Against the frost risk in Nankana Sahib
Why these dates
Plant two weeks before last frost so shoots emerge around the frost date. Earthing up buries vulnerable shoots and buys you a week of frost protection at a time.
Emerged foliage is blackened at -2C, though the plant usually regrows from the tuber with a yield penalty. Frost after emergence is the classic potato setback.
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. Potatoes are timed for direct sowing 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Nankana Sahib.
