Why these dates

Sow around the last frost date and lift from autumn onwards, once the root has had a full season to extend. Roots left in the ground keep perfectly well over winter.

The root is hardy to -8C and below, so lifting can be spread across the whole winter rather than done all at once.

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. Burdock are timed for direct sowing 0 weeks after it, and this page simply resolves those offsets against the frost date computed for Kansas City.

The median frost-free season here is 195 days, against 100 to 140 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
