Sweet potatoes through the year
Against the frost risk in Luxor
Why these dates
Plant slips three weeks after last frost into soil at 18C or above. In cool climates, black plastic mulch is the difference between a crop and a disappointment.
Damaged at 1C - even a near-frost harms the roots. Lift before the first frost, not after 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. Sweet potatoes are timed with planting out 3 weeks after it, and this page simply resolves those offsets against the frost date computed for Luxor.
