How and When to Plant Grass Seed in Georgia

Planting grass seeds in a new lawn.

Planting grass seed at the right time is the first step to achieving a beautiful lawn. The best times to plant grass seed in Georgia are summer (for warm-season grasses) and fall (for cool-season grasses).

The Peach State is home to various climates that can accommodate both warm-season and cool-season grasses, depending on where you live. We’ll go into detail about when to plant grass seeds for your preferred grass and how you can plant and maintain a lush green lawn.

Typically, the best time to plant warm-season grasses in Georgia is during summer, while the right time to plant cool-season grasses is in the fall.

  • Warm-season grasses: Late spring to early summer are the best times to plant warm-season grasses.
  • Cool-season grasses: Late summer to early fall are the best times to plant cool-season grasses. But if you miss the opportunity, spring is the second-best season to do so.

But know that each grass species has an optimum period to plant. Here are some of the best grass seeds for Georgia lawns and when to plant them if you’re establishing a new lawn:

  • Zoysiagrass: May and June are the best months to plant Zoysiagrass seeds in Georgia. April and July are also possible months.
  • Bermudagrass: To seed Bermudagrass in Georgia, May, June, and July are the best months. But it is possible to seed in April and August also.
  • Centipedegrass: The best months to plant centipedegrass in Georgia are May, June, and July. August is also possible.
  • Tall fescue: The best month to seed tall fescue in Georgia is October. Other possible months are September, November, and from February to March. 
  • Kentucky bluegrass: September and October are the best months to seed Kentucky bluegrass. It is also possible to plant in November, February, and March.

Keep in mind that the best months for overseeding or sodding each grass type are slightly different from the best months for establishing a new lawn from seed. If you want to learn more about when to overseed or sod each grass species, you can check out the UGA lawn calendars.

Pro tip: If you’re having a hard time deciding which grass is the best for your lawn, you can consult with your local county Extension office. They can advise you on the best cultivars for your home.

Now that you know the appropriate time to plant your grass seeds, let’s go through a step-by-step on how you can plant your grass seeds

  • Choose the right grass: The first step is to select the right grass seed. Georgia has distinct regions with different planting zones, which makes the state suitable for warm-season and cool-season grasses, depending on the region in which you live.

    Cool-season grasses are better suited for the northern part of the state, while warm-season grasses grow best in the central and southern portions.
  • Conduct a soil test: Before starting any preparation, conduct a soil test. A soil test can tell you important information about your soil, such as the pH, nutrient levels, salinity, and other factors. Depending on the results, you might have to use some type of soil amendment before seeding.
  • Clean the area: Remove any debris or other obstacles from the area, such as weeds, tree stumps, and rocks. If your soil is compacted, aerating your Georgia lawn might be necessary. Breaking up the soil will create space for the nutrients to reach the seeds and the root zone, allowing seed establishment.

  • Prepare the seedbed: Level the soil with a leveling tool or a rake so there are no low areas that accumulate water. Then till 2 to 4 inches of topsoil to prepare the seedbed to receive the seeds.
  • Plant the seeds: Spread the seeds with a seed spreader and overlap passes to guarantee even coverage. You can also do a bi-directional pattern, first spreading the seeds horizontally (left to right or vice-versa) and then vertically (up and down). You can use fungicide-treated seeds for extra protection against diseases.
  • Lightly rake the area: After spreading the seeds, lightly rake the area with the back of a rake to cover them evenly with soil. Be careful not to move the seeds around.
  • Apply starter fertilizer: After raking, apply a starter fertilizer to boost the growth of the grass as it grows. For the first four weeks, water daily, up to three times per day, with up to 1/4 inch of water.

How to grow grass in Georgia

After you plant your grass, knowing how to take care of it properly is the way to guarantee your lawn will be as beautiful as it is healthy. Follow these tips for a good lawn management plan:

  • Mow at the recommended height: Follow the recommended mowing height for your grass type and keep your lawn mower blades sharp. Clean cuts will prevent damage to the grass blades. Regardless of the recommended mowing height, one key lawn mowing tip is to never cut more than 1/3 of the leaf blade in one single mowing.
  • Water appropriately: Proper watering is key to ensure grass growth. One inch of water is usually enough to wet the soil 6 to 8 inches deep, which is the ideal depth. Early mornings are the best time to water the lawn, from 5 a.m. to 9 a.m.
  • Test the soil every year: Annual soil testing is a great way to assess your soil needs. That way you’ll know which amendments and fertilizer (and how much) to use to strengthen your lawn, which helps the grass resist insects and diseases and tolerate stress.

    A pro tip for warm-season grasses is to wait until soil temperatures consistently reach 65 F for the first spring nitrogen application.

Dethatch: Excessive thatch stops water, sunlight, and nutrients from properly reaching the soil. So if you have a thatch layer of 1/2 inch or more, dethatching your lawn is a must. 

  • Treat weeds, diseases, and pests: A good lawn care routine is the best way to prevent problems such as weeds, diseases, and pests. In case you see common Georgia lawn weeds, pests, or diseases appearing on your lawn, the first step is to correctly identify the problem so you can take the appropriate action. 

    Pro tip: In the case of lawn weeds, you can apply pre-emergent weed control before they germinate or a post-emergent product to control the ones that are actively growing.
  • Pay special attention to shaded areas: If your lawn has shaded areas, mow the grass higher so the leaf blades have more space to absorb light. Other tips for shaded areas are to prune the trees and shrubs to reduce the shade and hold back on the fertilizer (apply 20% to 50% less than what you would apply where the lawn gets full sun).

    Another solution is to invest in a landscape design for your Georgia home so the nearby trees and shrubs do not project shade onto your lawn. Or you can make the best out of what you already have and build a shade garden instead.
