The USDA Plant Hardiness Zone Map puts Magnolia in Zone 8b (15 to 20°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost

Why 03/11 isn't a guarantee
03/11 is the middle of 30 years of NOAA records, not a promise. Plant by 02/17 and you're betting against frost in roughly 9 years out of 10. 04/02 is the safer bet, historically only a 1-in-10 chance of frost that late.
