Q: What is de-thatching and its purpose?

A: De-thatching is a process that removes thatch from a lawn. Thatch is a layer of dead and decaying organic matter located where the grass emerges from the ground.
If it becomes too thick, it will not break down and forms a dense layer that tends to be impermeable to water.

[singlepic id=204 w=320 h=240 float=right]A thin layer of decomposing plant material in a lawn is considered healthy as it protects the crown of the grass and helps control the temperature of the grass. This thin layer is sometimes called the “mat”.

Thatch – not to be confused with “mat” – is a dense layer of more than 1.5 cms. (1/2 inch) that prevents light, water and nutrients from reaching the grass. A thick layer of thatch also provides the perfect hiding place for insects like chinch bugs. Leaving your mulched grass clippings on the lawn will not contribute to thatch unless a severe problem already exists.
