Greenville, MO: when does the frost end?
Around 04/02 is the usual last spring frost, about 217 days away. Fall's first freeze usually shows up around 11/02, roughly 215 days after the last spring frost.
The USDA Plant Hardiness Zone Map puts Greenville 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

How much risk comes with planting early here
04/02 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/16 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/18 and only about 1 year in 10 sees frost after that.
