Which zones grow Red Sails best?

Red Sails is a lettuce variety rated for zone 3 and warmer (frost-free). In colder zones, start seeds indoors earlier and use a longer-season plan; in very hot zones (9+), pick the cooler fall window. The ZIP tool below gives the exact answer for your neighborhood.

Cool edge (zone 3)
Start indoors ~8 weeks before last frost; transplant after soil warms; expect a shorter, later harvest.
Sweet spot (zone 68)
Full season; sow per the calendar and harvest at the catalog 45-day target.
Hot edge (zone 10+)
Heat may slow fruiting — favor early planting or a fall crop; shade in peak summer.
