Callaway, Florida, sits in USDA hardiness zone 9a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Crops well matched to these conditions include artichoke, fig, california poppy, and cabbage — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in Callaway, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Callaway lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Callaway
Each reading below is measured for Callaway itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsCallaway runs about 312 days between hard freezes (read from Bay County, the closest normal to Callaway) — 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.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredCallaway sits in USDA hardiness zone 9a.
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.
USDA PHZM 2023
The kind of country Callaway is in
Callaway sits in the Southern Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Callaway's own centroid rather than borrowed from Bay County.

Is it too late to plant in Callaway?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Jan 8; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 5 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 14 — 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 Callaway, PFAS runs higher than the national average — 6 sites within ~10 miles of Callaway. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.

Your land is one point inside Callaway
Everything above resolves to Callaway as a whole — one PHZM band, read across 6K acres, with hard-freeze dates borrowed from Bay County’s record because no 30-year normal resolves at this city’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 city 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 Callaway
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Bay 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 city grain anywhere on this page — there is no city-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 Callaway
When does frost risk typically end in Callaway?
The last hard freeze (28°F) in Callaway typically lands around Feb 5, 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 26.
When is the first frost in Callaway?
The first hard freeze (28°F) in Callaway typically arrives around Dec 14, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 30, so the watching starts about Nov 14 — about 312 days after the spring freeze cleared.
How long is the growing season in Callaway?
Measured between 28°F hard freezes, Callaway sees about 312 frost-free days — roughly Feb 5 through Dec 14, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 26 to Nov 30, about 277 days.
Is the soil safe to grow vegetables in Callaway?
The federal record around Callaway is a meaningful one — 651 documented sites, mostly Underground Storage Tanks entries (346), the nearest Underground Storage Tanks record about 1.4 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in Callaway?
From about Nov 14 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 14 (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 14. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Callaway's scale — its 9a band and its 312-day season. Your yard writes its own version of Callaway's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
