When can you plant in Lauderdale, MN?
Typically, the last spring freeze lands around 04/23, roughly 238 days out. The first fall frost typically arrives around 10/16, about 175 frost-free days later.
Lauderdale sits in USDA Zone 5a (-20 to -15°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

Why 04/23 isn't a guarantee
04/23 is the middle of 30 years of NOAA records, not a promise. Plant by 04/10 and you're betting against frost in roughly 9 years out of 10. 05/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
