USDA Hardiness Zone Map For New Hampshire
Updated: January 6, 2023
Part of successfully growing a garden is knowing your USDA hardiness planting zone. USDA plant hardiness zones are the standard by which gardeners and growers can determine which plants are most likely to thrive at any given location. Some plants are able to survive outside of their hardiness zone, but can only survive for one growing season and are therefore considered annuals .
New Hampshire’s plant hardiness planting zones range from 3b, where winter temperatures can drop as low as -35 degrees Fahrenheit, to a much milder 6a, where winter temperatures only drop to -10 degrees Fahrenheit.
