Evans County, in Georgia, sits in USDA hardiness zone 9a — a zone band wide enough that plant choice, not possibility, is the interesting question.
On paper, artichoke, fig, california poppy, and cabbage all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Evans County lies within the Vidalia / South Georgia — a regional growing area with its own character.

Every figure names the dataset it came from. Hard-freeze dates are county 28°F normals: light frosts run a few weeks past them, and tender transplants usually wait 2–3 weeks after the last hard freeze.

Heat and winter chill in Evans County
Across a year, Evans County accumulates about 6,062 growing degree days above 50°F, about 647 more than the middle Georgia county — ahead of 127 of Georgia’s 159 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.
Winter banks about 685 hours below 45°F, 451 fewer than the Georgia middle of 1,136. Chill is what tells a fruit tree its dormancy is over, and it is set by climate rather than by anything you can build.

Soil in Evans County
Across Evans County, the ground is predominantly Ultisols, where Pelham, Tifton, and Fuquay are the most extensive named soil series. The soil is generally well drained with a loamy sand surface. Topsoil pH runs about 4.6–5.5, very strongly acidic. Rainfall drains through hydrologic group B soils.

How the ground varies across Evans County
The USDA soil survey maps 44% of Evans County as well drained — but another 55% drains differently: 39% poorly drained, 8% somewhat poorly drained.
Pelham is the most extensive named soil at 23% of mapped acres, then Tifton (16%) and Fuquay (13%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Evans County
Each reading below is measured for Evans County itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Evans County are well drained, in hydrologic group B — ground that drains quickly.
The upside is soil you can work early in spring and roots that never drown; the cost is that fast-draining ground dries out fast and leaches nutrients away before plants can use them.
Work in compost and mulch to hold moisture and feed, and water more often in short doses than deep and rarely.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Evans County runs about pH 4.6–5.5, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO
Wet ground
MeasuredAbout 40% of Evans County is mapped as hydric — wetland — soil.
If your lot falls in one of those pockets, a standard in-ground bed will fight waterlogging all season, and roots that need air will struggle.
Check how your own ground drains before you dig; raised beds or moisture-loving plantings turn a wet corner from a problem into a niche.
USDA NRCS SSURGO
Season length
MeasuredEvans County runs about 290 days between hard freezes — 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.

The kind of country Evans County is in
Evans County spans 2 EPA Level III ecoregions — Southeastern Plains (77%) and Southern Coastal Plain (23%). Which one your land falls in changes what grows wild there and how the ground behaves, and a county-wide answer cannot tell you which.
What Grows in Evans County
We scored all 1,086 plants against Evans County's own USDA zone 9a and its own 290-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's Georgia profile.
Is it too late to plant in Evans County?
Too late for some crops, right on time for others — a growing season is a sequence, not a deadline. 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. Here the calendar nearly circles: cool-season crops take the winter shift, and the next window is always close.
What gets applied to farmland in Evans County
USGS estimates 8,642 lb of Glyphosate on Evans County farmland in 2019, its largest by weight, ahead of Metolachlor-s (2,580 lb) and Metolachlor & Metolachlor-s (2,580 lb).

What the federal record shows across Evans County — and how to grow with it.
We checked the federal record across Evans County — 86 documented sites across 5 of the 9 source types we track.
The most significant on record: 3 Toxics Release Inventory facilities. Active industrial facilities reporting chemical releases to air, water, and land.
The federal record across Evans County is a modest one — a typical footprint for a growing area. Nothing here calls for alarm; it's worth knowing which recorded sites sit closest to where you grow, and each one on the map carries its type and location. If one turns out to be a near neighbor, a one-time soil test settles the question.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.

What an experienced grower watches for around here
In and around Evans County, Underground Storage Tanks runs higher than the national average — 68 sites across Evans County. That's not a problem with your land — it's information about 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 Evans County
Everything above resolves to Evans County as a whole — one PHZM band and one county frost record, read across 117K acres. 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 county 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 county average.

How we know this about Evans County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Evans County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Evans County
When does frost risk typically end in Evans County?
The last hard freeze (28°F) in Evans County 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.
How long is the growing season in Evans County?
Measured between 28°F hard freezes, Evans County 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 Evans County?
The federal record around Evans County shows 86 documented sites, mostly Underground Storage Tanks entries (68), the nearest Underground Storage Tanks record about 0.7 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.
