🥕 When to Plant Parsnips in Zone 10

Growing parsnips in zone 10

Always use fresh seed — parsnip seed barely survives a year — and be patient with 2–3 week germination. The payoff comes after fall frost converts starch to sugar; they can overwinter in the ground under mulch.

Zone 10 covers south Florida, coastal Southern California, low desert — frost is rare — the calendar flips, with the main garden running fall through spring. Zone dates are medians: frost timing varies within a zone with elevation and terrain, so treat these windows as a solid default and refine them with your own city’s dates below.

Make it local

These windows use zone 10's typical frost dates (last frost ~Jan 25, first frost ~Dec 20). For windows computed from your frost dates, run the ZIP code frost lookup and open the planting calendar — it remembers your city. The seed starting scheduler turns the whole seed rack into one printable, date-sorted list.
