Conditional — Some Areas
broccoli (zones 2-11) has limited zone overlap with Georgia (6b-9a). Only zones 6-9 in the state are suitable.

Growing Season Fit
Zone compatibility says you can survive winter here. Whether the growing season is long enough — and warm enough — is a different question.
Frost-free days
Broccoli wants 60+ frost-free days; a typical Georgia site sees ~220 (NOAA Climate Normals). That leaves comfortable headroom for succession planting.
Growing degree days
Broccoli needs ~1500 GDD (base 50°F) to ripen. The state median runs ~5000 GDD (USDA NRCS county aggregates), so Georgia's typical season clears that easily.
Climate aggregates derive from USDA NRCS county-level hardiness data + Cornell CALS Extension GDD-by-region tables + MSU Extension chill-hours-by-zone (1991-2020 NOAA Climate Normals baseline).
Soil + Drainage Fit
Broccoli likes near-neutral soil (pH 5.5-8.5). That's the common-ground band across Georgia's red clay (piedmont) and sandy loam (coastal plain) — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Georgia site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

Broccoli in Georgia — Quick Answer
- Verdict: Conditional — Some Areas
- Plant Zones: 2-11 (USDA PLANTS Database)
- State Zones: 6b-9a (USDA ARS PHZM 2023)
- Growing Season: Mar 1 - Apr 15 to Oct 15 - Nov 30 (NOAA Climate Normals)
- Days to Maturity: 70 days
What Else to Consider
Zone compatibility tells you about winter cold survival — but Georgia growers also need to think about:
Heavy red Piedmont clay is difficult to work and drains poorly
High humidity drives fungal diseases in summer
Fire ants are a persistent pest in gardens across the state
Summer heat (90-100F) can stress cool-season crops by May
Pollinator + Wildlife Value
Broccoli draws pollinators (moderate value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops.
Georgia Cooperative Extension
For Georgia-specific cultivar recommendations, planting calendars, and pest pressure for broccoli, the canonical source is UGA Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
