Flagler Estates, Florida, sits in USDA hardiness zone 9b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
A short list that earns its place here — okra, meyer lemon, california poppy, and artichoke — with any one site's soil, sun, and drainage making the final cut.
Even in Flagler Estates, no two yards are alike.

What this means for growing in Flagler Estates
Each reading below is measured for Flagler Estates itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsFlagler Estates runs about 329 days between hard freezes (read from St. Johns County, the closest normal to Flagler Estates) — close to year-round growing.
Frost is rarely the limit here; winter plantings are as real as summer ones, and the harder question is which crops shrug off the summer heat.
Grow cool-season crops through the mild winter, and choose heat-tolerant varieties for the summer beds.

Winter hardiness
MeasuredFlagler Estates sits in USDA hardiness zone 9b.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country Flagler Estates is in
Flagler Estates sits in the Southern Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Flagler Estates's own centroid rather than borrowed from St. Johns County.

Is it too late to plant in Flagler Estates?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jan 25 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 20 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

What an experienced grower watches for around here
In and around Flagler Estates, Underground Storage Tanks runs higher than the national average — 78 sites within ~10 miles of Flagler Estates. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Flagler Estates
Everything above resolves to Flagler Estates as a whole — one PHZM band, read across 8K acres, with hard-freeze dates borrowed from St. Johns County’s record because no 30-year normal resolves at this town’s own centroid. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about Flagler Estates
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at St. Johns County’s record, because none resolves here; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Flagler Estates
When does frost risk typically end in Flagler Estates?
The last hard freeze (28°F) in Flagler Estates typically lands around Jan 25, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Feb 15.
When is the first frost in Flagler Estates?
The first hard freeze (28°F) in Flagler Estates typically arrives around Dec 20, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 6, so the watching starts about Nov 20 — about 329 days after the spring freeze cleared.
How long is the growing season in Flagler Estates?
Measured between 28°F hard freezes, Flagler Estates sees about 329 frost-free days — roughly Jan 25 through Dec 20, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 15 to Dec 6, about 294 days.
Is the soil safe to grow vegetables in Flagler Estates?
The federal record around Flagler Estates shows 110 documented sites, mostly Underground Storage Tanks entries (78), the nearest Underground Storage Tanks record about 2.8 miles out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
How do I protect my plants from frost in Flagler Estates?
From about Nov 20 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Dec 20 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Dec 20. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
