Arizona planting dates for cucumbers
| Phase | Date in Arizona | Notes |

| Start seeds indoors | February 22 | 3 weeks before last frost |
| Transplant outdoors | March 29 | 2 weeks after last frost |
| Direct sow outside | March 22 | 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 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.
