Dethatching is a valuable service for encouraging a healthy lawn. Thatch is the matted layer of dead and decaying grass, stems, and roots. Grass clippings which are 80% water and decompose quickly, do not contribute to thatch. Light thatch is beneficial for lawns, it provides shade for roots and retains moisture. Larger quantities of thatch however need to be removed before problems occur.

Too much thatch calls for dethatching

If thatch is one half inch or greater, it interferes with  nutritional needs of  grass. If  thatch layer is too thick this will keep water and nutrients from reaching roots. If this occurs the grass will take on a yellow appearance. This change of color is due to lack of elements such as nitrogen and iron. Not only is this damaging to a lawn, but unhealthy grass encourages weed growth.

Excess of thatch also prevents new grass seeds from reaching the soil to germinate. These signs are all indicative of excess thatch and this calls for dethatching.

Dethatching for removal of excess

Though labor intensive, small lawns can be dethatched by rigorous hand raking. Larger lawns require power rakes or dethatchers. The process has to be properly timed to avoid damaging new grass plants. 207 Lawn Care is professionally equipped to handle dethatching of any size lawn. Our equipment is professional commercial grade and it is efficient.


One way to prevent thatch buildup is to aerate. This process removes small plugs of turf from the soil. We at 207 Lawn Care believe it’s good practice to do both. This process would provide optimum lawn and landscape care. This allows the proper nutrients, water and seeds to reach the soil. Being proactive in maintaining a lawn and landscape pays dividends in the long run. For areas with thin grass, dethatching and aeration are instrumental in lawn building.

General Observations 

Thatch is a natural result of lawn care, it is a normal element. It may go largely unnoticed until it creates a problem through excess buildup. If your lawn turns yellow or looks unhealthy, it may need to be dethatched.
