When to Plant Cabbage in Oregon

A satisfying crop that stores well. Plant in spring or fall for crisp, dense heads.

Growing Cabbage in Oregon

Cabbage in Oregon's Climate

Cabbage is a cool-season crop in warm climates. Transplant from September through November for fall-winter harvest. Your mild winters produce tender, sweet heads. Frost-sweetened cabbage is noticeably better tasting. Choose heat-tolerant varieties for the warmer edges of your cool window.

Soil Considerations for Oregon

Rich volcanic soils in Willamette Valley. Dry, alkaline soils east of Cascades. Acidic forest soils on coast. Generally excellent for gardening in valleys.

Oregon Climate & Growing Season

Dramatic east-west climate divide. Wet, mild winters west of Cascades. Dry, cold winters east. Year-round gardening possible in mild western valleys. Cabbage can handle frost well, which is an advantage in Oregon's climate. You can push planting dates earlier in spring and extend into fall.

Growing season length varies across Oregon: Willamette Valley (8a, 8b) has a last frost around Mar 25 - Apr 15, while Southern Oregon Coast (8b, 9a, 9b) sees frost end around Mar 5 - Mar 25. This difference matters for cabbage — but cabbage handle frost well, so the timing difference is less critical.

Growing Tips

Consistent watering prevents head splitting. Heads can handle light frost — it actually improves flavor.

Companion Planting

Plant cabbage alongside these companions for better growth:

Beets Celery Onions Dill

Keep cabbage away from:

Strawberries Tomatoes

The Bottom Line

Cabbage can be grown successfully across Oregon, but your exact planting dates depend on which region you're in. Willamette Valley gardeners should plan around a Mar 25 - Apr 15 last frost, while those in Southern Oregon Coast can typically plant earlier.
