Why these dates

Sow from three weeks before the last frost and every two to three weeks thereafter. It tolerates summer sowings better than most of its relatives.

Hardy to around -8C. Unprotected plants keep growing slowly through mild winters rather than merely surviving them.

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. Komatsuna are timed for direct sowing 3 weeks before it, and this page simply resolves those offsets against the frost date computed for Saltillo.

The median frost-free season here is 297 days, against 35 to 50 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
