I laid sod 2 years ago and put wood mulch down for the flower beds and all landscaped areas. I did not put down a border, I left it natural which I have been using a flat shovel to keep the border edged and looking good. Only thing is I have to do this a few times a year and I'm looking for an alternative way to keep this border looking good. I have about 400 ft. of boarder and was thinking of using a gas stick edger but I am not sure if this will work. Any ideas? Stihl makes a nice gas powered stick edger but would this work?
