Against the frost risk in Handan
Why these dates
Plant the whole fruit on its side, sprout end up, two weeks after the last frost. Fruit sets only as days shorten in autumn, so the season has to be long at the far end rather than the near one.
Top growth is killed at 0C. Where winters stay above about -3C the root survives and resprouts, making it effectively perennial in mild climates.
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. Chayotes are timed with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Handan.
The median frost-free season here is 236 days, against 120 to 150 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
