What is a Growing Zone?

A growing zone, also known as a hardiness zone, is a geographical area that is defined by specific climatic conditions. The United States Department of Agriculture (USDA) developed a map called the USDA Plant Hardiness Zone Map, which divides the United States into different zones based on the average minimum winter temperatures.

Each zone has a 10°F temperature difference, with zone 1 being the coldest and zone 13 being the warmest. The map allows gardeners to identify the average lowest winter temperature in their area, which is crucial information for selecting plants that can survive and thrive in that climate.
