Against the frost risk in Zaoyang
Why these dates
Sow or plant out three weeks after the last frost, once soil is at 18C. Soaking the hard seed overnight noticeably improves germination.
Killed at 0C and checked below 15C, at which point the plant stops setting pods and sulks until warmth returns.
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. Okra are timed from 4 weeks before that frost for an indoor start, with planting out 3 weeks after it, and this page simply resolves those offsets against the frost date computed for Zaoyang.
The median frost-free season here is 262 days, against 55 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
