USDA<\/a><\/figcaption><\/figure> Note:<\/strong> Defining \u201ccentral New Hampshire\u201d can be challenging, as opinions on the exact boundaries often vary. For the sake of this guide, we’re considering the region that stretches from Littleton to Concord as central New Hampshire.<\/p>
Most of central New Hampshire falls within zone 5a<\/strong>, which experiences average minimum temperatures of -20 to -15 F<\/strong>. However, there is a significant region near southern New Hampshire that is in zone 5b<\/strong>, where temperatures range from -15 to -10 F<\/strong>. Additionally, there are some small exceptions throughout the region that fall into zones 4a, 4b, and 6a<\/strong>.<\/p>
In this guide, we\u2019ll analyze each central New Hampshire county, so we can take a more detailed look into each planting zone:<\/p>
Grafton<\/h3>
Grafton County is primarily situated within zone 5a, but there are some exceptions. Here\u2019s what you need to know:<\/p>
- Zone 5b:<\/strong> The south and southeastern parts of the county fall into this zone, including towns near Interstate 93, such as Thornton and Plymouth<\/strong>. <\/li> <\/ul>
- Zone 5a: <\/strong>Most of the county is in this planting zone, including towns like Hanover and Lebanon<\/strong>.<\/li> <\/ul>
- Zone 4b:<\/strong> Some small areas in the county\u2019s northernmost region, such as Littleton<\/strong>, and areas near the White Mountains, including Mount Moosilauke, Cannon Mountain, and Mount Lafayette, fall into this zone. It experiences average minimum temperatures ranging from -25 to -20 F<\/strong>. <\/li> <\/ul>
- Zone 4a: <\/strong>The peaks of some of the White Mountains are in this planting zone, where average minimum temperatures range between -30 and -25 F<\/strong>. Only dwarf vegetation grows here due to the harsh conditions.<\/li> <\/ul>
Tip:<\/strong> North Haverhill has areas in zone 4b, near Clark Brook, and other areas that are in zone 5a. If you’re not sure which zone you’re in, type your ZIP code in the USDA plant hardiness zone map<\/a>.<\/p>
Carroll<\/h3>
Carroll County is primarily located in zone 5a<\/strong>, which includes towns like Conway<\/strong> and Ossipee<\/strong>. The only exceptions are:<\/p>

- A small region near Intervale<\/strong> and North Conway<\/strong> that is also in zone 5b<\/strong>.<\/li> <\/ul>
