Hagan, Georgia, sits in USDA hardiness zone 9a — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
These conditions suit artichoke, fig, california poppy, and cabbage — a starting list any specific site will trim or extend with its own soil, sun, and drainage.

What this means for growing in Hagan
Each reading below is measured for Hagan itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsHagan runs about 290 days between hard freezes (read from Evans County, the closest normal to Hagan) — 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
MeasuredHagan 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.

The kind of country Hagan is in
Hagan sits in the Southeastern Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Hagan's own centroid rather than borrowed from Evans County.

Is it too late to plant in Hagan?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Jan 21; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 18 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 5 — long-season crops need about 90 days of runway, quick greens only 30. And with a calendar this mild, the honest answer is that planting barely stops — winter opens seasons colder regions never see.

What an experienced grower watches for around here
In and around Hagan, Underground Storage Tanks runs higher than the national average — 71 sites within ~10 miles of Hagan. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
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 Hagan
Everything above resolves to Hagan as a whole — one PHZM band, read across 1K acres, with hard-freeze dates borrowed from Evans 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 Hagan
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 Evans 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 Hagan
When does frost risk typically end in Hagan?
The last hard freeze (28°F) in Hagan typically lands around Feb 18, 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 Mar 11.
When is the first frost in Hagan?
The first hard freeze (28°F) in Hagan typically arrives around Dec 5, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 21, so the watching starts about Nov 5 — about 290 days after the spring freeze cleared.
How long is the growing season in Hagan?
Measured between 28°F hard freezes, Hagan sees about 290 frost-free days — roughly Feb 18 through Dec 5, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 11 to Nov 21, about 255 days.
Is the soil safe to grow vegetables in Hagan?
The federal record around Hagan shows 89 documented sites, mostly Underground Storage Tanks entries (71), the nearest Underground Storage Tanks record about 0.4 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 Hagan?
From about Nov 5 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 5 (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 5. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Hagan's scale — its 9a band and its 290-day season. Your yard writes its own version of Hagan's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
