How to Use This Calendar

All dates are based on average last frost dates for each zone and adjusted for typical New England weather patterns. Your specific microclimate — elevation, proximity to water, urban heat — can shift dates by one to two weeks in either direction.

Always check your overnight low temperatures before transplanting warm-season crops. A single frost at 28°F will end tomatoes, peppers, and basil. The calendar is a guide. The thermometer is the rule.

Find your exact last frost date by zip code at the Old Farmer's Almanac.
