Milan, NM 87045 Frost Dates
When can you plant in Milan, NM?
Typically, the last spring freeze lands around 05/29, roughly 274 days out. The first fall frost typically arrives around 09/26, about 118 frost-free days later.
The USDA Plant Hardiness Zone Map puts Milan in Zone 6a (-10 to -5°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

About 4 weeks of growing season left in Milan before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 05/29 isn't a guarantee
05/29 is the middle of 30 years of NOAA records, not a promise. Plant by 05/11 and you're betting against frost in roughly 9 years out of 10. 06/12 is the safer bet, historically only a 1-in-10 chance of frost that late.
