Against the frost risk in La Pintana
Why these dates
Sow every week in spring and autumn. Summer sowings turn woody and hot - stop when daytime temperatures pass 25C and resume in late summer.
Handles -6C easily and is often the first and last thing harvested in the year.
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. Radishes are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for La Pintana.
The median frost-free season here is 265 days, against 22 to 30 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
