What to do before the first frost
Zone 3b around Nome has about 1 week 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 06/05 isn't a guarantee
06/05 is the middle of 30 years of NOAA records, not a promise. Plant by 05/20 and you're betting against frost in roughly 9 years out of 10. 06/26 is the safer bet, historically only a 1-in-10 chance of frost that late.
