Growing parsnips in zone 9
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 9 covers gulf Coast, central Florida, central California, Phoenix and Tucson — summer heat is the limiting factor — many "spring" crops grow best in fall and winter. 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 9's typical frost dates (last frost ~Feb 20, first frost ~Dec 1). 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.
