USDA hardiness zones present

Agriculture in New Hampshire is built around small, diverse family farms rather than large-scale commodity production, with dairy, greenhouse and nursery products, and specialty crops forming the backbone. Direct-to-consumer sales through farm stands, farmers markets, and pick-your-own operations are a major part of how growers reach customers. This mix makes the state a good fit for gardeners and small producers who value locally grown food and a strong farm-to-table tradition.

Farming in New Hampshire

New Hampshire's farm economy is led by dairy, greenhouse and nursery products such as bedding plants and ornamentals, and hay grown to feed livestock. The state is well known for its maple syrup, produced from sugar maples tapped in late winter and early spring, and for apple orchards that also draw fall agritourism. Vegetable growers raise sweet corn, pumpkins, squash, and mixed produce, while livestock includes dairy and beef cattle, poultry for eggs, and sheep. Christmas trees and other forest products round out a farming character defined by small acreage, diversity, and direct marketing to local buyers.

Climate and growing conditions

New Hampshire has a humid continental climate with cold, snowy winters and warm summers, and conditions vary sharply from the milder seacoast to the cold White Mountains in the north. The frost-free growing season generally runs from about 90 days in northern and higher-elevation areas to roughly 150 days along the southern seacoast. USDA hardiness zones range from about 3b in the far north and mountains to around 6a in the warmer southeastern part of the state.
