Celtuce through the year
Against the frost risk in Casablanca
Why these dates
Sow from two weeks before the last frost. Unlike a leaf lettuce you want this one to run up, so bolting weather is working in your favour.
Takes about -3C, the same as any lettuce, and the stem is no hardier than the leaf.
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. Celtuce 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 Casablanca.
