Against the frost risk in Xiamen
Why these dates
Sow two weeks after the last frost. For drying, count back at least a hundred frost-free days; for fresh shelling, twenty fewer will do.
Killed at 0C. Pods left to dry need a spell of dry weather before the first frost, which is the usual limit on growing them in a damp climate.
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. Borlotti beans are timed for direct sowing 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Xiamen.
