Brussels Sprouts
Brussels Sprouts is a cool-temperate herbaceous crop that grows best in the 12–20°C range with 900–1600 mm of rain, cropping over a 100–130-day season.
How it grows
Brussels Sprouts forms a single dense head that sits at the ground.
Where Earth's climate suits brussels sprouts
Climatic suitability only — scored for every 0.5° of the planet from this crop's temperature and rainfall tolerances (FAO EcoCrop) on AgroClim 1991–2025 normals (AgERA5 temperature, CHIRPS/ERA5 rainfall). It shows where the rain-fed climate permits the crop, not where it is grown today; irrigation lets many crops thrive in drier country than the map suggests (California, Egypt, the Indus and Nile).

Deep bar = optimal range; pale bar = absolute tolerance. Beyond the pale bar the crop fails. Latitude tolerance ±60° · soil pH 4.5–7.8.
Growing calendar & hazards
An annual cycle of roughly 100–130 days from sowing to harvest, so it is timed to fall within the frost-free, adequately-wet part of the year for the location.
- Hard freeze. Tolerant of chill but killed once temperatures fall below about -5°C.
- Drought. Relatively drought-hardy, but a failed rainy season still cuts yield sharply where irrigation is absent.
- Heat. A cool-season crop that bolts or fails in summer heat; best grown in the shoulder seasons or at altitude.
