Muldrow, OK 74948 Frost Dates
When can you plant in Muldrow, OK?
Around 03/25 is the usual last spring frost, about 209 days away. The first fall frost typically arrives around 11/06, about 224 frost-free days later.
The USDA Plant Hardiness Zone Map puts Muldrow in Zone 7b (5 to 10°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 10 weeks of growing season left in Muldrow before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/25 isn't a guarantee
03/25 is the middle of 30 years of NOAA records, not a promise. Plant by 03/04 and you're betting against frost in roughly 9 years out of 10. 04/11 is the safer bet, historically only a 1-in-10 chance of frost that late.
