The best privacy trees for Georgia backyards are Thuja Green Giant, Nellie Stevens Holly, Cryptomeria japonica, Carolina Sapphire Cypress, Wax Myrtle, Southern Magnolia ‘Little Gem,’ and Eastern Red Cedar. Most Georgia homeowners in Zone 8a should avoid Leyland cypress due to high disease susceptibility. For fast privacy, Thuja Green Giant (3-5 ft/year) is the most widely recommended choice.
Georgia’s warm, humid climate creates specific requirements for privacy trees. Not everything that works in the Midwest or Pacific Northwest thrives here. Zone 8a means mild winters, wet springs, and hot, dry summers. This guide covers the 7 best choices for Cobb County homeowners, what to avoid, and what to check before you plant.

The 7 Trees: What to Know Before You Plant
1. Thuja Green Giant: The Top Pick for Zone 8a
Thuja Green Giant is the most widely recommended privacy tree for Georgia. It grows 3-5 feet per year in full sun, tolerates the wet-then-dry seasonal cycle well, and resists the fungal diseases that collapse Leyland cypress. Plant 6-8 feet apart for a dense screen that fills in within 3-5 years. Does not perform well in heavy shade. On a sunny fence line, it is hard to beat.
2. Nellie Stevens Holly
Slower than Thuja but remarkably disease-resistant and low-maintenance. Nellie Stevens handles partial shade better than most options on this list, which makes it a strong choice for wooded Cobb County lots. Red berries in winter are an added visual. If your site has shade or has had moisture problems where Leyland cypress failed, this is the replacement to consider.
3. Cryptomeria japonica (Japanese Cedar)
Growing 2-3 feet per year, Cryptomeria provides a fine-textured evergreen screen that handles Zone 8a well. The ‘Yoshino’ cultivar is widely available and performs reliably in Georgia’s humidity. Avoid the ‘Elegans’ cultivar, which underperforms here. Does not tolerate waterlogged soil.
4. Carolina Sapphire Cypress
An Arizona cypress cultivar that handles Georgia heat and disease pressure far better than Leyland cypress. The blue-gray foliage stands out on a fence line. Once established, it is more drought-tolerant than most other privacy options. A good choice if you want a cypress look without the Leyland cypress problems.
5. Wax Myrtle (Native)
A Georgia native adapted to the local climate from the start. Grows 2-3 feet per year and provides year-round screening, but its natural form is more shrubby and informal than the clean hedge look Thuja delivers. Better for naturalistic property-line borders than manicured suburban fence lines. Wildlife value is high.
6. Southern Magnolia ‘Little Gem’
The compact cultivar of Georgia’s signature tree tops out at 20-25 feet instead of the full-size species at 60-80 feet. Glossy evergreen leaves provide a dense, distinctive screen. The trade-off is time: plan for 5-7 years of establishment before you have full privacy. If you are not in a hurry, the result is one of the best-looking screening trees in the South.
7. Eastern Red Cedar (Juniperus virginiana)
A Georgia native with strong drought tolerance and dense evergreen foliage. Provides solid year-round screening with minimal care once established. Less uniform in shape than Thuja, so it suits naturalistic or rural-character property lines better than a formal suburban hedge line.
Why We No Longer Recommend Leyland Cypress
Leyland cypress was once the default privacy choice for Georgia subdivisions. It is not a good pick anymore.
Seiridium canker, Botryosphaeria canker, and Cercospora needle blight cause rapid and unrecoverable decline in Georgia’s climate. UGA Cooperative Extension research identifies Seiridium canker as the primary culprit for Leyland cypress decline in the state. Typical lifespan in Cobb County conditions is 10-20 years. Most Leyland cypress planted in the 1990s and 2000s are already in decline or actively failing.

HOA Considerations: Check Before You Plant
Many Smyrna, Vinings, and East Cobb HOA communities have CC&Rs governing what you can plant near property lines. Common restrictions include:
- Maximum mature height within a set distance of the property line
- Species restrictions near shared fences or common areas
- Required setback distances from structures
Planting without checking can result in required removal at your expense. Read your CC&Rs before you buy trees. Your HOA management company can pull the relevant covenant language if you are unsure.
Replacing a Bradford Pear or Dying Leyland Cypress?
Tree removal and stump grinding followed by a clean planting site means new trees go in without competing with old root systems. Removing old trees, grinding the stumps, and prepping the site for replanting is a project we handle regularly throughout Cobb County. See our guide to Bradford pear removal in Georgia if that is your current situation.
