Tatsoi through the year
Against the frost risk in Shijiazhuang
Why these dates
Sow from three weeks before the last frost, and again in late summer for the crop that matters. Autumn sowings hold in good condition for weeks.
Hardy to about -8C and often found still green under snow, the low rosette acting as its own insulation.
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. Tatsoi are timed for direct sowing 3 weeks before it, and this page simply resolves those offsets against the frost date computed for Shijiazhuang.
The median frost-free season here is 223 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.
