Plant Hardiness Zones in New Hampshire

Areas in New Hampshire Where Plants Are Most Likely to Thrive

Not all plants thrive under the same temperature and climate conditions. Therefore, it is important to know your state’s climate zone so you know what plants you can successfully grow there. Most gardeners use the USDA Hardiness Zone Map to determine what plants thrive in a specific location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones. Below is the growing zone for New Hampshire. New Hampshire is known for its humid continental climate. New Hampshire summers are warm and humid while winters are cold and snowy. The time in which you should plant your seeds or transplant them outside depends on what planting zone in New Hampshire you live in. We recommend growing corn, squash, pumpkins, gourds, and sunflowers here.
