BENEFITS OF AERATION AND OVERSEEDINGby Heather Wehling on 04/02/18
Every year our lawns go through quite a bit… weather, people, our 4 legged friends. It goes through a lot in the course of a year. The weather alone in Nebraska is so unpredictable (like now, um spring? Hello?!), it’s amazing it does as well as it does! So how do we make it better and more resistant to everything? Core aeration and overseeding! Let’s explore why…
Aeration is the process of removing portions of soil from the lawn using a machine similar to a lawnmower, called an aerator. Once aeration is performed, plugs of soil are pulled from the ground leaving behind about 2” to 4” deep holes. There are four benefits to aerating the soil your lawn is on: the reduction of soil compaction, reducing thatch build-up, it creates root accessibility, and encourages seed germination.
Four amazing benefits of aeration for your lawn:
- Reduction of Soil Compaction. Aeration allows for oxygen, water, microorganisms, beneficial bacteria, and nutrients to live in it. These elements make a healthy vibrant lawn pleasing to look at and play on it. If aeration isn’t performed, the soil will become hard as a rock, making it impossible for all grass to grow healthy and strong, leaving it susceptible to disease.
- Reduction of Thatch. Thatch is the build-up of grass stems and roots, which cause lawns to become ill. Aeration can reduce the amount of thatch in your grass, allowing it to live healthy, longer, and virtually disease-free.
- Root Accessibility. This is a huge benefit to all lawn owners. The reason why is because when you feed your lawn via pellets or liquid fertilizers, the exposed roots will consume that food much quicker and more efficiently than if the soil was compacted. The aeration process eliminates run-offs and it allows for lawn food to remain right where you need it most, the roots.
- Seed Germination. During the process of aeration, these 2? to 4? holes left behind become a place for the seed to fall into and the actual soil cores that get pulled out become like storehouses where grass seeds can germinate and establish root systems. You will love your lawn even more so after aeration is done.
Why overseed your lawn?
The perfect time to overseed is right after aeration. This allows grass seed to settle into the soil holes left behind by the aerator thus introducing new, healthy grass, giving the existing grass a push to be more resilient to disease, the reduction of weeds, and the enhancement of the lawn’s appearance.
Four benefits of overseeding your lawn:
- Overseeding introduces new grass growth to existing lawns; grass that can perform better in the spring or in the cold days of winter.
- New growth brings new strength to the existing turf, giving it the resistance necessary to fight diseases that can bring a beautiful lawn to an end.
- Reduction of weeds. We all recognize how important it is to stay on top of maintaining our lawns to keep weeds from propagating. In combination with aeration, overseeding is the secret weapon to minimize the amount of weeds.
- Last but not least: overseeding in conjunction with aeration will give your existing lawn a facelift. As time passes, you’ll notice your lawn looking beautiful, radiant, and inviting to spend some time on it playing, resting, or perhaps even picnicking on your days off.
