What Growing Zone Is Kentucky?
Kentucky, known as the Bluegrass State, is located in the southeastern region of the United States. With its diverse climate and fertile soil, it offers great potential for gardening and agriculture. To determine the best plants for your garden, it is essential to understand the growing zone of your area. The growing zone of Kentucky varies across the state, ranging from zone 6b to zone 7a. Let’s explore what this means for gardeners in Kentucky and answer some frequently asked questions about growing zones.
Understanding Growing Zones:
Growing zones, also known as hardiness zones, categorize regions based on their average minimum winter temperature. The United States Department of Agriculture (USDA) developed the USDA Plant Hardiness Zone Map, which divides the country into 13 zones. Each zone represents a 10-degree Fahrenheit difference in average minimum temperatures. This information helps gardeners choose plants that are most likely to thrive in their specific climate conditions.
Kentucky’s Growing Zones:
Kentucky is split into two main growing zones: zone 6b and zone 7a. Zone 6b covers the northern half of the state, while zone 7a encompasses the southern half. The dividing line approximately runs through the middle of the state, from west to east.
Zone 6b: This zone experiences an average minimum winter temperature of -5 to 0 degrees Fahrenheit (-20.6 to -17.8 degrees Celsius). Some cities falling in this zone include Louisville, Lexington, and Frankfort. Gardeners in this zone need to select plants that can tolerate colder temperatures and shorter growing seasons.
Zone 7a: This zone has a slightly milder climate with average minimum winter temperatures ranging from 0 to 5 degrees Fahrenheit (-17.8 to -15 degrees Celsius). Cities like Bowling Green, Paducah, and Owensboro fall into this zone. Gardeners in zone 7a enjoy a longer growing season compared to zone 6b, allowing for a wider range of plants to thrive.
