When can you plant in Owen, WI?
Typically, the last spring freeze lands around 05/13, roughly 258 days out. The first fall frost typically arrives around 09/26, about 136 frost-free days later.
The USDA Plant Hardiness Zone Map puts Owen in Zone 4b (-25 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 05/13 isn't a guarantee
05/13 is the middle of 30 years of NOAA records, not a promise. Plant by 04/29 and you're betting against frost in roughly 9 years out of 10. 05/29 is the safer bet, historically only a 1-in-10 chance of frost that late.
