What to do before the first frost

Zone 7a around Weymouth Town has about 8 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 04/25 isn't a guarantee

04/25 is the middle of 30 years of NOAA records, not a promise. Plant by 04/13 and you're betting against frost in roughly 9 years out of 10. 05/08 is the safer bet, historically only a 1-in-10 chance of frost that late.
