Why these dates

Aim to have heads maturing before summer heat or after it. A midsummer maturity date produces small, loose, bitter heads no matter how well you grow the plant.

Transplants take -6C. Purple sprouting types are far hardier and are grown deliberately through winter for a spring crop.

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. Broccoli are timed from 7 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 Santiago de Querétaro.

The median frost-free season here is 311 days, against 60 to 90 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
