What to do before the first frost

Zone 7b around Moore has about 9 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 04/04 isn't a guarantee

04/04 is the middle of 30 years of NOAA records, not a promise. Plant by 03/16 and you're betting against frost in roughly 9 years out of 10. 04/20 is the safer bet, historically only a 1-in-10 chance of frost that late.
