I looked at a job today where a potential client asked about her backyard. We walked back and she showed me her neighbors yard. They had some of the woods thinned out trees no bigger than 4 inch caliper and had grass planted. Im pretty confident about the job but i figure I could thin out some tree to let some light in, remove the stumps and other junk. Once its all cleaned out to prevent new unwanted growth is there anything i can do to prevent that, or should i throw down a layer of topsoil, fertilizer and seed it, any suggestions?
