When can you plant in Crouch, ID?

Zone 7a

The last spring frost here typically falls around 05/31, about 276 days from today. The first fall frost typically arrives around 09/16, about 108 frost-free days later.

Crouch sits in USDA Zone 7a (0 to 5°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

What to do before the first frost

About 3 weeks of growing season left in Crouch before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/31 isn't a guarantee

05/31 is the middle of 30 years of NOAA records, not a promise. Plant by 05/08 and you're betting against frost in roughly 9 years out of 10. 06/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
