Why Thin Lawns Need Aeration and Overseeding

 
At some point in time, many homeowners are going to experience thinning or dead grass on their property. Whether you are a first-time home buyer inheriting a poorly maintained lawn or a long-time owner, who has let yard maintenance fall by the wayside, there is a solution. One of the most beneficial ways to revive and rejuvenate your lawn is through aeration and overseeding .  

The process of aeration allows water, air, nutrients, and fertilizers to flow throughout the turf’s root system, leading to the development of dense new growth. At the same time, overseeding promotes new growth intermingled with preexisting grass.

What is Aeration and Overseeding?

Aeration

Simply put, aeration is the process of introducing air into a material. In terms of lawn aeration, it is the process of introducing pockets of air onto the surface of your lawn, using a machine called a core aerator.

This machine digs up 1-2 inch cores of soil, called plugs. Each plug consists of dirt and thatch, or the spongy and often impenetrable layer of decaying organic matter and materials found between the grass and dirt. Then, the thatch plugs are left on the surface of the lawn to be broken down by microbes, adding nutrients to the yard.

Overseeding

Once the surface of the lawn is adequately aerated, the next step is overseeding. Overseeding is just as it sounds: the process of laying seed over preexisting grass. This process is hugely beneficial in lawns that have been damaged by pests or disease, discoloration, sparseness, and other issues that can cause thinning.

By laying down newer, more resilient turfgrass species interspersed with the grass that is already there, your lawn can grow healthier and more robust. Aeration and overseeding work hand in hand to facilitate new grass growth by providing access to necessary nutrients. 

Why Do It?

Things to Remember

Before you begin the processes of aeration and seeding on your lawn, remember these few helpful tips so no damage is inflicted upon your yard:

Time to Grow

 
Annual aerating and overseeding can be extremely beneficial to the health and beauty of your lawn.  Both processes help cultivate new, healthy growth by making necessary nutrients easily accessible to the newly applied grass seed and existing lawn.  These processes can also significantly and bare spots, so your yard remains looking luscious and inviting all season long.  Another great way to improve and maintain your lawn is with our lawn fertilization and weed control service packages .  

As a homeowner, it can be challenging to complete these processes alone.  They require specific machinery and conditions to be successful.  To ensure that these vital lawncare processes get completed correctly, contact a knowledgeable and reliable lawn care specialist for assistance before embarking on these procedures.

Some people like to use the phrase "nature is healing." However, in some cases, nature can't heal itself alone. That's where we come in. Recently, a homeowner in Maple Grove, Minnesota reached out to KG Landscape after struggling to revitalize a back yard that was simply failing to thrive. Despite what seemed like ample sunlight and water, the turf suffered from numerous thin and bare patches that refused to improve. To determine exactly why they couldn't get this yard to flourish on its own, our client asked us to assess the yard and determine a plan that could reinstate the lush green lawn they expected for their Maple Grove home.

Seldom will you find a piece of landscaping less desirable than the unintentional water feature. That's why a recent client in St. Paul, Minnesota's Macalester-Groveland neighborhood reached out to KG Landscape. Poor drainage in their yard had begun to allow standing water to accumulate, which not only damaged the lawn but was also beginning to make its way into the home's foundation. Our assignment was to determine why this water was pooling where it was, then find a way to divert it to a safer outlet. In order to do so and to improve the health of this St. Paul lawn, our team developed a system of catch basins and underground drain pipes to capture and redirect rainwater. Additionally, we restored the damage standing water had done to the lawn with a full topdressing treatment combined with seed blankets in the most critical areas of the lawn. Upon completing the project, we successfully resolved the yard's drainage issues while also bolstering the health of the lawn.
