Plant Garlic in Zone 13b
Seed-starting, transplant & harvest dates for USDA Zone 13b
Plant cloves in fall, from about the first frost through the following month, so they root before the ground freezes.
Zone 13b is effectively frost-free, so the Zone 13b calendar for garlic 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 garlic will finish but whether it will sit through the hottest stretch of the year. Garlic is a hardy crop needing about 240 days from sowing to harvest.
Planting garlic 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 garlic here. Sow from about October 1 onward.
Garlic is the definitive fall crop. Plant cloves from around your first frost through the next four weeks: late enough that they root without pushing much top growth, early enough to establish before the ground freezes hard.
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.
