Mangetout through the year
Against the frost risk in Tuen Mun
Why these dates
Sow five weeks before the last frost, and again every fortnight until early summer. Autumn sowings in mild climates overwinter for a very early crop.
The plant takes -6C. Flowers and young pods are damaged near -2C, so a late frost costs you the first picking rather than the plant.
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. Mangetout are timed for direct sowing 5 weeks before it, and this page simply resolves those offsets against the frost date computed for Tuen Mun.
