Plant broad beans, also called fava beans, directly in the garden 4 to 7 weeks before the last frost in spring. Sow broad beans as soon as the soil can be worked for harvest before the weather warms.
Broad beans are a cool-season crop that grows best in temperatures ranging from 60° to 65°F (15-18°C) but fava beans will grow in temperatures as low as 40°F (4.4°C) and as warm as 75°F (24°C).
Broad beans can withstand light frost. For an extra-early start, sow fava beans 10 to 12 weeks before the last frost and have them ready to set out as soon as the soil can be worked. Young plants in the garden are best protected against heavy frost with row covers or plastic tunnels.
Broad beans require 80 to 100 days to reach harvest. In mild-winter regions sow broad beans in early autumn for winter harvest for a spring harvest.
Broad beans are not recommended as a summer crop where summers are dry and hot.
Broad beans will grow in most soils as long the soil is well-drained. Broad beans prefer a soil pH between 6.0 and 7.5.
Harvest broad beans by picking the lowest pods on the plant first and working up the plant. Broad beans can be used young as snap beans or let beans develop in the pods.
