Why these dates

Sow alongside mizuna from four weeks before the last frost. It stands longer before bolting, so it suits the sowings that get left unpicked.

Hardy to roughly -8C. Frost tightens the flavour rather than damaging the leaf.

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. Mibuna are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Tongchuanshi.

The median frost-free season here is 226 days, against 40 to 50 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
