What are Garden Zones?
Garden zones are a classification system that categorizes the climate of an area. This helps gardeners determine which plants will thrive in their location based on temperature ranges and frost dates. The United States Department of Agriculture (USDA) created the system, which divides North America into 13 zones. Each zone is identified by a number and is defined by the average minimum temperature during winter.
What are the Garden Zones in North Carolina?
North Carolina is divided into three garden zones, which are 6b, 7a, and 7b. Zone 6b is the coldest, with an average annual minimum temperature of -5 to 0 degrees Fahrenheit. Zone 7a is slightly warmer, with an average annual minimum temperature of 0 to 5 degrees Fahrenheit. Zone 7b is the warmest garden zone in North Carolina, with an average annual minimum temperature of 5 to 10 degrees Fahrenheit.
How do Garden Zones Affect Gardening in North Carolina?
Knowing your garden zone is crucial when planning a garden in North Carolina. Since each zone has a different temperature range, gardeners can choose plants that are best adapted to their particular climate. For example, if you live in zone 6b, you should choose plants that can withstand colder temperatures and frost. In contrast, if you live in zone 7b, you can grow plants that require warmer temperatures without worrying about frost damage.
Which Plants are Suitable for Each Garden Zone?
In North Carolina, some plants are suitable for all three garden zones, while others are only suitable for one or two zones. Here are some examples of plants that can grow well in each zone:
- Zone 6b: Sweet Potatoes, Mustard Greens, Cabbage, and Broccoli
