Against the frost risk in Annaba
Why these dates
Sow direct four weeks before the last frost into cool soil, or start indoors eight weeks before it. Germination is slow and uneven at the best of times and much better after a fortnight of cold, so autumn sowing suits it. Self-seeds where the drainage is good enough.
Hardy to about -12C. Autumn sowing is the traditional method around the Mediterranean and works anywhere in zone 8 and milder. Humid summer heat brings it to an early end.
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. Orlayas are timed from 8 weeks before that frost for an indoor start, with planting out 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Annaba.
Annaba sits in zone 11a, which is milder than this crop wants, and a winter that never really arrives is its own problem. The dates below still describe the right time of year; the open question is survival rather than timing.
