What is lawn aeration and how does it work?
Lawn aeration is a lawn care process that involves creating small holes in the soil to improve air, water, and nutrient circulation. This process helps to loosen compacted soil, promote healthy root growth, and enhance the overall health and appearance of the lawn. Aeration can be done using various methods, including manual or machine-based techniques, such as spike aeration, core aeration, or deep drilling. The choice of method depends on the type of grass, soil condition, and the desired outcome.
The aeration process typically involves removing small plugs of soil and grass, known as cores, to create holes that allow air, water, and nutrients to penetrate deeper into the soil. This helps to reduce soil compaction, improve drainage, and increase the availability of oxygen and nutrients to the roots. As a result, the lawn becomes more resistant to disease, pests, and environmental stress, and it can recover more quickly from damage. Regular aeration can also help to maintain a healthy thatch layer, which is the layer of dead and living plant material that accumulates on the soil surface, and prevent the buildup of excess thatch, which can lead to lawn problems.
Can aerating a lawn really damage it, and if so, how?
While lawn aeration is a beneficial process, it can potentially damage the lawn if not done correctly.
