What to do before the first frost
Zone 11a around Cutler Bay has about 20 weeks left before the first fall frost — that's the usual window to get a cold frame up if you want to keep harvesting past it.
Why 01/18 isn't a guarantee
01/18 is the middle of 30 years of NOAA records, not a promise. Plant by 02/01 and you're betting against frost in roughly 9 years out of 10. 12/31 is the safer bet, historically only a 1-in-10 chance of frost that late.
