Zone 2a & 2b Planting Calendar

Every listed crop, timed for zone 2b. Zones 2a and 2b share the same average frost dates in our data, so this calendar covers both. Not sure this is your zone? Change it using the zone picker at the top of the page.

This zone has a single frost date, and the windows below are based on it. That date is a long-term average, not a forecast: it shifts from year to year, and a microclimate within your zone (a valley, a coastline, an urban heat island) can run meaningfully earlier or later than the regional average. Use these windows as a starting point and watch your local forecast as the date approaches.

I = start indoors · S = direct sow / transplant outside · T = transplant (buy as a start). Click any column heading to sort.
