Why these dates

Sow a short row every two weeks from one week after last frost until ten weeks before first frost. Beans crop heavily for a fortnight then decline, so succession matters more than quantity.

Beans are killed by the lightest frost at any stage. They also germinate poorly below 15C, so patience in spring pays.

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. Green beans are timed for direct sowing 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Xuancheng.

The median frost-free season here is 262 days, against 50 to 60 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
