I have an upcoming job where the residence is in a development of townhomes. Everyone has Bermuda grass and its maintained by crew supplied by the management company. I am installing flower beds for my customer in her backyard. The yard has a pretty wrought iron fence and my beds are on all 3 sides. I need help with how to best remove the Bermuda grass in the spring- glyphosate or sod cutter? My biggest worry is how to do this without killing off the neighboring yards grass. Can you help me with this concern? Also how do I keep the neighbors grass from coming back in? Thanks!
