How Many Garlic Cloves Per Acre?
Work it out for your farm
Want the cost side? The labour calculator puts your wage and your crew's hand-planting rate against the planter.
Short answer: between roughly 98,000 and 261,000 cloves per acre, depending on your spacing. At the common 6″ × 6″ layout it is 174,240 cloves per acre.
The chart
| In-row × between-row | Cloves per acre | PL-22 running hours per acre* |
|---|---|---|
| 4″ × 6″ | 261,360 | 187 |
| 4″ × 8″ | 196,020 | 140 |
| 6″ × 6″ | 174,240 | 124 |
| 6″ × 8″ | 130,680 | 93 |
| 8″ × 8″ | 98,010 | 70 |
*At about 1,400 cloves an hour — two riders placing roughly 700 each, with a third person driving the tractor. Hand-planting rates vary too widely to put in a chart; see below.
How to work it out for any spacing
An acre is 43,560 square feet, or 6,272,640 square inches.
cloves per acre = 6,272,640 ÷ (in-row spacing × between-row spacing)At 5″ × 7″: 6,272,640 ÷ 35 = 179,218 cloves per acre.
If you plant in beds with pathways, calculate the planted area only. A 4-foot bed with a 2-foot path is 67% planted ground, so multiply your result accordingly.
A note on seed weight
Growers usually want this in pounds, not cloves, and that is where a general chart stops being useful. Cloves per pound swings enormously by variety and by bulb grade — a hardneck like Music runs far fewer, larger cloves per pound than a softneck, and your own seed grade matters more than any published average.
The honest method is to weigh and count a sample of your own seed stock: crack out a pound, count the plantable cloves, and put that number in the calculator at the top of this page. It turns cloves into pounds for your spacing and acreage. That number is right for your seed, which no table can be.
What this means for planting day
Hand-planting rates depend on how much of the job is counted. Dropping cloves into a furrow somebody else opened is fast; making the hole, setting each clove root-down and covering it is not. Doug’s figure for the whole job is about 300 cloves per person per hour. Divide the chart figure by your own crew’s rate, measured over a full day, and you have your hand-planting labour-hours.
Now take one acre at 8″ × 8″: 98,010 cloves. On the PL-22 that is about 70 running hours, or 210 labour-hours counting both riders and the tractor driver. The planter comes out ahead on labour whenever a hand crew plants fewer than about 470 cloves per person per hour, counting the whole job — making the row, setting each clove root-down and covering it.
This is why garlic acreage on small farms tends to stall at two or three acres. It is usually not a land constraint. It is an October constraint: the crop goes in during a narrow window, competing with everything else on a diversified farm, and it goes in whether the weather cooperates or not.
Running it for your own farm
Our labour cost calculator takes these numbers, your labour rate and your own crew’s hand-planting rate, and works out what planting costs you by hand and on the machine.
If you want to go deeper, we wrote up the full comparison against hand-planting, including what a planter changes beyond labour-hours — a three-person crew you can actually find, every clove root-end down, and one frame that plants in October and harvests in July.
