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. These zones help gardeners and horticulturists determine which plants are most likely to thrive in a particular area.
Understanding the USDA Plant Hardiness Zone Map
The USDA Plant Hardiness Zone Map is divided into thirteen zones, ranging from zone 1 (coldest) to zone 13 (hottest). 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.
