When can you plant in Osceola, MO?
Typically, the last spring freeze lands around 04/16, roughly 231 days out. The first fall frost typically arrives around 10/24, about 189 frost-free days later.
The USDA Plant Hardiness Zone Map puts Osceola in Zone 6b (-5 to 0°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 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. 05/03 is the safer bet, historically only a 1-in-10 chance of frost that late.
