Knowing your growing zone is crucial for selecting plants that can survive Nashville’s winters and thrive in its climate.

Understanding Nashville’s Growing Zone

The USDA Plant Hardiness Zone Map divides North America into zones based on average annual minimum winter temperatures. These zones are a helpful guide, but it’s important to remember that microclimates can exist even within a small area. Factors such as elevation, proximity to bodies of water, and urban heat islands can influence local temperatures. Therefore, observe your specific location and consider any localized weather patterns that deviate from the general zone designation.
