1b Planting calendar for zone 1b

A year-round growing season

Zone 1b (average annual extreme -55°F to -50°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.
