First, figure out how many bulbs or pounds of garlic you would like to harvest. On average, one pound of seed garlic will plant 20-25 row feet of garlic when planted with 6″ between cloves.
Each pound of hardneck seed garlic has from 35-50 cloves. As each clove grows into its’ own plant and bulb of garlic, each pound will yield 35-50 garlic bulbs (approx 4-7 pounds).
Each pound of softneck garlic seed has from 50-70 cloves, as softnecks have more cloves per bulb than hardnecks. This will yield 50-70 garlic bulbs or approx 6-10 pounds.
