Why these dates

Steady moisture and steady temperature matter more than the exact sowing week. Autumn maturity is easier to achieve than spring in most climates.

Tolerates light frost but the curd itself is damaged below about -3C. Fold leaves over developing heads when frost threatens.

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. Cauliflowers 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 Longling County.

The median frost-free season here is 337 days, against 65 to 95 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
