When it comes to gardening, understanding plant hardiness zones is crucial. This knowledge can be the difference between a thriving garden and a struggling one. For those living in the Peach State, Georgia, this guide will help you understand what planting hardiness zone you are in and how to make the most of it.
What is a Planting Zone?
A planting zone, also known as a hardiness zone, is a geographic area defined by climatic conditions. These zones help gardeners determine which plants are most likely to thrive in their location. The United States Department of Agriculture (USDA) has divided North America into 13 different zones, each representing a different climate.
The USDA hardiness zones are based on the average annual winter low temperature. Each zone is defined by a 10-degree Fahrenheit difference in the average low winter temperature. Zone 1 is the coldest, with temperatures below -50 degrees Fahrenheit, while Zone 13 is the warmest, with temperatures above 60 degrees Fahrenheit. Colder weather zones often bring later spring frost dates and earlier fall frost.
Georgia’s Planting Zones
Georgia, known for its diverse climate, falls into multiple USDA hardiness zones. This is due to the state’s varying geography, which includes coastal areas, mountains, and plains. As a result, the planting zones in Georgia range from zone 7a in the mountainous northern regions to zone 9a in the coastal southern regions.
The majority of Georgia falls into zones 7b to 8b. These zones experience average winter low temperatures ranging from 5 degrees to 20 degrees Fahrenheit. This means that a wide variety of plants can thrive in these conditions, making Georgia a gardener’s paradise.
As far as major cities, they are zoned as follows:
Zone 7a & Zone 7b: Dalton, Rome, Marietta, north Atlanta
Zone 8a: Columbus, Macon, south Atlanta, College Park, Augusta, Athens
Zone 8b: Albany, Valdosta, Savannah
Zone 9a: Brunswick, coastal areas

How to Use Your Planting Zone
Knowing your planting zone is only the first step. The next step is understanding how to use this information to benefit your garden. By selecting plants that are suitable for your zone, you can ensure a healthier and more productive garden.
Each plant has a range of hardiness zones where it can grow. This information is usually provided on the plant tag or in the seed catalog. For example, if a plant is labeled as “hardy to zone 8,” it means that the plant can survive winter temperatures down to 10 degrees Fahrenheit, which is the average minimum winter temperature for zone 8.
Choosing the Right Plants for Your Zone
Georgia’s diverse planting zones mean that a wide variety of plants can be grown in the state including plenty of native plants. However, it’s important to choose plants that are suitable for your specific hardiness zone.
For zones 7a and 7b, which cover north Georgia, plants such as the American Holly, Eastern Redbud, and various types of Crepe Myrtle are excellent choices. These plants are hardy and can tolerate the colder winter temperatures and earlier frost date of these zones.
In the warmer zones 8a and 8b, which cover most of central and south Georgia, gardeners can grow a wider variety of plants. These include the Southern Magnolia, Flowering Dogwood, and various types of Azaleas.
Adjusting Your Gardening Practices for Georgia’s Planting Zones
Aside from choosing the right plants, it’s also important to adjust your gardening practices based on your zone. This includes factors such as watering, fertilizing, and pruning, and understanding native plants.
In the cooler zones, such as 7a and 7b, plants may require more protection during the winter months. This could include mulching around the base of the plants to protect the roots from freezing temperatures, or using protective covers for more delicate plants.
In the warmer and sunnier zones, such as 8a and 8b, plants may require more watering during the hot summer months. Additionally, some plants may benefit from a mid-summer pruning to encourage new growth and flowering. Warm weather in spring opens the door for earlier planting in zones 8a and 8b.
For a Thriving Garden in Georgia, Know & Respect Your Zone
