Quinoa through the year
Against the frost risk in Cần Thơ
Why these dates
Sow direct around the last frost date. Quinoa needs a long season but dislikes hot nights during flowering, which makes a cool upland summer ideal and a hot humid one poor.
Young plants tolerate about -3C, and the mature crop takes light frost while drying down, which is useful at the end of a short season.
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. Quinoa are timed for direct sowing 1 weeks before it, and this page simply resolves those offsets against the frost date computed for Cần Thơ.
