OK, there aren't a lot of people around here who edge flower beds and the like, or at least I've never spent a lot of time in the neighborhoods where they do, so I'm going to ask a dumb question. I was wanting to re-mulch around our trees this winter, and thought edging around the edge of the mulch would help eliminate grass growth and trimming. I saw a post about the TrenchRblade, and bought one. I also checked out the TrenchRblade website, and watched the video of one in use. The operator used the blade, then pulled the mulch over the cut to the grass line. This makes a nice, neat looking edge, but wouldn't the problem with grass growing into the edge of the mulch still exist? How do you guys do it? Do you actually leave a strip of bare soil between the edge of the mulch and the turf or not? Thanks, cause I'm !
