What to do before the first frost
About 9 weeks of growing season left in Murray before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/05 isn't a guarantee
04/05 is the middle of 30 years of NOAA records, not a promise. Plant by 03/19 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.
