About 9 weeks of growing season left in Freeport before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/16 isn't a guarantee
04/16 is the middle of 30 years of NOAA records, not a promise. Plant by 03/31 and you're betting against frost in roughly 9 years out of 10. 05/02 is the safer bet, historically only a 1-in-10 chance of frost that late.
