Why these dates

Plant sets six weeks before the last frost, or in autumn in mild-winter regions for an earlier and larger crop. Push them in rather than burying them - the tip should be just visible.

Sets and young growth take -12C easily. Autumn-planted shallots overwinter through most temperate climates without protection.

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. Shallots are timed for direct sowing 6 weeks before it, and this page simply resolves those offsets against the frost date computed for Ciudad Nezahualcoyotl.

The median frost-free season here is 281 days, against 90 to 120 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
