Florida planting calendar

When to plant parsnips in Florida — sow, transplant & harvest dates

Florida is mostly USDA zone 9b (range 8a-11b). Dates below are derived from parsnips's frost tolerance and Florida's frost window — not generic national averages.

Parsnips planting timetable for Florida

Stage	When in Florida	Anchor
Direct-sow / set out (main)	October — February	Grown through the cool season, not summer
Shoulder sowing	September and again late February	Avoid germinating into summer heat
First harvest	~110 days after sowing (late autumn through spring)	110-day crop

Dates are state-wide averages for the dominant zone. Local microclimates — elevation, urban heat, coastal moderation — can shift the window by 1-2 weeks. Use the frost-date calculator for a date tuned to your town.

Why Florida's climate shifts the parsnips dates

Florida flips the calendar: its winter is the productive parsnips season while northern states are frozen, and its summer is the off-season. Florida is the warmest state in the contiguous US, with subtropical to tropical conditions. The growing constraint is summer heat, humidity, and rain — not cold.

Parsnips are direct-sown only — their long taproot makes transplanting impractical. Sow direct 2–4 weeks before the last spring frost once soil reaches at least 7 °C; germination is notoriously slow (14–28 days) and patchy below 10 °C, so fresh seed and even moisture are essential. Flavour peaks after the first hard frost (below -2 °C) converts starches to sugars, making autumn and early-winter harvests far sweeter than summer pulls; zones 7–10 can leave roots in the ground through winter for successive harvests.

Frost-risk note

Light frost in the western Panhandle near Tallahassee (zone 8a) only nips the outer leaves — heat, not cold, ends the crop.

Regional variation within Florida

the Florida Keys (zone 11b) can sow earliest in autumn and latest into late winter; the western Panhandle near Tallahassee (zone 8a) has a slightly shorter, frost-bracketed window.

Orlando — USDA zone 10a
Tampa — USDA zone 10a
Jacksonville — USDA zone 9a
Tallahassee — USDA zone 8b

Frequently asked questions

When is the best time to plant parsnips in Florida?

In Florida (mostly USDA zone 9b), grow parsnips as a cool-season crop: direct-sow from October through February, harvest ~110 days later, and skip summer entirely — heat above 24 °C bolts it. Parsnips are cold-hardy — they tolerate frost and actively prefer cool weather, so they go in well before the last spring frost and bolt in summer heat.

What USDA zone is Florida?

Most of Florida sits in USDA hardiness zone 9b, with the state spanning roughly 8a-11b from the western Panhandle near Tallahassee (zone 8a) to the Florida Keys (zone 11b). The last spring frost averages late February (north) to no frost (south) and the first fall frost mid-December (north) to no frost (south).

Can you grow parsnips in Florida?

Yes. Florida's dominant zone 9b supports parsnips — the key is timing. Parsnips are cold-hardy — they tolerate frost and actively prefer cool weather, so they go in well before the last spring frost and bolt in summer heat.

Does the planting date change across Florida?

the Florida Keys (zone 11b) can sow earliest in autumn and latest into late winter; the western Panhandle near Tallahassee (zone 8a) has a slightly shorter, frost-bracketed window.

What else can I plant in Florida around the same time?

The same cool window suits other greens, brassicas, peas, carrots, and radishes — fill beds October through February.
