A healthy lawn requires adequate water, an exchange of oxygen and nutrients and a level of microbial activity in its soil. A thatch layer (an accumulation of roots, crowns, and grass clippings which creates a dense mat of vegetation at soil level) acts as an insulator, keeping soil temperatures low and helping to retain moisture. However, when thatch buildup exceeds 1/2 inch, it can prevent the exchange of water and vital nutrients fro the atmosphere to the soil, decreasing the turfs ability to thrive and fight disease and dehydration. De-thatching, also know as combing or power raking, is a process that removes unwanted thatch. It's recommended to de-thatch in early spring or late fall to allow the lawn a better chance of recovery after combing.
Thatch is a dense mat of roots, stems and grass clippings that accumulates between the soil and the growing blades of grass.
Detaching will effectively remove thatch build-up.
With thatch removed, air, water, nutrients, herbicides and pesticides can do their job. Turf becomes healthier and more resistant to insect damage and disease.
Detaching at regular intervals promotes a denser growth and ensures you\'ll have a vibrant lawn.
