What these dates mean in Oregon Coast
Planting usually runs about 30 days, from Apr 1 to Apr 30.
Frost-date caveat: these are published ranges for Oregon Coast. 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.
