When can you plant in Salem, OR?

Zone 8b

The last spring frost here typically falls around 04/03, about 218 days from today. The first fall frost typically arrives around 11/01, about 212 frost-free days later.

Zone 8b (15 to 20°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 Salem, not a forecast for this year.

What to do before the first frost

About 9 weeks of growing season left in Salem 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

04/03 is the middle of 30 years of NOAA records, not a promise. Plant by 03/10 and you're betting against frost in roughly 9 years out of 10. 04/27 is the safer bet, historically only a 1-in-10 chance of frost that late.
