Yams through the year
Against the frost risk in Ho Chi Minh City
Why these dates
No frost tolerance whatsoever.
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. Yams are timed with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Ho Chi Minh City.
Ho Chi Minh City sits in zone 13a, which is milder than this crop wants, and a winter that never really arrives is its own problem. The dates below still describe the right time of year; the open question is survival rather than timing.
