Against the frost risk in Zhenjiang
Why these dates
Autumn crops sown eight to ten weeks before first frost are sweeter and less prone to woodiness than anything grown into summer heat.
Tolerates -8C. Roots hold in the ground well past 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. Turnips are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Zhenjiang.
The median frost-free season here is 252 days, against 40 to 55 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
