Barley through the year
Against the frost risk in Formosa
Why these dates
Sow in early spring as soon as the ground is workable. Barley ripens two to three weeks ahead of wheat, which makes it the grain of choice where the season is short.
Seedlings tolerate about -8C. The short season means it usually finishes before the first autumn frost even in cold regions.
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. Barley are timed for direct sowing 3 weeks before it, and this page simply resolves those offsets against the frost date computed for Formosa.
The median frost-free season here is 338 days, against 90 to 120 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
