What to do before the first frost
Zone 10a around Lake Helen has about 18 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 02/17 isn't a guarantee
02/17 is the middle of 30 years of NOAA records, not a promise. Plant by 01/14 and you're betting against frost in roughly 9 years out of 10. 03/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
