Why these dates

Sow from four weeks before the last frost and every two weeks after. A late-summer sowing under cover picks through most of the winter.

Hardy to about -8C unprotected and considerably lower under a cloche, which makes it one of the most useful winter salad leaves.

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. Mizuna are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Istanbul.

The median frost-free season here is 303 days, against 35 to 45 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
