Last spring I installed a simple rock border around my house. It's about three inches deep and goes out three feet from the house. I used long strips of doublelayered weedblock, and I pinioned some cheap plastic edging along the perimeter. I then filled it with bags upon bags of river rock. Problem is, that plastic edging didn't hold up real well through the winter, and now I have to consider how to redo it. Any ideas? One of my mistakes was to join the separate pieces of edging together with plastic joiners, which was messy. Should I skip this and just overlap the pieces together and bend them around corners? Also, if you recommend that plastic edging route, how should I secure the edging in place?
