Broussard, LA: when does the frost end?

Stretching the season past the first frost
With roughly 14 weeks until Broussard's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 02/13 isn't a guarantee
02/13 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/13 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/10 and only about 1 year in 10 sees frost after that.
