Broad beans through the year
Against the frost risk in Engels
Why these dates
Sow in autumn in zones 7 and warmer for an early summer crop, or eight weeks before last frost in colder regions. Autumn sowings also dodge the worst of blackfly.
Survives -10C once established, and light snow cover helps rather than harms. Very young seedlings going into deep cold are the only real risk.
Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Broad beans are timed for direct sowing 8 weeks before it, and this page simply resolves those offsets against the frost date computed for Engels.
The median frost-free season here is 168 days, against 80 to 100 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
