Against the frost risk in Winston-Salem
Why these dates
No frost tolerance. Killed at 0C.
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. Cumin are timed from 6 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 Winston-Salem.
The median frost-free season here is 216 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.
