What is Thatch?

Thatch is an accumulation of organic matter. Grass clippings, roots and other debris make up this layer between the native soil and the blades of grass. Thatch buildup is commonly found in lawns where grass has grown tall and lawns that have never been aerated.

What are the benefits of Dethatching?

Increased Nutrients

Thatching increases the amount of water and nutrients available for your lawn to consume. As thatch accumulates, it prevents water, nutrients, sunlight and air from reaching the roots of the grass. When this occurs, the grass is suffocated and starved, promoting an unhealthy and unsightly lawn. While a thin layer of thatch is beneficial to your lawn, protecting it from extreme weather and traffic, an excessive layer is damaging.

Increased Aeration

Thatching provides ample aeration for the desired grass and its underlying soil. Thatching’s removal of the excessive layer of decomposing material increases air circulation, promoting healthy cell growth, improving irrigation drainage, and allowing water, nutrients and air to pass directly to the root system. Aeration reduces the potential for soil compaction and helps to control thatch development.

Reduced Infestations

Insects and other pests tend to thrive in thatch areas. Removing the thatched areas disturbs the homes of these pests, forcing them out of the lawn. The process will greatly reduce, if not eliminate, infestations.

Reduced Disease

Thatching reduces the potential of grass diseases, such as leaf spot, summer patch and dollar spot. These fungal diseases overwinter in poorly aerated lawns and spread during the summer’s growing season. The potential for these diseases is high in lawns that have large areas of thatched grass.
