De-thatching your lawn is a vital part of having a successful, green, weed-free lawn. De-thatching is the mechanical removal of the layer of dead turfgrass tissue know as "thatch." This thatch is really bad for your lawn, as it keeps water and nutrients from seeping down to the grass roots. Preventing thatch buildup is not nearly as big a part of lawn care as is mowing, but you should not overlook its importance to the long-term health of your grass. We use a machine has vertical blades that slice into thatch and lift it to the lawn surface. After this process is complete, there will usually be a very large quantity of dead grass that comes to the surface that we will then clean up and haul away.
