When can you plant in Colorado Springs, CO?

Zone 6a

Around 05/03 is the usual last spring frost, about 248 days away. The first fall frost typically arrives around 10/08, about 158 frost-free days later.

Zone 6a (-10 to -5°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 Colorado Springs, not a forecast for this year.

About 6 weeks of growing season left in Colorado Springs 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

05/03 is the middle of 30 years of NOAA records, not a promise. Plant by 04/22 and you're betting against frost in roughly 9 years out of 10. 05/15 is the safer bet, historically only a 1-in-10 chance of frost that late.
