Savoy cabbages through the year
Against the frost risk in Ziyang
Why these dates
Sown in late spring and planted out by midsummer, savoys mature from mid-autumn and can then be cut as needed for months rather than harvested all at once.
Reliably hardy to about -12C and improved by frost, which is why savoy is the type to grow if your winter has teeth.
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. Savoy cabbages are timed from 8 weeks before that frost for an indoor start, with planting out 3 weeks before it, and this page simply resolves those offsets against the frost date computed for Ziyang.
The median frost-free season here is 313 days, against 90 to 130 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
