Oregon planting dates for cucumbers
Dates for Oregon vary significantly by region. Use the average frost date lookup for your specific ZIP code, then apply the standard offsets: start cucumbers indoors 3 weeks before your last frost; transplant 2 weeks after last frost; direct sow 1 weeks after last frost.
Why these dates
Cucumbers germinate quickly in warm soil (70F+) but get destroyed by cucumber beetles - row covers until flowering are essential in much of the US.
The dates above are anchored to Oregon's average last spring frost date of 04-15 (W) to 05-25 (E), with offsets standard across university Extension publications. For zone-specific local timing, use the frost date lookup tool with your ZIP code.
