Barrow County, in Georgia, sits in USDA hardiness zone 8b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
These conditions suit cabbage, fig, california poppy, and collard greens — a starting list any specific site will trim or extend with its own soil, sun, and drainage.
Barrow County lies within the Piedmont — a regional growing area with its own character.

Heat and winter chill in Barrow County
Across a year, Barrow County accumulates about 4,681 growing degree days above 50°F, about 734 fewer than the middle Georgia county — ahead of 33 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 1,515 hours below 45°F, 379 more 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 Barrow County
Across Barrow County, the ground is predominantly Ultisols, where Cecil, Pacolet, and Appling are the most extensive named soil series. The soil is generally well drained with a sandy loam surface. Topsoil pH runs about 5.5, strongly acidic. Rainfall drains through hydrologic group B soils.

How the ground varies across Barrow County
The USDA soil survey maps 91% of Barrow County as well drained — but another 8% drains differently: 5% somewhat poorly drained, 2% moderately well drained.
Cecil is the most extensive named soil at 37% of mapped acres, then Pacolet (18%) and Appling (14%).
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 Barrow County
Each reading below is measured for Barrow 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 Barrow 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 Barrow County runs about pH 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
Season length
MeasuredBarrow County runs about 268 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.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredBarrow County sits in USDA hardiness zone 8b.
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 Barrow County is in
Barrow County sits in the Piedmont — EPA Level III, inside the wider Eastern Temperate Forests. One consistent ecological setting across the whole county.
What Grows in Barrow County
We scored all 1,086 plants against Barrow County's own USDA zone 8b and its own 268-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 Barrow County?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Feb 4; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 4 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 27 — 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 the federal record shows across Barrow County — and how to grow with it.
We checked the federal record across Barrow County — 207 documented sites across 6 of the 9 source types we track.
The most significant on record: 2 Superfund sites (none NPL-listed). Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
There's a meaningful federal record across Barrow County — worth a look before you plant food, not a reason to hold back from growing. Proximity to a documented site is information, not a diagnosis of any one yard. A soil test before new food beds is the sensible precaution here, and the map shows exactly which sites sit where, so you can see what's actually near you.
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 Barrow County, two things run higher than the national average across Barrow County — PFAS (5 sites) and Underground Storage Tanks (150 sites). 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.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Barrow County
Everything above resolves to Barrow County as a whole — one PHZM band and one county frost record, read across 103K 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 Barrow 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 Barrow County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Barrow County
When does frost risk typically end in Barrow County?
The last hard freeze (28°F) in Barrow County typically lands around Mar 4, 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 25.
How long is the growing season in Barrow County?
Measured between 28°F hard freezes, Barrow County sees about 268 frost-free days — roughly Mar 4 through Nov 27, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 25 to Nov 13, about 233 days.
Is the soil safe to grow vegetables in Barrow County?
The federal record around Barrow County is a meaningful one — 207 documented sites, mostly Underground Storage Tanks entries (150), the nearest Underground Storage Tanks record about 0.2 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.
