Morris, NY 13808 Frost Dates
Morris, NY: when does the frost end?
The last spring frost here typically falls around 05/17, about 262 days from today. Fall's first freeze usually shows up around 10/03, roughly 141 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Morris in Zone 5b (-15 to -10°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
Stretching the season past the first frost
With roughly 5 weeks until Morris's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/17 isn't a guarantee
05/17 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/30 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/30 and only about 1 year in 10 sees frost after that.
