Why these dates

Sow two weeks after the last frost into soil at 18C or warmer. Sowing into cold soil is the single commonest cause of failure with this crop.

Killed at 0C. Flowers drop rather than set if nights stay above 25C, so extreme heat is as much a problem as cold.

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. Lima beans 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 75 to 95 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
