Against the frost risk in Jersey City
Why these dates
The autumn sowing is the dependable one. Spring sowings bolt readily unless made very early or grown under cover.
Handles a few degrees of frost. A hard freeze destroys the succulent midribs.
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. Pak choi are timed from 4 weeks before that frost for an indoor start, with planting out 1 weeks before it, and this page simply resolves those offsets against the frost date computed for Jersey City.
The median frost-free season here is 209 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.
