Dodge County, in Georgia, sits in USDA hardiness zone 8b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
The conditions favor cabbage, fig, california poppy, and collard greens, among others — though every individual site edits that list with its own soil, sun, and drainage.
Dodge County lies within the Vidalia / South Georgia — a regional growing area with its own character.

Heat and winter chill in Dodge County
Across a year, Dodge County accumulates about 5,774 growing degree days above 50°F, about 359 more than the middle Georgia county — ahead of 106 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 871 hours below 45°F, 265 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 Dodge County
Across Dodge County, the ground is predominantly Ultisols, where Tifton, Fuquay, and Nankin are the most extensive named soil series. The soil is generally well drained with a loamy sand surface. Topsoil pH runs about 5.2–5.5, strongly acidic. Rainfall drains through hydrologic group B soils.

How the ground varies across Dodge County
The USDA soil survey maps 70% of Dodge County as well drained — but another 28% drains differently: 22% poorly drained, 4% somewhat poorly drained.
Tifton is the most extensive named soil at 16% of mapped acres, then Fuquay (13%) and Nankin (11%).
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 Dodge County
Each reading below is measured for Dodge 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 Dodge 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 Dodge County runs about pH 5.2–5.5, 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 25% of Dodge 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
MeasuredDodge County runs about 292 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.

What Grows in Dodge County
We scored all 1,086 plants against Dodge County's own USDA zone 8b and its own 292-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 Dodge 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 20; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 17 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 6 — 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 gets applied to farmland in Dodge County
USGS estimates 27,253 lb of Glyphosate on Dodge County farmland in 2019, its largest by weight, ahead of Acetochlor (21,024 lb) and Fluometuron (20,528 lb).

What the federal record shows across Dodge County — and how to grow with it.
We checked the federal record across Dodge County — 128 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 Dodge 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.

What an experienced grower watches for around here
In and around Dodge County, Underground Storage Tanks runs higher than the national average — 97 sites across Dodge County. 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 Dodge County
Everything above resolves to Dodge County as a whole — one PHZM band and one county frost record, read across 317K 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 Dodge 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 Dodge County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Dodge County
When does frost risk typically end in Dodge County?
The last hard freeze (28°F) in Dodge County typically lands around Feb 17, 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 10.
How long is the growing season in Dodge County?
Measured between 28°F hard freezes, Dodge County sees about 292 frost-free days — roughly Feb 17 through Dec 6, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 10 to Nov 22, about 257 days.
Is the soil safe to grow vegetables in Dodge County?
The federal record around Dodge County is a meaningful one — 128 documented sites, mostly Underground Storage Tanks entries (97), the nearest Underground Storage Tanks record about 0.8 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.
