Why these dates

Sow from three weeks before the last frost for spring greens, then again ten weeks before the first autumn frost for the milder, larger autumn crop.

Takes about -6C. A frost before picking noticeably softens the heat, which is why autumn mustard is the sweeter 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. Mustard greens are timed for direct sowing 3 weeks before 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 40 to 60 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
