What these dates mean in Central Oregon
Start indoors usually runs about 31 days, from Mar 1 to Mar 31.
Frost-date caveat: these are published ranges for Central Oregon. A northern or high-elevation site will run later than a southern or low one, and a cold wet spring can push planting past the window. Monthly advice is not applicable to all areas of Oregon; frost dates and local conditions vary. Check your last spring frost and soil temperature, and confirm with your county extension office.
