When can you plant in Park Hills, MO?

Zone 6b

Around 04/13 is the usual last spring frost, about 228 days away. The first fall frost typically arrives around 10/21, about 191 frost-free days later.

Zone 6b (-5 to 0°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 Park Hills, not a forecast for this year.

What to do before the first frost

About 8 weeks of growing season left in Park Hills before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

How much risk comes with planting early here

04/13 is the middle of 30 years of NOAA records, not a promise. Plant by 03/28 and you're betting against frost in roughly 9 years out of 10. 04/30 is the safer bet, historically only a 1-in-10 chance of frost that late.
