Runner beans through the year
Against the frost risk in Orël
Why these dates
Two weeks in pots gives a head start and protects seed from mice. Plant out once the supports are up and frost risk has passed.
Frost kills the vine, but runner beans tolerate cool cloudy weather that would stall a French bean. Flowers drop above 30C.
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. Runner beans are timed from 2 weeks before that frost for an indoor start, with planting out 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Orël.
The median frost-free season here is 160 days, against 60 to 80 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
