Conditional — Some Areas
broccoli (zones 2-11) has limited zone overlap with Mississippi (7b-9a). Only zones 7-9 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 Mississippi 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 Mississippi'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 Mississippi's loess and alluvial clay — a soil test confirms it for your site. Drainage matters: this plant wants well (dry spells). If your Mississippi site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

Broccoli in Mississippi — Quick Answer
- Verdict: Conditional — Some Areas
- Plant Zones: 2-11 (USDA PLANTS Database)
- State Zones: 7b-9a (USDA ARS PHZM 2023)
- Growing Season: Feb 28 - Mar 30 to Oct 25 - Nov 20 (NOAA Climate Normals)
- Days to Maturity: 70 days
What Else to Consider
Zone compatibility tells you about winter cold survival — but Mississippi growers also need to think about:
Extreme summer heat and humidity
Heavy alluvial clay in the Delta region
Frequent severe storms and flooding
Pollinator + Wildlife Value
Broccoli draws pollinators (moderate value, USDA PLANTS Database). Planting it near vegetable beds can lift fruit set on neighboring crops.
Mississippi Cooperative Extension
For Mississippi-specific cultivar recommendations, planting calendars, and pest pressure for broccoli, the canonical source is Mississippi State University Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
