Coriander through the year
Against the frost risk in Sétif
Why these dates
Sow every two weeks from two weeks before last frost. The autumn sowing lasts far longer than any summer one, and in mild climates overwinters.
Takes -5C and grows happily in cool weather. Heat, not frost, is what ends a coriander plant.
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. Coriander are timed for direct sowing 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Sétif.
The median frost-free season here is 250 days, against 45 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
