Lawn dethatching can be crucial to keeping your grass and soil healthy. Even if you are mowing and doing everything else necessary for your lawn, thatch can build up. Over watering and over fertilization can cause excess thatch. Detaching removes the thick layer of dead plant material (thatch). This allows air, water, and nutrients to reach your plants and soil again. Dethatching allows your lawn to drain better as well. A side benefit can be the partial removal of moss which gives your grass a higher chance of filling back in.
