Spring wheat through the year
Against the frost risk in Murmansk
Why these dates
Sow as early as the ground can be worked, roughly three weeks before the last frost. The seedlings tolerate frost easily; what they cannot tolerate is heat during grain fill, so an early sowing is a hedge against a hot midsummer.
Seedlings survive to about -6C. The vulnerable stage is flowering, where a frost causes blank heads that look normal until threshing.
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. Spring wheat are timed for direct sowing 3 weeks before 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 100 to 130 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
