When can you plant in Dunsmuir, CA?
Typically, the last spring freeze lands around 06/03, roughly 279 days out. The first fall frost typically arrives around 09/14, about 102 frost-free days later.
The USDA Plant Hardiness Zone Map puts Dunsmuir in Zone 7b (5 to 10°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost
About 2 weeks of growing season left in Dunsmuir before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.
Why 06/03 isn't a guarantee
06/03 is the middle of 30 years of NOAA records, not a promise. Plant by 05/15 and you're betting against frost in roughly 9 years out of 10. 06/19 is the safer bet, historically only a 1-in-10 chance of frost that late.
