Against the frost risk in Santiago de Querétaro
Why these dates
Sow direct two weeks before the last frost and every three weeks after, avoiding high summer. A late-summer sowing crops into autumn.
Tolerates about -6C. The exposed stem is more vulnerable than a buried root would be, so a hard frost damages it directly.
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. Kohlrabi are timed from 5 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Santiago de Querétaro.
The median frost-free season here is 311 days, against 55 to 75 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
