I'll run an edger the 1st time or 2 to get it in shape, Then maintain it with a trimmer. Like someone said earlier.... It really is an artform & takes some practice, but once you got it down it's faster. One tool, it's already in your hand & running. I make 1 trip around the homes with a trimmer & trim what needs to be trimmed & edge what needs to be edged, Then 1 trim around with a blower..... DONE & GONE! Never had any complaints at all. I do find the edge line will be a little wider with a trimmer (not 2 inches but wider than an edger line) but I find it grows so fast here for 6-7 months of the year that just using an edger looks good for only about 2 days (I won't be back for 7) the trimmer leaving a little wider gap keeps it in check til I return.
