Importance of Lawn Detacher

Dethatching is important to your lawn because it removes unwanted material close to the soil surface which otherwise reduces your lawn’s turf potential. A good Dethatcher or Power Lawn Rake cleans the debris to allow room for the grass to grow and thrive.
Thatch is basically a layer of lawn debris, grass clippings, and other materials.
For a lawn to remain healthy, the thatch should generally be at least the height of the pinky finger.
With the assistance of bacteria, the thatch slowly breaks down which ensures that the height is consistent and offers a number of protection to the lawn like preventing the burning of grass roots and helping the lawn in retaining water.

How to Use Lawn Detacher

On the other hand, the thatch becomes thick quickly if the lawn is unhealthy. The lawn might be over fertilized, or this may be due to the compaction of the soil which makes it hard for bacteria to reach the surface to break down the thatch. One of the quickest ways of helping out a lawn, which is unhealthy and struggling, is by pocking deep holes into the soil in order to aerate it. This draws up the bacteria so that they can start doing their work on the thatch. However, sometimes this does not work, and you will need a lawn dethatcher to dethatching.

Lawn dethatcher is just like a huge mechanical rake. You have to run the lawn dethatcher across the lawn steadily and letting the rotating blades to penetrate into the grass for pulling up the thatch. The height of the blade can be adjusted which allows for the lawn dethatcher to penetrate as much and as little as you want. You can also change the blade spacing according to your lawn’s needs. A rake is one of the alternatives to a lawn dethatcher however it can be pretty time consuming and also very stressful while not always doing the same level of job as is done by a lawn dethatcher.

Conclusion

Lawn dethatching is done best when it is winter times since this ensures that the grass shoots do not get damaged while dethatching. It is also important that you leave some of the thatch as removing all of it will hold back the recovery process of the lawn back to its normal health. Once you have removed the thatch through the use of a lawn dethatcher, you will have to rake it away. At first, the lawn will look pretty awful and not the best you have seen, however, you will have to give the lawn some time to recover after it comes back to its health. Water and fertilizers would aid this process.
