What Grows in Macon-Bibb County, Georgia

The last hard freeze (28°F) in Macon-Bibb County typically lands around Feb 24, 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 17.

The first hard freeze (28°F) in Macon-Bibb County typically arrives around Nov 30, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 16, so the watching starts about Oct 31 — about 279 days after the spring freeze cleared.

Measured between 28°F hard freezes, Macon-Bibb County sees about 279 frost-free days — roughly Feb 24 through Nov 30, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 17 to Nov 16, about 244 days.

The federal record around Macon-Bibb County is a meaningful one — 809 documented sites, mostly Underground Storage Tanks entries (606), the nearest Underground Storage Tanks record about 0.4 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.

From about Oct 31 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 Nov 30 (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 Nov 30. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
