The best time to plant cool-season grass in Tennessee is between late August and mid-October. Plant warm-season grasses between mid-May and early June.
Tennessee is in the transition zone, meaning both warm- and cool-season grasses grow here. Each has its own needs and preferences. We’ll explain what they are in this article.
Warm-season grasses: Mid-May to early June
The best time to plant warm-season grasses like Zoysiagrass, Bermudagrass, and centipedegrass is between mid-May and early June. This is the optimal time for grass growth, as the chart above shows. During this time, the daytime temperatures average around 80°F and the soil temperatures average 60 to 65°F, which are ideal conditions for warm-season grasses.
May to June is also a great time to apply a round of fertilizer, as your grass is coming out of dormancy. Read our article, When to Fertilize Your Lawn in Tennessee, to learn more.
Cool-season grasses: Late August to mid-October
As the illustration above shows, cool-season grasses grow best when planted between late August and mid-October. During this time, the soil temperatures are between 50 to 65°F, the daytime air temperature consistently reaches between 60 to 75°F, and the nighttime temperatures hover around the mid-50s, all of which are ideal growing conditions.
Spring planting
It’s possible to plant cool-season grasses in spring, but planting in fall is preferred for the following reasons:
- The soil is still warm from summer, but the air is cooler. Both encourage grass growth.
- Fall planting gives your seedlings two growing seasons before summer arrives.
- Fewer weeds.
When to overseed your Tennessee lawn
The best time to overseed your Tennessee lawn depends on your grass:
- Warm-season grass: between May and June.
- Cool-season grass: between September and mid-October.
Pro Tip: Aerate your lawn before overseeding it to expose more soil, which helps it establish and germinate. Read our article, When to Aerate Your Lawn in Tennessee, to learn more.
