When can you plant in Pagosa Springs, CO?

Zone 5b

The last spring frost here typically falls around 05/23, about 268 days from today. The first fall frost typically arrives around 09/29, about 128 frost-free days later.

Zone 5b (-15 to -10°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 Pagosa Springs, not a forecast for this year.

What to do before the first frost

About 5 weeks of growing season left in Pagosa Springs before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/23 isn't a guarantee

05/23 is the middle of 30 years of NOAA records, not a promise. Plant by 05/09 and you're betting against frost in roughly 9 years out of 10. 06/07 is the safer bet, historically only a 1-in-10 chance of frost that late.
