What do u guys think about "Edgers". I've always turned my trimmer upside down and with a steady hand made the grass look like it's been edged pretty nice and have got lots of compliments about how I do it. One customer who has nice grass that grows up well on the edges that I do normally with my trimmer. His is one of my best examples. THen I come by today and I think some "other" lawn guy must have been there as both my customer and his neighbor obviously got new mulch installed ( which of course I do also but they probably have been using this guy for things like that for years and u know how it goes, it's cool) BUT someone ( probably the mulcher) used an edger and chopped off ALL the grass in many places like 1/2 an inch away from the edge of the walk and left nothing but dirt and it just looks kinda crappy now. I mean it looks like an edger has been there, but looked a lot better the way I was doing it. My question is "Should I get an edger"?
