Growing potatoes in zone 1

Plant certified seed potatoes 2–4 weeks before last frost — sprouts emerging into a late freeze regrow. Hill soil up around stems twice; tubers exposed to light turn green and bitter.

Zone 1 covers interior and Arctic Alaska — extremely short season — most crops need transplants, season extension, or a greenhouse. Zone dates are medians: frost timing varies within a zone with elevation and terrain, so treat these windows as a solid default and refine them with your own city’s dates below.

These windows use zone 1's typical frost dates (last frost ~Jun 15, first frost ~Aug 25). For windows computed from your frost dates, run the ZIP code frost lookup and open the planting calendar — it remembers your city. The seed starting scheduler turns the whole seed rack into one printable, date-sorted list.
