Regional guide
Oregon Four-Region Vegetable Garden
A guide for Oregon gardeners who need different planting windows for the coast, western valleys, high elevations, and Columbia/Snake valleys.
Climate signals
- Oregon State separates planting dates into Coast, Western valleys, high-elevation/mountain/plateau areas, and Columbia/Snake valleys.
- High-elevation and plateau gardens often lag warmer valley windows.
- Row covers can protect cucurbits early, but covers need to come off during bloom for bee pollination.
Planning notes
- Use the OSU regional table before choosing a statewide planting date.
- Match cool-season brassicas, beets, and greens to the local spring and fall window.
- Treat melons, squash, cucumbers, tomatoes, and beans as region-sensitive warm-season crops.
