Orrick, MO 64077 Frost Dates
When can you plant in Orrick, MO?
Typically, the last spring freeze lands around 04/19, roughly 234 days out. The first fall frost typically arrives around 10/18, about 180 frost-free days later.
The USDA Plant Hardiness Zone Map puts Orrick in Zone 6a (-10 to -5°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 7 weeks of growing season left in Orrick before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/19 isn't a guarantee
04/19 is the middle of 30 years of NOAA records, not a promise. Plant by 04/06 and you're betting against frost in roughly 9 years out of 10. 05/03 is the safer bet, historically only a 1-in-10 chance of frost that late.
