Your garden’s success is dependent upon your understanding of your gardening zone.

The 2012 map is replaced by the 2023 plant hardiness map, which is derived from weather information that has been accumulated over the course of thirty years. A warming winter temperature trend resulted in a zone shift in certain regions of the country.

In certain regions of the country, this trend toward increased temperatures presents novel opportunities for cultivators. Locate your zone by selecting the Tennessee planting zones map located above.

The state is divided into five zones: 6a, 6b, 7a, 7b, and 8a. It can be helpful to be aware of your zone information when purchasing plants. The USDA plant hardiness zone map defines the winter extreme temperatures that plants that are appropriate for your zone can withstand.

The survival of specific plants in a given region is contingent upon the availability of this low temperature data. A plant should not be planted in an area if it is unable to survive the average extreme low temperature.

Although the majority of local nurseries will only provide plants that are suitable for the Tennessee growing zones, it is always recommended to verify this information prior to making a purchase.

Certain plants that are not suitable for your winter temperatures can be treated as annuals or taken indoors during the winter.
