Against the frost risk in Luoyang
Why these dates
Sow direct eight to ten weeks after the last frost, or better, ten weeks before the first autumn frost. Spring sowings almost always bolt.
Stands to about -8C. In mild climates it holds in the ground all winter.
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. Daikon are timed for direct sowing 8 weeks after it, and this page simply resolves those offsets against the frost date computed for Luoyang.
The median frost-free season here is 239 days, against 60 to 80 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
