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.
Thatch may be torn out with a dethatcher or vertical mower, but this practice is very destructive to the lawn. Most of your lawns roots are in the thatch instead of soil so living plants are removed easily. This leaves your lawn thin, weak and susceptible to weed and crabgrass invasion.
At Limited Edition, 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.
