When can you plant in Burns Flat, OK?

Zone 7b

The last spring frost here typically falls around 04/05, about 220 days from today. The first fall frost typically arrives around 11/04, about 210 frost-free days later.

The USDA Plant Hardiness Zone Map puts Burns Flat 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 Burns Flat before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/05 isn't a guarantee

04/05 is the middle of 30 years of NOAA records, not a promise. Plant by 03/19 and you're betting against frost in roughly 9 years out of 10. 04/22 is the safer bet, historically only a 1-in-10 chance of frost that late.
