When can you plant in DuBois, PA?
The last spring frost here typically falls around 05/06, about 251 days from today. The first fall frost typically arrives around 10/14, about 160 frost-free days later.
The USDA Plant Hardiness Zone Map puts DuBois in Zone 6a (-10 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

Why 05/06 isn't a guarantee
05/06 is the middle of 30 years of NOAA records, not a promise. Plant by 04/19 and you're betting against frost in roughly 9 years out of 10. 05/23 is the safer bet, historically only a 1-in-10 chance of frost that late.
