat into the area, and tea leafs 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 tea leaf: the 76300 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 tea leaf job: the waste column protects the quote, and the order column is the number given to the supplier. A homeowner laying tea leaf 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 tea leafs 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 leaf debris at the edges, delivery minimums, or the gaps between tea leafs — a supplier may sell only in whole yards or charge extra below a minimum, so confirm the order quantity with the supplier. Tea leaves are safe around most garden plants, and as kitchen waste they feed the soil as they rot; leaves are fine and tannin-rich, so a thin fresh layer can also mat and shed water — mix them with coarser mulch 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 tea leaf mulch really be?
Three inches is the standard bed layer on this page, and 2 inches suit paths and top-ups. Tea leafs are light and crisp, so a 3-inch spread settles into a mat quickly, though the leaves still break down over time; if thin spots appear, top them up rather than re-laying the whole bed.
Does tea leaf mulch introduce weed seeds?
Tea leafs 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 778 yards when the exact figure is 777.13?
Because mulch is sold by the whole yard, and 777.13 rounds up to 737 — the order carries 0.87 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. Tea leafs break down readily, so use the tea leaf rows for tea leaf and the matching chart for stone or wood chips.
