Auburn, KS 66546 Frost Dates
When can you plant in Auburn, KS?
Typically, the last spring freeze lands around 04/15, roughly 230 days out. The first fall frost typically arrives around 10/21, about 185 frost-free days later.
Zone 6b (-5 to 0°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Auburn, not a forecast for this year.
What to do before the first frost
About 8 weeks of growing season left in Auburn before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/15 isn't a guarantee
04/15 is the middle of 30 years of NOAA records, not a promise. Plant by 04/02 and you're betting against frost in roughly 9 years out of 10. 04/30 is the safer bet, historically only a 1-in-10 chance of frost that late.
