About This Calendar

This calendar lays out a full year of planting actions for ZIP 04768 (Portage, ME). Each date is computed by taking the crop's documented timing — a number of weeks before or after frost — and measuring it against this location's last spring frost (May 7) and first fall frost (Oct 1). The frost dates are the median values from NOAA's 1991–2020 Climate Normals for the nearest weather station, and the hardiness zone (4a) is from the USDA 2023 Plant Hardiness Zone Map.

Dates are a planning baseline, not a guarantee — real weather varies year to year, and your own microclimate may run a week or two ahead of or behind the neighborhood. The marker beside each crop notes its frost tolerance: hardy, half-hardy, tender.

  • Hardiness zone from the USDA 2023 Plant Hardiness Zone Map.
