Red Level, AL: when does the frost end?
Around 03/25 is the usual last spring frost, about 209 days away. Fall's first freeze usually shows up around 11/09, roughly 230 days after the last spring frost.

With roughly 10 weeks until Red Level's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
03/25 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/28 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/14 and only about 1 year in 10 sees frost after that.
