Louisiana planting dates for potatoes
| Phase | Date in Louisiana | Notes |
|---|---|---|
| Direct sow outside | March 1 | 2 weeks before last frost |
Why these dates
Potatoes are cool-season but frost-sensitive. Plant seed potatoes 2-3 weeks before last frost when soil reaches 45-50F at 4 inches deep.
The dates above are anchored to Louisiana'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.
