Against the frost risk in Cheboksary
Why these dates
Sow in spring for a harvest that begins after the first autumn frosts. Rushing this crop to maturity in warm weather gives loose, bitter sprouts.
Improves after frost and stands through -12C. This is the clearest example of a crop where the first autumn frost is a target rather than a deadline.
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. Brussels sprouts are timed from 6 weeks before that frost for an indoor start, with planting out 0 weeks after it, and this page simply resolves those offsets against the frost date computed for Cheboksary.
The median frost-free season here is 153 days, against 100 to 130 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
