Plant Lettuce in Zone 13b

Seed-starting, transplant & harvest dates for USDA Zone 13b

Direct sow
Feb 1
Harvest (~50d)
Mar 23

Zone 13b is effectively frost-free, so the Zone 13b calendar for lettuce is set by heat, not cold. There is no last frost to count backward from and no first frost to beat, which means the question is not whether lettuce will finish but whether it will sit through the hottest stretch of the year. Lettuce is a hardy crop needing about 50 days from sowing to harvest.

Planting lettuce for a fall harvest in Zone 13b

Zone 13b has no meaningful frost, so the fall and winter months are the easiest time of year to grow lettuce here. Sow from about October 1 onward.

Lettuce bolts in heat. Fall sowings ripen into cooling weather instead of out of it, which is why fall lettuce is usually the better crop.

Fall dates are counted backward from the Zone 13b average first frost, not forward from a sowing date. See the fall planting calendar by zone for the full method.
