Cos lettuce through the year
Against the frost risk in Gilgit
Why these dates
Sow every ten days from six weeks before the last frost. The upright habit means it can go closer together than a heading type without rotting in the middle.
Takes about -3C. Outer leaves mark after a frost but the heart is usually untouched and can simply be trimmed to.
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. Cos 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 Gilgit.
The median frost-free season here is 118 days, against 55 to 70 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
