Growing radishes in zone 2
The fastest vegetable in the garden — and the most often ruined by crowding, so thin early. Sow small amounts weekly; in summer heat they bolt and turn pithy, so pause until fall.
Zone 2 covers central Alaska (Fairbanks area), highest Rockies — short but intense season with very long summer days — fast, hardy crops shine. 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 2's typical frost dates (last frost ~May 30, first frost ~Sep 8). 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.
