What to do before the first frost

About 6 weeks of growing season left in Millbrook before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/04 isn't a guarantee

05/04 is the middle of 30 years of NOAA records, not a promise. Plant by 04/21 and you're betting against frost in roughly 9 years out of 10. 05/21 is the safer bet, historically only a 1-in-10 chance of frost that late.
