What to do before the first frost
Zone 9a around Nixon has about 12 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 03/07 isn't a guarantee
03/07 is the middle of 30 years of NOAA records, not a promise. Plant by 02/09 and you're betting against frost in roughly 9 years out of 10. 03/30 is the safer bet, historically only a 1-in-10 chance of frost that late.
