When can you plant in Endicott, WA?
Around 05/13 is the usual last spring frost, about 258 days away. The first fall frost typically arrives around 09/26, about 133 frost-free days later.
The USDA Plant Hardiness Zone Map puts Endicott in Zone 7a (0 to 5°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

Why 05/13 isn't a guarantee
05/13 is the middle of 30 years of NOAA records, not a promise. Plant by 04/28 and you're betting against frost in roughly 9 years out of 10. 06/01 is the safer bet, historically only a 1-in-10 chance of frost that late.
