About Cauliflower
Cauliflower is one of the most rewarding cool-season brassicas — and one of the trickiest. It forms a dense white head that needs steady cool weather and consistent moisture.
Start indoors 6 weeks before last frost; transplant 2-3 weeks before last frost. Blanch heads by tying leaves over them once they're 2-3 inches across. Harvest before curds loosen.
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).
