Greenland, AR 72702 Frost Dates
Greenland, AR: when does the frost end?
Around 04/15 is the usual last spring frost, about 230 days away. Fall's first freeze usually shows up around 10/21, roughly 188 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Greenland in Zone 7a (0 to 5°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 8 weeks until Greenland's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
The actual range around Greenland's last frost
04/15 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/31 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/01 and only about 1 year in 10 sees frost after that.
