Dethatching is simply the process of removing thatch (excess grass clippings) from the underlayer of the lawn. Every time you cut your grass you will leave some clippings behind, whether you bag, mulch or just let it blow out the side. In time these clippings do break down and give important nutrients to your lawn, however if you don't cut your grass frequently or simply let the clippings blow there is a good chance that you have a large thatch buildup. A simple test for this is to take a stiff rake (such as a bow rake) and rake a spot in the lawn. If there seems to be a lot of dead grass coming out, that is a good sign it's time to get it taken care of. Thatch basically just smothers out your grass and keeps your grass from being healthy and looking full, leaving you with a thin, patchy lawn that will become full of weeds as the grass dies and is replaced. Contrary to popular belief, most types of fescue do not spread on their own (Creeping Red, Bermuda and others excluded). In this part of the country almost everyone has KY 31, Falcon or Rebel grass seed, all of which do not spread naturally. Seeds do not actually develop on grass blades until they grow above 6 inches and develop seed pods, otherwise it is simply weeds filling in.
