Against the frost risk in Dengzhou
Why these dates
Killed by the first frost.
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. Summer savory are timed from 6 weeks before that frost for an indoor start, with planting out 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Dengzhou.
The median frost-free season here is 260 days, against 60 to 75 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
