Houston, MO 65464 Frost Dates
Houston, MO: when does the frost end?
The last spring frost here typically falls around 04/10, about 225 days from today. Fall's first freeze usually shows up around 10/23, roughly 194 days after the last spring frost.
Houston sits in USDA Zone 7a (0 to 5°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.
Stretching the season past the first frost
With roughly 8 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
04/10 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/25 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.
