Against the frost risk in Chongqing
Why these dates
Sow from two weeks after the last frost through midsummer for autumn heads. Early sowings bolt, so this is one to hold back rather than rush.
Hardy to about -6C, and blanching heads under a pot also shelters them from the first frosts.
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. Endive are timed from 6 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 Chongqing.
The median frost-free season here is 322 days, against 80 to 100 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
