Benefits of Core Aeration and Over Seeding

Between the summer stresses of drought and disease, and every day activities that lead to soil compaction; your lawn may not be looking its best by time the fall rolls around. To help combat these stresses and maintain a lawn, often a core aeration is recommended for its many benefits for the lawn. For those that may not know, core aeration is the process of mechanically removing plugs of soil and depositing them on the surface.

 

Soil Compaction

Over time your lawn can become compacted with every day activities; dogs running around, children playing, parties with large groups of people on your lawn and even mowing the lawn with heavy equipment. The first benefit of core aeration is that it helps reduce soil compaction. Soil compaction is the compression of soil particles which reduces pore space. Pore space is the area between the soil particles where water, nutrients and air travel through to get to the roots. If the pore space in the soil is compacted, the nutrients, water and oxygen are not able to reach the roots.

Thatch Layer

Another benefit of core aeration is to reduce the thatch layer. Thatch, the organic layer of roots, living and dead shoots and stems that develop between the grass and the soil surface. When the thatch layer is too thick it impedes the infiltration of water, oxygen and nutrients. Also, disease and insects harbor in this area and can be detrimental to a lawn.

During a core aeration, microorganisms from down inside the soil are pulled up to the surface inside of the soil plug. These microorganisms help to breakdown that thatch layer as they look to go back to where they came from.

Strong Roots

Core aeration also helps to enhance rooting or root growth into the surrounding soil. When spaces in the soil are created by the core aeration process, the grass roots grow into the blank spots creating a stronger, fuller root system.  Also food, water and air will have easier access to the roots where they can be used.

Seeding

Over seeding after a core aeration has many benefits as well. The first benefit is that the soil is prepared to receive seed; meaning the seed will contact the loose soil, which is very important for seed germination.  The holes created by the core aeration will provide a seed bed for the grass seeds that fall into them after they are spread over the lawn.

The next benefit to over seeding is that it will help to reduce weeds and crabgrass. Weeds and crabgrass are opportunist, they will grow in any bare or thin areas that they can. By improving the turf density in these bare or thin areas with new grass, you are effectively reducing space for weeds and crabgrass to grow and take over.

By over seeding after core aeration you are incorporating newer grass varieties. Each year new grass varieties come out onto the market that are superior to the older ones. Some of the benefits to these newer grasses would be more drought, insect and disease resistant and tolerant.

Core aeration and over seeding is meant to “spruce up” your lawns appearance. This process improves the appearance of a lawn with small bare or thinned areas. This type of seeding is not recommended for lawns that have zero grass like new construction, a complete renovation from scratch, or large areas of lawn that are completely bare.

When to seed

The best time of year for seeding is early fall, specifically from the middle of August through September.  Seedings are more successful in September because crabgrass preventers that have been applied in the spring will be broken down and gone by then and crabgrass preventers and weed controls can interfere with seed germination. Also, by September any crabgrass plants that have germinated throughout the season are at the end of their life cycle and are dying off, thus creating less competition with the newly germinated grass seeds.

Another reason the fall is a great time for both core aeration and over seeding is because the environmental conditions are great. The heat of the summer has subsided, and we have cooler days and nights that helps the lawn recover from a core aeration. Soil temperatures are moderate and are conducive to seed germination and soil moisture can be maintained adequately from regular watering and rain, during this time of year.
