Plant Basil in Zone 13a
Seed-starting, transplant & harvest dates for USDA Zone 13a
Zone 13a is effectively frost-free, so the Zone 13a calendar for basil 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 basil will finish but whether it will sit through the hottest stretch of the year. Basil is a tender crop needing about 60 days from sowing to harvest.
