If you are planning to grow vegetables, fruits, or flowers in New Hampshire, one of the things you need to know is the planting zone. The planting zone is a geographical area with similar climatic conditions that determine what plants can grow in the area. In this article, we will take a closer look at what planting zone is NH, and what plants are suitable for this zone.
What is a Planting Zone?
The United States Department of Agriculture (USDA) developed a system to classify planting zones based on the average minimum winter temperature. This system is called the Plant Hardiness Zone Map. The map divides the United States into 13 zones, each with a range of winter temperatures. The lower the zone number, the colder the minimum temperature in the area.
