When can you plant in Grafton, NE?

Zone 6a

The last spring frost here typically falls around 04/25, about 240 days from today. The first fall frost typically arrives around 10/14, about 170 frost-free days later.

Grafton sits in USDA Zone 6a (-10 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 7 weeks of growing season left in Grafton before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 04/25 isn't a guarantee

04/25 is the middle of 30 years of NOAA records, not a promise. Plant by 04/10 and you're betting against frost in roughly 9 years out of 10. 05/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
