Kai-lan through the year
Against the frost risk in Annaba
Why these dates
Sow from two weeks after the last frost and again every three weeks. Cutting the main stem above a leaf brings a second flush of side shoots.
Takes a light frost around -4C. Cold makes the stems sweeter but slows them to a stop, so late sowings need a cloche to finish.
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. Kai-lan are timed for direct sowing 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Annaba.
