Good King Henry through the year
Against the frost risk in Gustavo Adolfo Madero
Why these dates
Extremely hardy and among the earliest greens available.
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. Good King Henry are timed for direct sowing 3 weeks before it, and this page simply resolves those offsets against the frost date computed for Gustavo Adolfo Madero.
Gustavo Adolfo Madero sits in zone 9b, 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.
Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 2, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
