The Short Answer

Potatoes are best direct sown when soil temperature reaches at least 45°F. Plant 2 weeks before your average last frost date. Enter your zip code on our homepage tool for exact dates.

How to Grow Potatoes

Potatoes are the most calorie-efficient crop you can grow — more calories per square foot than any other vegetable. The 'hilling' technique (mounding soil around stems as they grow) increases yield by creating more underground stem surface for tuber formation. Green patches on potatoes contain solanine (toxic) — they're caused by light exposure, which hilling prevents. Seed potatoes from a garden center are certified disease-free; grocery store potatoes may carry diseases and are often treated with sprout inhibitors.

Direct Sowing

Potatoes can be direct sown 2 weeks before your last frost date. Plant seeds 4" deep, spaced 12" apart.

Growing Tips

Plant seed potatoes (not grocery store potatoes) 2-3 weeks before last frost. Hill soil around stems as they grow to increase yield.
