When can you plant in Coon Rapids, MN?

Zone 5a

Around 05/05 is the usual last spring frost, about 250 days away. The first fall frost typically arrives around 10/02, about 148 frost-free days later.

The USDA Plant Hardiness Zone Map puts Coon Rapids in Zone 5a (-20 to -15°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

How much risk comes with planting early here

05/05 is the middle of 30 years of NOAA records, not a promise. Plant by 04/23 and you're betting against frost in roughly 9 years out of 10. 05/21 is the safer bet, historically only a 1-in-10 chance of frost that late.
