Against the frost risk in Murmansk
Why these dates
Sow two weeks after the last frost. Pods on a plant fill almost simultaneously, so the harvest window is about a week and succession sowing is the only way to extend it.
Killed at 0C. Flowering is triggered by day length, so a variety chosen for the wrong latitude flowers at the wrong time regardless of sowing date.
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. Edamame are timed for direct sowing 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Murmansk.
The median frost-free season here is 113 days, against 75 to 95 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
