Growing Parsley Root (Hamburg Parsley): A Complete Profile
By Growing Home Greens Team · August 10, 2026

Parsley root, also called Hamburg parsley, is grown for its long, white, parsnip-like root rather than its leaves, though the foliage is edible too and tastes just like standard parsley.
Patience during germination
Direct-seed only, sown in early to midspring after frost danger passes, a quarter to a half inch deep, 1 to 2 seeds per inch in rows or bands 12 to 18 inches apart. Germination takes a long time, 14 to 30 days, so keep the seedbed consistently moist and don’t assume a bare bed after two weeks means the sowing failed. Thin to 1 to 3 inches apart depending on the root size wanted.
Cold-hardy in the ground
This plant handles cold well and can withstand some freezing while still in the field, making it a reasonable crop to leave in the ground into the colder part of the season rather than rushing the harvest.
Harvest and storage
Loosen the soil with a spading fork and lift roots once they’ve reached the desired size. Trim the tops and store at 32°F and 95 percent relative humidity, the same conditions as other winter storage roots.
Parsley root has no well-established companion pairings, and nothing it needs to be kept away from. At 9 plants per square foot, it fits well in a root-crop row in the Garden Designer, planned alongside carrots and parsnips that share similar germination patience.
