Arizona planting dates for carrots
| Phase | Date in Arizona | Notes |
|---|---|---|
| Direct sow outside | February 22 | 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 Arizona's average last spring frost date of 03-15, with offsets standard across university Extension publications. For zone-specific local timing, use the frost date lookup tool with your ZIP code.
