Collards through the year
Against the frost risk in Nizhniy Novgorod
Why these dates
Sow in spring for summer picking or, better, twelve weeks before the first autumn frost for leaves through winter. Pick the lower leaves and the plant keeps rising.
Survives about -10C and sweetens sharply once night temperatures drop below freezing, which is why southern growers treat frost as the start of the season rather than the end.
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. Collards are timed from 6 weeks before that frost for an indoor start, with planting out 2 weeks before 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 55 to 75 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
