Houston, AR 72070 Frost Dates
Houston, AR: when does the frost end?
The last spring frost here typically falls around 03/30, about 214 days from today. Fall's first freeze usually shows up around 11/02, roughly 219 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Houston in Zone 8a (10 to 15°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 9 weeks until Houston's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
03/30 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/11 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/15 and only about 1 year in 10 sees frost after that.
