What to do before the first frost
Zone 9a around Myrtle Point has about 10 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 03/28 isn't a guarantee
03/28 is the middle of 30 years of NOAA records, not a promise. Plant by 02/22 and you're betting against frost in roughly 9 years out of 10. 04/27 is the safer bet, historically only a 1-in-10 chance of frost that late.
