Against the frost risk in Greensboro
Why these dates
Ready in a month. Sow every ten days spring and autumn; skip high summer, when it turns unpleasantly hot and bolts within weeks.
Withstands -7C and holds usable leaf well into winter under cover.
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. Rocket are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Greensboro.
The median frost-free season here is 216 days, against 30 to 45 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
