De-Thatching


De-thatching is a process perhaps best described as a mechanical raking of the lawn; its primary purpose is to remove thatch from the lawn although it has associated benefits as well. The machine used has a series of sharp tungsten blades that rotate at high speed and cut into the turf in a vertical manor. The depth can be adjusted to remove as much or as little as required. This machine and process should not be confused with the typical tool available on the domestic market, which is more of a rake.


Why does my lawn need de-thatching?

A lawn that has developed a large amount of thatch or moss needs to be treated to remove as much of this material as possible, allowing the grass space to grow. This process should be carried out at a time when the grass is growing actively to allow it to recover from this rigorous process, usually autumn through to spring time. It is advisable; although not essential to carry out before a fertilizer treatment as this will greatly speed the rate of recovery from the process. This process is commonly used in conjunction with over-seeding.

All lawns are different in their characteristics and it is therefore very difficult to predict how often to De-thatch a lawn. There are a number of factors that will affect the frequency required. If a lawn contains large amounts of thatch  it may need a number of treatments to reduce the level to be manageable. Different grass types tend to produce more thatch than others along with mowing height and frequency and therefore need servicing more frequently. As a general rule We advise that a lawn should be de-thatched between every 1 and 2 years but for specific advice please discuss with your lawn manager who will be able to look at your individual circumstances.


It is a common misconception that a lawn can be de-thatched for less than $100 if done properly.  In most cases depending on thatch level, you should expect the company to be at your home for up to 3 hours for a lot  size up to 5000 square feet.  It is also a good idea over-seed and fertilize directly after this procedure.
