Against the frost risk in Changsha
Why these dates
Sow at the last frost date and again every three weeks. Each plant is short-lived, so succession is the only way to keep leaf coming.
Seedlings handle a light frost. Self-seeds freely and often returns without being asked.
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. Dill are timed for direct sowing 0 weeks after it, and this page simply resolves those offsets against the frost date computed for Changsha.
The median frost-free season here is 349 days, against 40 to 60 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
