This is a service that I offer in the spring. I will often cut the grass, aerate then power-rake. I do it in this order so that the plugs of soil are not left behind to leave lumps. After the power-raking AKA de-thatching, I will vacuum the grass clipping and thatch that has come to the surface. If your wanting fertilizer, I use a slow release. Most people just want a clean, green lawn. There is a per - bag fee for the Vacuuming .
