When to aerate your lawn in Georgia depends on what type of grass you have. Homeowners with warm-season grass should aerate in the spring; those who have cool-season grass will want to aerate in the fall.

Late spring to early summer is the ideal time to aerate your warm-season grass. Warm-season grass is by far the most common grass you will find in Georgia. You always want to aerate your lawn when it’s actively growing to help relieve compaction and allow air, water, and nutrients to reach the roots. 

When preparing to aerate, mow the grass short to make it easier for the aerator to remove plugs. Do a first pass going in one direction. Then do a second pass over your lawn perpendicular to the first. Aerating in multiple directions ensures you’re getting good coverage over the entire lawn.

Warm-season grasses in Georgia

  • Bermudagrass: This highly drought-tolerant grass is a great choice for Georgians due to its tolerance of salt and heat. Bermudagrass is great for Georgia’s coastal areas.
  • Centipedegrass: A low-maintenance grass, centipedegrass is one of the best grass types for Atlanta’s Piedmont region as well as southern parts of the state.
  • St. Augustinegrass: Most recommended for residents living in the middle and lower regions of the state. It will tolerate some shade and salt, but it doesn’t like cold weather.
  • Zoysiagrass: Highly recommended for northern parts of Georgia, but this grass is one of the easiest grasses to grow anywhere in the state. Zoysiagrass is a low-maintenance turf that has cultivars that do well in cold weather despite being a warm-season grass.

When aerating cool-season grass, it’s always recommended to aerate in the late summer to early fall. Most of Georgia will not be able to grow cool-season grass very easily; however, residents in the northern regions of the state may find cool-season grasses to work best for their properties. 

Aerating in the fall will help the roots of your grass grow deep in preparation for the harsh winter season. 

Cool-season grasses in Georgia

Fine fescue: Not as easily grown in Georgia as tall fescue but can be used to overseed your lawn in the fall.

Kentucky bluegrass: This grass grows well in the mountains in north Georgia but doesn’t do as well as tall fescue. Kentucky bluegrass has a bright green color and is often blended with tall fescue grass seeds.

Perennial ryegrass: This grass is good to use as an annual and overseed into your Zoysiagrass or Bermudagrass lawn during your fall lawn care routine.

Tall fescue: This low-maintenance grass can be grown in the mountainous and Piedmont areas of the state. Tall fescue is also known to have a deeper root system and can handle drought well.

What is aeration?

The word aerate implies you are adding air to something. In this case, you are improving airflow to your dirt by puncturing and pulling out plugs of soil. This allows air as well as water and nutrients to have a clear path to penetrate the soil, allowing for better access to the grass roots.

Types of aerators:

  • Solid tine aerator: This punctures a hole in the dirt without removing any soil.
  • Hollow tine aerator: Using this tool creates holes by using hollow tubes to pull out plugs of soil. These machines can be gas-powered or manual.

  • Lessens compaction
  • Promotes healthy grass growth
  • Reduces thatch buildup
  • Will cut down water runoff

  • Bare patches
  • Water is not absorbing
  • Soil compaction
  • Thatch is more than 1 inch

Additional Georgia resources

It’s easy to assume all plants that grow well in warm climates will grow well in Georgia. While there may be some truth to that, it’s also not completely accurate. 

Some plants do well in extremely hot, dry climates, but let’s face the facts: Georgia is not known for its dry heat. Humidity is a fact of life for the majority of the state.

FAQ about aerating your lawn in Georgia

How deep should you aerate your lawn?

It’s recommended to aerate your lawn 2-3 inches deep. Holes should be spaced 3 inches apart. This will encourage healthy roots and help with compaction.

What should you do after aeration?

After aeration, be sure your lawn gets the proper amount of water to aid in its recovery. An established lawn needs approximately 1 inch of water per week. 

It’s always best to water in the morning, or if you can’t water in the morning, the next best time to water your lawn is in the early evening (to minimize evaporation). But watering in the evening is not recommended on a regular basis due to the risk of fungal disease.

How often should I aerate my lawn?

The frequency of aeration will depend on the type of soil on your property. Lawns that have a heavy clay presence often need to be aerated once a year to help alleviate the compaction. If your lawn has sandy soil or doesn’t compact as easily, then once every three years is typically acceptable.
