Against the frost risk in Formosa
Why these dates
No frost tolerance. Needs 200 or more warm frost-free days, so outside the subtropics it rarely finishes.
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. Taro are timed with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Formosa.
Hardiness is not the obstacle here. Formosa is zone 10a, comfortably inside the range this crop is rated for, so an established plant should come through an average winter without protection.
The median frost-free season here is 338 days, against 200 to 280 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
