Overview
A sweet, earthy root vegetable that reaches its full potential only after exposure to frost, which converts its starches into sugars. Parsnips were the starchy staple of European cooking before the potato arrived from the Americas, and they remain beloved in British and Northern European cuisine. They require patience — taking 120+ days to mature — but reward with exceptional sweetness and depth of flavor.

Planting Calendar
When to sow, transplant, and harvest by growing zone.
| Zone | Action | Months | Notes |
|---|---|---|---|
| Cold (1-2) | Direct Sow | May — May | Direct sow as soon as soil is workable; use fresh seed only |
| Cold (1-2) | Harvest | Sep — Oct | Harvest after first frost for sweetest flavor; can overwinter in ground |
| Cool (3-4) | Direct Sow | Mar — Apr | Sow early spring; germination is slow (2-4 weeks) |
| Cool (3-4) | Harvest | Sep — Nov | Harvest after frost; mulch heavily to overwinter in ground |
| Moderate (5-7) | Direct Sow | Feb — Apr | Sow early spring; keep soil moist during 2-4 week germination |
| Moderate (5-7) | Harvest | Sep — Dec | Frost sweetens roots; dig as needed through winter |
| Warm (8-9) | Direct Sow | Jan — Feb | Sow in late winter; needs 100-120 days to mature |
| Warm (8-9) | Harvest | May — Jul | Harvest before summer heat; flavor best after cool nights |
| Hot (10+) | Direct Sow | Oct — Dec | Sow in fall for winter harvest; struggles in hot summers |
| Hot (10+) | Harvest | Feb — Apr | Harvest in late winter/early spring |
