When can you plant in Seiling, OK?

Zone 7a

The last spring frost here typically falls around 04/11, about 226 days from today. The first fall frost typically arrives around 10/25, about 194 frost-free days later.

The USDA Plant Hardiness Zone Map puts Seiling in Zone 7a (0 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 8 weeks of growing season left in Seiling before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/11 isn't a guarantee

04/11 is the middle of 30 years of NOAA records, not a promise. Plant by 03/26 and you're betting against frost in roughly 9 years out of 10. 04/26 is the safer bet, historically only a 1-in-10 chance of frost that late.
