When can you plant in Fleischmanns, NY?
Around 05/18 is the usual last spring frost, about 263 days away. The first fall frost typically arrives around 10/02, about 137 frost-free days later.
The USDA Plant Hardiness Zone Map puts Fleischmanns in Zone 5b (-15 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

Why 05/18 isn't a guarantee
05/18 is the middle of 30 years of NOAA records, not a promise. Plant by 05/01 and you're betting against frost in roughly 9 years out of 10. 06/01 is the safer bet, historically only a 1-in-10 chance of frost that late.
