About Leek
Leeks are cold-hardy slow-growing vegetables that can be harvested well into autumn and even winter.
Start indoors in late winter — leeks need a very long season. Transplant deeply to blanch stems. Harvest after first frosts — cold improves flavour. Very cold-hardy surviving to -10°C.
Gardening in Oregon
Oregon has dramatically different climates west and east of the Cascades. The Willamette Valley is mild and productive year-round (Zone 8a-8b); eastern Oregon is semi-arid and colder (Zone 5-6).
