2a Planting calendar for zone 2a

USDA hardiness zone 2a: average annual extreme minimum -50°F to -45°F. 27 US ZIP codes fall in this zone.

A year-round growing season

Zone 2a (average annual extreme -50°F to -45°F) rarely sees a true freeze, so spring/fall frost anchoring doesn't apply. Planting here follows heat, not frost — plant cool-season crops in fall through winter, warm-season crops in spring. Detailed month calendars for no-freeze zones ship in the next update; meanwhile see the month pages.
