Dethatching
Lawn dethatching, also known as power raking, is a process that involves removing the layer of dead grass and other organic material that accumulates on top of the lawn over time. This layer, known as thatch, can have a number of negative effects on the health and appearance of the lawn if it is not removed regularly. Thatch is a natural byproduct of grass growth, as the grass blades, roots and other organic material that make up a lawn will die and decompose over time. However, if the thatch layer becomes too thick, it can cause several problems for the lawn. Some of these problems include:
Poor water penetration and retention in the soil
Poor air circulation and oxygenation of the soil
Impeded root growth and development
Reduced grass growth leading to a less lush lawn
Reduced effectiveness of fertilizer and other soil treatments
Reduced effectiveness of grass seed application
Increased risk of lawn pests and diseases
To combat these problems, lawn dethatching is often recommended. This process involves removing the thatch layer using specialized equipment, such as a dethatching rake or a power dethatcher (power rake). For the best results, we always recommend using a power rake, as it is much more effective at removing thatch. The machine that is used utilizes a row of sharpened pieces of sheet metal, spinning vertically. These are able to bypass the standing grass blades of the lawn to dig up and rake out all the thatch and organic matter sitting on the surface of the soil. Once this is done, we then use large fan rakes to rake up all the lifted thatch and debris, remove it from the lawn, and bag it in enviro-bags. The benefits of lawn dethatching are many, and can have a significant impact on the overall health and appearance of the lawn. Some of the most notable benefits include:
Improves water penetration and retention in the soil: By removing the thatch layer, water is able to penetrate the soil more easily, which helps keep the roots of the grass hydrated and healthy.
Enhances root growth and development: Removing the thatch layer allows for better air and nutrient circulation and penetration, which promotes healthy root growth and development. This leads to a stronger, more resilient lawn that is better able to withstand stress and damage.
Reduce the risk of lawn pests and diseases: The thick layer of organic material that makes up the thatch layer can provide a perfect breeding ground for ground pests and diseases. By removing this layer, the risk of pests and diseases is significantly reduced, which helps keep the lawn healthy and beautiful.
Improves air circulation and oxygenation of soil: The thatch layer can make it quite difficult for air to circulate through the soil, which leads to poor oxygenation and poor growth of the grass. Thatch removal will help improve this circulation, which will lead to healthier roots and therefore a thicker, fuller lawn.
Increases the effectiveness of fertilizer and soil treatments: Once the thatch layer is removed, the soil is able to absorb nutrients and other treatments more effectively. This can help to ensure that the lawn is getting the most benefit from any treatment applied to the lawn.
Greatly increases germination of new grass seed: The thatch layer can act as a barrier preventing new seed from germinating and rooting into the soil. Additionally, if the grass seed is sitting on top of the thatch, it can dry up completely after being watered, preventing it from ever growing. Once the thatch layer is removed, the grass seed is able to sit directly in the soil. This direct seed-to-soil contact dramatically improves germination of new seed, as it makes it much easier to keep the seed damp, preventing it from drying up in the sun.
Promotes healthy grass growth and a lush lawn: All in all, removing the thatch layer is one of the best things you can do to promote healthy growth of your lawn. Dethatching can help achieve a lush, thick lawn that is better able to withstand pests, diseases, drought, and other problems.
