Regular dethatching can be completed by hand or machine and is part of routine preventive maintenance for any lawn.   Essentially detaching is the removal of “thatch”, a layer of living and dead organic matter. It is mostly made up of grass stems and roots and can accumulate faster than it naturally breaks down, thus the need for lawn dethatching.


What is the difference between Power Raking and Detatching?


Both methods employ a power mower that has been fitted with knife like blades for slicing through and removing the thatch. The organic matter is then pulled to the top where is can be raked and disposed of or composted (the second option is the most environmentally friendly method.)   While the lawn will initially look a little unhealthy and unattractive the process will allow your lawn to regenerate and become better looking and healthier than ever!


Power Raking – uses the same power motor mentioned above to slice through the thatch and stolons (the horizontal connections between adjacent grass roots) thus allowing the individual roots to thrive. The result is a thicker lawn.

Dethatching – uses the same type of machine but instead of knife-like blades the dethatcher uses what are called “flail tines” which tear the stolons instead of slicing.


Why should thatch be removed?


A layer of thatch is normal within any lawn and will decay over time contributing to a healthy lawn. However, in many cases thatch will build up and accumulate over time. Grass clippings can also accumulate and contribute to the thatch. Problems associated with excessive thatch are:


  • A decrease in tolerance to heat and cold
  • A weakening of turf which contributes to weed invasion
  • More prone to insect invasion
  • Thatch is able to harbour disease causing organisms
  • Thatch makes it difficult for soil to absorb water
