Chinese cabbages through the year
Against the frost risk in Mexico City
Why these dates
Sow about ten weeks after the last spring frost so the plant heads up as days shorten. Spring sowings run to flower because long days and cold nights together trigger bolting.
Takes a light frost at around -4C once hearted, and the flavour improves for it, but a hard freeze splits the head open.
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. Chinese cabbages are timed for direct sowing 10 weeks after it, and this page simply resolves those offsets against the frost date computed for Mexico City.
The median frost-free season here is 281 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.
