Buckwheat through the year
Against the frost risk in Nizhniy Novgorod
Why these dates
Sow after the last frost, any time up to about eleven weeks before the first. Because it matures so fast it can follow an early crop and still finish, and it smothers weeds while doing so.
Killed outright by the lightest frost, which is exactly why it works as a summer cover crop that clears itself away in autumn.
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. Buckwheat are timed for direct sowing 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Nizhniy Novgorod.
The median frost-free season here is 155 days, against 70 to 90 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
