Haskell, OK 74436 Frost Dates
When can you plant in Haskell, OK?
Around 04/01 is the usual last spring frost, about 216 days away. The first fall frost typically arrives around 11/01, about 212 frost-free days later.
Zone 7b (5 to 10°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 Haskell, not a forecast for this year.
What to do before the first frost
About 9 weeks of growing season left in Haskell before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
How much risk comes with planting early here
04/01 is the middle of 30 years of NOAA records, not a promise. Plant by 03/12 and you're betting against frost in roughly 9 years out of 10. 04/20 is the safer bet, historically only a 1-in-10 chance of frost that late.
