Dethatching a lawn is not a necessity. But when done properly, lawn dethatching can really increase the quality and health of your lawn.

Many people have issues with their lawn, and are not even sure of what thatch is and how it affects the health of a lawn. Thatch is an organic layer of debris usually made of dead and alive plant material. This usually forms where stems meet the roots at the soil. This can build up and turn into a thatch layer. In small amounts this is good for your lawn, but when over 1 inch, it can cause major issues. It is definitely something to worry about and take care of regularly.

Lawn aeration is defined by Biggs and Straton, as a perforation of the soil with small holes to allow air, water and nutrients to penetrate the grass roots.

Aeration essentially breaks up the layers of soil, and helps the roots grow much deeper and stronger, therefore creating a lawn free of weeds and turf which is very resilient.
