§ 040 · Questions
On average from about February 25 in Portland to June 1 in Bend. Frost is over 9 years in 10 by April 21 to July 8.
The extension service lists May to June. Tomatoes are frost-tender, so Ezina dates them from about March 25 in Portland. If frost is in the forecast, wait until it passes.
The extension calendar lists artichokes, garlic, radishes, spinach for October.
The latest fall windows on the calendar close in November. Filter by Fall above to see what is still open.
A zone is the coldest winter night, not a frost date. These dates come from NOAA station records and the extension service.
