Denton, Georgia, sits in USDA hardiness zone 9a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Well-matched crops include artichoke, fig, california poppy, and cabbage, and the gap between "grows in the area" and "grows in your yard" is closed by soil, sun, and drainage.
Even in Denton, 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 Denton 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 Denton
Each reading below is measured for Denton itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsDenton runs about 290 days between hard freezes (read from Jeff Davis County, the closest normal to Denton) — 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
MeasuredDenton 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 Denton is in
Denton sits in the Southern Coastal Plain — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Denton's own centroid rather than borrowed from Jeff Davis County.

Is it too late to plant in Denton?
For most of the year, no — what changes is which crops still fit the days remaining. 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 4 — long-season crops need about 90 days of runway, quick greens only 30. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.

Your land is one point inside Denton
Everything above resolves to Denton as a whole — one PHZM band, read across 973 acres, with hard-freeze dates borrowed from Jeff Davis 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 Denton
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 Jeff Davis 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 Denton
When does frost risk typically end in Denton?
The last hard freeze (28°F) in Denton 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.
When is the first frost in Denton?
The first hard freeze (28°F) in Denton typically arrives around Dec 4, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 20, so the watching starts about Nov 4 — about 290 days after the spring freeze cleared.
How long is the growing season in Denton?
Measured between 28°F hard freezes, Denton sees about 290 frost-free days — roughly Feb 17 through Dec 4, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 10 to Nov 20, about 255 days.
Is the soil safe to grow vegetables in Denton?
The federal record around Denton is light — 23 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (16), the nearest Underground Storage Tanks record about 0.4 miles out — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.
How do I protect my plants from frost in Denton?
From about Nov 4 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 4 (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 4. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Denton's scale — its 9a band and its 290-day season. Your yard writes its own version of Denton's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
