It is a cool-season vegetable crop. The seeds may be planted as soon as the soil temperature reaches 10 °C, with the plants growing best at temperatures of 13 °C to 18 °C. They do not thrive in the summer heat of warmer temperate and lowland tropical climates, but do grow well in cooler high altitude tropical areas.
