Why these dates

Sow from two weeks after the last frost and again every three weeks. Cutting the main stem above a leaf brings a second flush of side shoots.

Takes a light frost around -4C. Cold makes the stems sweeter but slows them to a stop, so late sowings need a cloche to finish.

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. Kai-lan are timed for direct sowing 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Puebla.

The median frost-free season here is 311 days, against 50 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
