Rush Hill, MO 65280 Frost Dates
Rush Hill, MO: when does the frost end?
Around 04/11 is the usual last spring frost, about 226 days away. Fall's first freeze usually shows up around 10/25, roughly 197 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Rush Hill in Zone 6b (-5 to 0°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 Rush Hill's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/11 isn't a guarantee
04/11 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/27 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/26 and only about 1 year in 10 sees frost after that.
