Courgettes through the year
Against the frost risk in Daegu
Why these dates
Two plants feed most households. A single sowing two weeks after last frost is usually enough; a July sowing gives cleaner, mildew-free fruit in long-season climates.
One light frost ends the plant. Because it crops so quickly, a courgette sown after all frost risk has passed still produces for months.
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. Courgettes are timed from 3 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 Daegu.
The median frost-free season here is 201 days, against 45 to 60 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
