Against the frost risk in Newark
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 Newark.
