Against the frost risk in Blida
Why these dates
Sow every ten days from six weeks before last frost. Pause through midsummer, then resume for an autumn crop - late sowings are often the best of the year.
Tolerates -3C and a light frost actually sweetens the leaf. Seed germinates poorly above 25C, which is the more common problem.
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. Lettuce are timed from 6 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 Blida.
