Stretching the season past the first frost

Why 03/24 isn't a guarantee
03/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/02 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/17 and only about 1 year in 10 sees frost after that.
