Grandview, MO 64030 Frost Dates
When can you plant in Grandview, MO?
Around 04/07 is the usual last spring frost, about 222 days away. The first fall frost typically arrives around 10/29, about 202 frost-free days later.
Grandview sits in USDA Zone 6b (-5 to 0°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.
What to do before the first frost

Why 04/07 isn't a guarantee
04/07 is the middle of 30 years of NOAA records, not a promise. Plant by 03/21 and you're betting against frost in roughly 9 years out of 10. 04/24 is the safer bet, historically only a 1-in-10 chance of frost that late.
