Against the frost risk in Karachi
Why these dates
Sow direct about ten weeks after the last frost, aiming to mature into cool autumn weather. Thin ruthlessly - crowded swedes stay small.
Very hardy, taking -10C in the ground, and sweeter after frost. Can be left in the soil and lifted through winter in most climates.
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. Swedes are timed for direct sowing 10 weeks after it, and this page simply resolves those offsets against the frost date computed for Karachi.
