When can you plant in Kaukauna, WI?

Zone 5b

Typically, the last spring freeze lands around 05/04, roughly 249 days out. The first fall frost typically arrives around 10/06, about 154 frost-free days later.

The USDA Plant Hardiness Zone Map puts Kaukauna in Zone 5b (-15 to -10°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

About 6 weeks of growing season left in Kaukauna before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

How much risk comes with planting early here

05/04 is the middle of 30 years of NOAA records, not a promise. Plant by 04/21 and you're betting against frost in roughly 9 years out of 10. 05/20 is the safer bet, historically only a 1-in-10 chance of frost that late.
