The Importance of Aeration and Overseeding in the Fall

Perfectly striped freshly mowed garden lawnLate summer or early autumn is a great time for aeration and overseeding in East Tennessee to heal cool-season lawns that have been damaged by summer drought, diseases, lawn damaging insects or foot traffic. That’s because cool-season grasses, as their name implies, grow best when air temperatures are between 60 and 75 degrees Fahrenheit. Common cool-season grasses found in our East Tennessee area lawns include Kentucky bluegrass, perennial ryegrasses and fescues.

Aeration and its Benefits
Aeration is the process of puncturing the soil with miniature holes. This is done so the air water and other important nutrients could get to the roots easier. As a result of aeration, the roots will be stronger and your lawn more vibrant.

Benefits of aeration:

  1. It reduces soil compaction. Having hard soil is not good for your lawn. But, if you have loose soil, grass roots will be able to go deeper into the soil. This is important when they need to go deep in search of water.
  2. It reduces thatch. Thatch (that’s accumulated grass stems and roots) are an ideal environment for pests and certain diseases that can attack your lawn.
  3. It provides better seed germination. With aeration, seeds will be able to germinate more easily. The reason for this is they can hide in the aeration holes you make for them.
  4. It offers better access to the root zone. Like we said before, air, nutrients and moisture will be able to get all the way to the root zone much easier if you made some aeration holes beforehand.

Overseeding and its Benefits
Overseeding means seeding over a lawn that already has grass on it, but is performing badly.

There are two reasons for overseeding. For one, this is a good option if you have a warm-season grass which becomes brown during winter. When that starts to happen, you can simply overseed with some cool-season grass. The result will be a green lawn through the entire year.

Another reason for overseeding is if you have a thin or patchy lawn. The soil here is clearly not performing that well, so it’s time to get some seeds over it.

Benefits of overseeding:

  1. The grass will be more resistant to disease. By introducing more than one type of grass seed, there is less chance your lawn will catch a disease.
  2. It thickens the existing turf. Grass doesn’t last forever. In time, and due to heat, drought, foot traffic, pet waste, or some other factors, you will need to replace it.

In addition to these benefits, both aeration and overseeding will help reduce weeds. A dense lawn is the best defense against nutsedge (appears in thin spots), crabgrass (grows in thin areas) and broadleaf (these weeds will grow wherever there is little grass).

Finally, aeration and overseeding will help make your lawn look better. If the lawn was attacked, aeration and overseeding will see the grass germinate in 7 to 10 days.
