Why these dates

Sow thickly every week from four weeks before the last frost. It needs no space, no depth and no waiting, so it fills the edges of beds all season.

Damaged below about -3C, but the crop is over so quickly that frost rarely gets the chance to reach it.

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. Cress are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Cần Thơ.
