What to do before the first frost
Zone 9a around Henderson has about 14 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 02/04 isn't a guarantee
02/04 is the middle of 30 years of NOAA records, not a promise. Plant by 01/10 and you're betting against frost in roughly 9 years out of 10. 02/27 is the safer bet, historically only a 1-in-10 chance of frost that late.
