Frost risk Sow direct Harvest Today

Why these dates

Sow after midsummer rather than in spring, roughly two weeks after the last frost at the earliest. Shortening days are what make it bulb up instead of run to seed.

Takes about -4C. A cold snap after sowing is itself enough of a check to trigger bolting, which is another argument for the later sowing.

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. Florence fennel are timed for direct sowing 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Ankara.

The median frost-free season here is 185 days, against 80 to 100 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
