Against the frost risk in Dezhou
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 Dezhou.
Dezhou sits in zone 7b, which is colder than this crop is rated for, so it will need winter protection or a container that can be moved under cover. The dates below still describe the right time of year; the open question is survival rather than timing.
The median frost-free season here is 217 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.
