Lawn Core Aeration

Lawn aeration is an important process that keeps your yard healthy and free from thatch. Thatch is a mixture of decomposing grass, roots and debris that builds up between the soil and the grass. Although a small amount of thatch is healthy for your yard, a large amount can damage grass and lead to weeds, pests and diseases. Lawn aeration works by removing small samples of soil and grass from measured increments throughout a yard. This allows the soil to breath and reduces excess buildup of materials. Lawn aeration is oftentimes overlooked as a critical lawn maintenance service. However, in order to keep your lawn healthy and your grass green and manicured, it’s important to aerate your lawn. In order for lawns to maintain optimal health, yards should be aerated twice a year.  

Lawn aeration is an important part of holistic lawn care. Your lawn has many enemies, like weeds, harmful insects and disease. Many times these enemies find a safe haven in the portion of a lawn called thatch. Thatch is the layer of decomposing grass, stems, roots and debris between the soil and the grass you see above it. Some amount of thatch is healthy, but when thatch becomes overgrown, you start to see the symptoms of these unwanted lawn enemies. 

Although grass is durable, it doesn’t come without its challenges. The soil can become dry and deprived of nutrients, thatch can build up and damage or destroy grass, and your lawn can stop soaking up water efficiently. Excess run-off leaves you paying a higher water bill. All yards need lawn maintenance. Aeration provides the soil, grass, and root system with much needed care. Over time, grass and roots become compacted. Core aeration works by removing small pieces of grass, soil and roots at measured increments around your yard. Lawn core aeration is an important treatment for thatch accumulation and promotes overall lawn health by giving roots and soil access to air, water and fertilization.

Grass-eating insects, such as bill bugs, grubs and sod web worms, can kill patches of grass, leaving barren areas. These harmful insects find safe, protected surroundings in overgrown thatch.

Lawn diseases, such as snow mold, brown patch, necrotic ring spot and red thread, also kill grass and attack grass plants, causing a thinning turf cover. You’ll trace these nuisances back to thatch which has grown too thick.

So how does thatch become overgrown in a lawn? Ironically, thatch results from strong, thriving lawns. Healthy lawns develop a strong web of roots and lateral shoot growth that creates an intertwined layer, or in other words, thatch. 

Thatch has some benefits, but the problems created by excessive thatch outweigh the benefits. 

Lawn core aeration is the best way to reduce a thatch problem by removing plugs of soil, roots, shoots and grass plants. The core is then deposited on to the surface of the lawn and leaves a hole for air, water, and fertilizer - and if needed, allows seeds to find a home to germinate.

How Core Aeration Benefits Your Lawn

So, how do you maintain thatch at levels that support healthy grass? The best way to manage lawn thatch and prevent unruly over growth is with lawn aeration, specifically core aeration administered by Senske lawn care specialists.

Core aeration is a process that creates space in between the roots of grass for water, air and fertilizer to be absorbed by the soil. The soil underneath of a yard will become compacted over time because of grassroots. In order to alleviate compaction, small pieces of lawn are removed. This process is strategic and involves an expensive piece of machinery, called a lawn aerator.​


Lawn core aeration extracts a core of grass, thatch and soil, slightly larger than an apple core. These cores are removed on a grid every few inches by a special machine.The cores are deposited on top of your lawn to allow the soil and nutrients to wash out of them. The hole left behind allows water, air and fertilizer to move into the root, thatch and soil area to support healthy lawn growth. And, if you over seed your lawn, it creates a great home for that seed to germinate. This is a much different operation and much better for your lawn than classic dethatching.

Every lawn should be aerated at least once a year. If your thatch problem is severe, you’ll want to have lawn core aeration performed several times a year, twice at a minimum. Lawn aeration can be done any time of the year as long as the lawn isn’t soggy.
