Edison, Georgia, sits in USDA hardiness zone 8b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
Reliable performers under these conditions include cabbage, fig, california poppy, and collard greens; what your own ground favors still comes down to its soil, sun, and drainage.
Even in Edison, 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 Edison 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 Edison
Each reading below is measured for Edison itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsEdison runs about 287 days between hard freezes (read from Calhoun County, the closest normal to Edison) — 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
MeasuredEdison 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.
USDA PHZM 2023
The kind of country Edison is in
Edison sits in the Southeastern Plains — EPA Level III, inside the wider Eastern Temperate Forests. That is read at Edison's own centroid rather than borrowed from Calhoun County.

Is it too late to plant in Edison?
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 2 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Edison, Underground Storage Tanks runs higher than the national average — 38 sites within ~10 miles of Edison. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around 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 Edison
Everything above resolves to Edison as a whole — one PHZM band, read across 1K acres, with hard-freeze dates borrowed from Calhoun 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 Edison
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 Calhoun 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 Edison
When does frost risk typically end in Edison?
The last hard freeze (28°F) in Edison 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 Edison?
The first hard freeze (28°F) in Edison typically arrives around Dec 2, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 18, so the watching starts about Nov 2 — about 287 days after the spring freeze cleared.
How long is the growing season in Edison?
Measured between 28°F hard freezes, Edison sees about 287 frost-free days — roughly Feb 18 through Dec 2, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 11 to Nov 18, about 252 days.
Is the soil safe to grow vegetables in Edison?
The federal record around Edison is light — 48 documented sites across the 9 federal source types we checked, mostly Underground Storage Tanks entries (38), the nearest Underground Storage Tanks record about 0.1 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 Edison?
From about Nov 2 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 2 (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 2. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Edison's scale — its 8b band and its 287-day season. Your yard writes its own version of Edison's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
