Columbus, TX 78951 Frost Dates
When can you plant in Columbus, TX?
Around 03/09 is the usual last spring frost, about 193 days away. The first fall frost typically arrives around 11/20, about 255 frost-free days later.
The USDA Plant Hardiness Zone Map puts Columbus in Zone 9a (20 to 25°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 12 weeks of growing season left in Columbus before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 03/09 isn't a guarantee
03/09 is the middle of 30 years of NOAA records, not a promise. Plant by 02/13 and you're betting against frost in roughly 9 years out of 10. 03/31 is the safer bet, historically only a 1-in-10 chance of frost that late.
