Ewing, MO 63438 Frost Dates

When can you plant in Ewing, MO?

Zone 6a

Typically, the last spring freeze lands around 04/17, roughly 232 days out. The first fall frost typically arrives around 10/19, about 184 frost-free days later.

Ewing sits in USDA Zone 6a (-10 to -5°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.

What to do before the first frost

About 7 weeks of growing season left in Ewing before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/17 isn't a guarantee

04/17 is the middle of 30 years of NOAA records, not a promise. Plant by 04/03 and you're betting against frost in roughly 9 years out of 10. 05/04 is the safer bet, historically only a 1-in-10 chance of frost that late.
