Dethatching, Thatch Removal & Power Raking in Evansville
The layer of grass ( some dead, some not) and leaves and other debris that lies above the surface of the soil but mostly below the planted grass is called thatch. A certain amount of thatch is natural and even healthy for a lawn ( it slows water loss and thatch that breaks down provides nutrients for the lawn). Too much can cause problems. If the thatch layer gets too thick (3/4 of an inch or so) it can block nutrients, oxygen and fertilizer from getting to the roots of the grass. It can hold moisture against the blades of living grass & make it more prone to disease. Lawns with excessive thatch tend to grow shallower root systems, making it harder for grass to grow in the heat of summer. Dethatching is using a bladed machine to pull the dead grass up to the surface. The debris is then raked or bagged and disposed of. Thatch removal can be done any time during the growing season. but it is better to avoid doing in the extreme hot parts of summer when the grass is already stressed.
