Against the frost risk in Baoding
Why these dates
Sow after the last frost into warm soil. The seed is very fine and should barely be covered.
Killed by the first frost at either end of the season - it has no cold tolerance at all.
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. Amaranth are timed from 4 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Baoding.
The median frost-free season here is 220 days, against 100 to 130 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
