Thatch is an accumulation of living and dead plant material such as roots, stems, and rhizomes that build up between the green matter and the soil surface. Excessive thatch (over ½ inch thick) needs to be controlled because it creates a favorable environment for pests and disease, and an unfavorable growing environment for grass roots, leaving your lawn very susceptible to permanent damage. At Turf Techs, we believe in managing thatch through good cultural practices such as annual core aeration, and sensible fertilizing.
If your lawn has excessive thatch that needs to be removed we use an all natural biological liquid dethatcher as an alternative to physically removing it. Liquid dethatch treatments contain naturally occurring microbes that feast on dead plant tissue which help break down the unwanted thatch into organic matter.
