All of the beds from both houses have natural edges, except that one surrounded by concrete. A nice cleaned up edge will do wonders. It will give it a sharp crisp transition to the turf. Square shovel would work. Or a bed redefiner attachment if you happen to have either stihl or echos kombi set ups.Which one looks like natural edge? And no, I'm not sure if I know how to recut the edge and clean it up. Square shovel?
