Steele, MO: when does the frost end?
Around 03/24 is the usual last spring frost, about 208 days away. Fall's first freeze usually shows up around 11/06, roughly 227 days after the last spring frost.
Zone 8a (10 to 15°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Steele, not a forecast for this year.
Stretching the season past the first frost
With roughly 10 weeks until Steele'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
03/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/05 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/10 and only about 1 year in 10 sees frost after that.
