When can you plant in East Lansing, MI?

Zone 6a

The USDA Plant Hardiness Zone Map puts East Lansing in Zone 6a (-10 to -5°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

05/01 is the middle of 30 years of NOAA records, not a promise. Plant by 04/18 and you're betting against frost in roughly 9 years out of 10. 05/18 is the safer bet, historically only a 1-in-10 chance of frost that late.
