What is Thatch and Dethatching?

In order to understand the process of dethatching, it is important to first know what thatch is. Thatch is a layer of dead grass, leaves, and organic debris that accumulates on the surface of a lawn over time. This layer can vary in thickness, ranging from a few millimeters to several centimeters. While a thin layer of thatch can be beneficial for the lawn, providing insulation and protection, excessive thatch can hinder the healthy growth of grass and promote the growth of weeds.

Dethatching, as the name suggests, is the process of removing this excess layer of thatch from the lawn. It is an important step in maintaining a healthy and vibrant lawn. Dethatching can be done manually using a thatch rake or by using power tools or equipment specifically designed for this purpose. These tools typically use spinning blades or tines to lift and remove the thatch from the surface of the lawn.
