Against the frost risk in Osorno
Why these dates
Sow from three weeks before the last frost and every two to three weeks. Cut at 15cm and it regrows twice before running to its yellow daisy flowers.
Hardy to about -5C. It bolts quickly in long days and heat, so spring and autumn sowings are the productive ones.
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. Shungiku are timed for direct sowing 3 weeks before it, and this page simply resolves those offsets against the frost date computed for Osorno.
The median frost-free season here is 266 days, against 40 to 55 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
