Instead of cutting a bed edge at 90 degrees to the grass, cut it at a 45 degree slope and go down 6". This leaves enough room for 2" of bark mulch, which will not mix with the grass but will be held in place by the bed edge. You can also stand right on the edge and it will never collapse. When mowing, you can lay the the lawn mower over the edge and cut all the grass, thus eliminating the need for a grass trimmer.
