How Much Garlic to Plant: Seed Garlic Calculator

Plant one clove for every bulb of garlic you want to eat, plus enough extra cloves to grow next year’s seed. A kitchen that goes through 1 bulb a week needs 61 hardneck cloves: 52 bulbs to eat and 9 to replant. That is about 1.4 pounds of seed garlic and 16 square feet at 4 cloves per square foot, one 4×4 bed. Put your own numbers in the calculator.

Quick picks:

Plant 61 cloves. They grow 52 bulbs to eat and 9 bulbs to replant next year.

Cloves to plant61
Bulbs to eat52 a year
Bulbs to keep for seed9, enough for 63 cloves
Seed garlic to buy the first yearabout 9 bulbs
Seed garlic by weightabout 1.4 lb
Order in half-pound bags1.5 lb
Space at 4 per square foot16 squares (16 sq ft)
4×4 beds (up to 64 cloves each)1
4×8 beds (up to 128 cloves each)1

Enter the household total, not a per-person number. Change cloves per bulb and per pound if your seed company lists them for your variety.

Worked examples

Here is the calculator run for four kitchens that grow their own seed garlic each year. Hardneck uses 7 cloves per bulb and 42.5 cloves per pound, softneck uses 14 and 67.5; where those numbers come from is further down. Space is at 4 cloves per square foot.

1 bulb a day (365 a year)394295.8 lb, order 6 lb99 squares, four 4×8 beds

Softneck needs fewer bulbs held back because each bulb carries more cloves, and fewer pounds because the cloves are smaller.

How the calculator gets its numbers

  1. One clove grows one bulb. Each clove you plant becomes a full head by the next summer, as my garlic per square foot page puts it, and Utah State University Extension says the same: each planted clove produces one bulb. So the bulbs you want to eat are the first part of the cloves you plant.
  2. Add seed for next year. Seed garlic costs more up front, but as my How to Grow Garlic guide says, you can save some of your harvest to replant, and the bulbs to save are the largest ones. If each bulb you keep breaks into 7 cloves, it replants its own spot in the bed and 6 more. So the bulbs to keep are the bulbs you eat divided by 6, rounded up. For 52 bulbs: 52 / 6 = 8.7, so keep 9, and plant 52 + 9 = 61 cloves. Those 9 bulbs give 63 cloves the next fall, enough to plant 61 again.
  3. Turn cloves into pounds. 61 cloves / 42.5 cloves per pound = 1.4 pounds. Wood Prairie sells seed garlic in half-pound and one-pound bags, and Sow True Seed sells it in half pounds and pounds, so the calculator rounds up to the next half pound: 1.5 pounds.
  4. Turn cloves into space. I plant garlic four to a square, 6 inches apart. 61 / 4 = 15.25, so 16 squares. A 4×4 bed has 16 squares and fits up to 64 cloves; a 4×8 bed has 32 and fits up to 128. Bed-by-bed planting steps are in How to Plant Garlic in Raised Beds.

The first year you buy all 61 cloves as seed garlic. After that, the 9 bulbs you keep at harvest are next year’s seed, and you only buy again if you want a new variety or a bigger bed.

Cloves per bulb and per pound: what the sources say

Clove counts are the soft spot in any garlic math. They change with the variety and bulb size, and Johnny’s Selected Seeds notes that its cloves per pound are averages that vary each year with weather and growing conditions. Here is what each source gives:

SourceHardneckSoftneck
University of Maryland Extension6-7 cloves per bulb; 6-7 large bulbs per poundnot given
Iowa State University ExtensionRocambole 6-11 cloves, Purple Stripe 8-12, Porcelain 4not given
South Dakota State University Extension4-5 large cloves per headup to 15-18 cloves per head
Ohio State University Extensionfewer but larger clovesartichoke types usually 14-20 per head
University of Georgia Extensionnot givenartichoke and silverskin 12-20 per bulb; Inchelium Red 8-22
Johnny’s Selected Seeds5-8 cloves per head, about 40 per pound7-8 cloves per head, about 45 per pound
Sow True Seed35-50 cloves per pound50-70 cloves per pound
Wood Prairie variety pages3-8 cloves per bulb, 20-65 per pound80-90 per pound
Calculator default7 per bulb, 42.5 per pound14 per bulb, 67.5 per pound

The defaults are the middle of each range. Hardneck runs from 3 to 12 cloves per bulb, a midpoint of 7.5, and softneck from 7 to 22, a midpoint of 14.5. Both are rounded down, because the smallest cloves in a bulb are the ones you eat, not plant. Per pound, hardneck runs from 20 to 65 (midpoint 42.5) and softneck from 45 to 90 (midpoint 67.5). The ranges are wide, so if your seed company prints a number for your variety, use it.

Cloves per pound by variety

Wood Prairie, where I get seed garlic, prints a clove count on each of its organic seed garlic pages:

VarietyType, as listedCloves per bulbCloves per pound
MusicPorcelain hardneck5-8about 30
German Extra-HardyPorcelain hardneck3-520-40
Georgian FirePorcelain hardnecknot listedabout 30
Chesnok RedPorcelain hard-necknot listed50-65
Red RussianRocambole hardnecknot listedabout 40
PhillipsRocambole hardnecknot listedabout 40
LyubashaHard-neck4-6not listed
SicilianArtichoke softnecknot listed80-90
Inchelium RedSoftnecknot listed80-90

Varieties with a few big cloves per bulb weigh out to fewer cloves per pound. A pound of Music is about 30 cloves, not the 42 the hardneck default gives, so for Music set cloves per pound to 30 and cloves per bulb to 6 (the middle of 5-8, rounded down). Wood Prairie ships seed garlic in half-pound and one-pound bags in time for fall planting, and code PMG5 takes 5 percent off.

How much garlic per person?

The only per-person figure the sources give is a national average. Penn State Extension puts U.S. garlic consumption at about 2.5 pounds per person a year. It also says only about 30 percent of U.S. garlic production is sold fresh and the rest is dehydrated, so that average may include dried garlic, not just fresh bulbs. Treat it as a rough ceiling. At University of Maryland Extension’s 6-7 large hardneck bulbs per pound, 2.5 pounds is about 15 to 18 bulbs a person.

Run through the calculator (hardneck, saving your own seed, 4 per square foot), that average gives:

HouseholdBulbs a yearCloves to plantSeed garlicSpace
1 person15-1818-210.4-0.5 lb5-6 squares
2 people30-3535-410.8-1.0 lb9-11 squares
4 people60-7070-821.6-1.9 lb18-21 squares, one 4×8 bed

Your own count is better. Sow True Seed starts the same way: are you eating a bulb a day, a week or a month? Count the bulbs your kitchen buys in a month, enter that, and set the unit to month. For two people or a family of four, enter what the whole household uses.

Rows instead of squares

If you plant in rows, set the planting pattern to Rows. University of Georgia Extension spaces cloves 6 inches apart, with rows usually 12 to 14 inches apart. The Penn State Master Gardeners in Allegheny County space cloves 6 to 7 inches apart with 1 foot between rows. Iowa State University Extension goes as close as 3 to 5 inches in the row, with rows 18 to 24 inches apart.

As a check on the pound math: Sow True Seed says a pound of seed garlic plants 20 to 25 feet of row with 6 inches between cloves. The calculator’s 42.5 hardneck cloves at 6 inches fill 21.25 feet of row, inside that range. Softneck runs longer: 67.5 smaller cloves fill about 34 feet, which is why a pound of softneck plants more ground.

Buying and saving seed garlic

  • Buy seed garlic, not grocery garlic. Grocery garlic is often treated so it will not sprout. University of Maryland Extension adds that it may carry disease without symptoms, and Iowa State says it is usually softneck from warmer regions.
  • Pick the type for your winters. Hardneck garlic suits cooler climates, because it needs a freeze to make large bulbs. Softneck suits milder climates, is the type sold in grocery stores, and keeps longer. Wood Prairie sells hardneck varieties for cold climates and softneck for hotter locations.
  • Plant the biggest cloves. Large cloves produce larger bulbs than small cloves (University of Maryland Extension). Break the bulbs apart the day you plant, plant the big cloves and eat the small ones.
  • Save the biggest bulbs. At harvest, set aside your largest bulbs for replanting before you start cooking with the rest. Curing and storage are in Harvesting and Curing Garlic.

When to plant

Garlic is planted in fall and harvested the next summer, and the Plan My Garden planner lists 240 days to maturity. The right fall week depends on where you live, so look up your frost dates by zip code and read When to Plant Garlic on the Plan My Garden blog. Planting depth and mulch for a bed are in How to Plant Garlic in Raised Beds, and bed prep and the whole season are in How to Grow Garlic.

Quick questions

How much garlic should I plant for a family of 4?

Start from the bulbs your household uses. At 1 bulb a week, plant 61 hardneck cloves, about 1.4 pounds of seed garlic, in one 4×4 bed. That includes 9 bulbs to replant. With no count to go on, the U.S. average from Penn State Extension, 2.5 pounds a person, comes to about 60 to 70 bulbs a year for four people. That is 70 to 82 cloves, which fit in one 4×8 bed.

How much garlic do I need to plant for a year?

One clove for each bulb you will use in the year, plus seed for next fall if you save your own. For hardneck at 7 cloves a bulb, add 1 more clove for every 6 bulbs you eat, rounded up. 52 bulbs a year means planting 61 cloves.

How many cloves are in a pound of seed garlic?

About 20 to 65 for hardneck and 45 to 90 for softneck, depending on the variety. Big-cloved hardnecks like Music are about 30. The calculator uses 42.5 for hardneck and 67.5 for softneck.

How many garlic bulbs should I save to replant?

Divide the cloves you want to plant next year by the cloves per bulb and round up. For 61 hardneck cloves at 7 cloves a bulb, keep 9 bulbs, and keep the biggest ones.

How many bulbs does one garlic clove produce?

One. Each clove you plant grows into one full bulb, so a 4×4 bed at 4 cloves per square foot fits up to 64 cloves and gives you up to 64 bulbs.

Let the planner place them

Once you know your clove count, Plan My Garden can lay out the bed. It is free to start: enter your zip code and it finds your frost dates, draw your beds, pick garlic and everything else you want to grow, and it places each plant at square-foot spacing and builds a planting schedule from your frost dates.
