When can you plant in Creve Coeur, MO?
Around 04/04 is the usual last spring frost, about 219 days away. The first fall frost typically arrives around 10/29, about 206 frost-free days later.
Creve Coeur 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.
What to do before the first frost
About 9 weeks of growing season left in Creve Coeur before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 04/04 isn't a guarantee
04/04 is the middle of 30 years of NOAA records, not a promise. Plant by 03/20 and you're betting against frost in roughly 9 years out of 10. 04/21 is the safer bet, historically only a 1-in-10 chance of frost that late.
