Oregon planting dates for carrots
Dates for Oregon vary significantly by region. Use the average frost date lookup for your specific ZIP code, then apply the standard offsets: direct sow 3 weeks before last frost.
Why these dates
Carrots are slow to germinate (14-21 days) and need loose, rock-free soil at least 8 inches deep. Avoid fresh manure - it causes forking.
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.
