Utah planting dates for potatoes
Dates for Utah vary significantly by region. Use the average frost date lookup for your specific ZIP code, then apply the standard offsets: direct sow 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 Utah's average last spring frost date of 04-25 (S) to 05-25 (N), with offsets standard across university Extension publications. For zone-specific local timing, use the frost date lookup tool with your ZIP code.
