I need to edge my lawn to create a separate space for flower beds. There are threads about plastic edging, but I wonder if I can just use standard 2" x 6" Cedar planks for this.
Any ideas on whether this makes sense or how to do it?
Sure. Cedar planks make a good looking edging. The only problem you'll have is providing for curves. I've handled this by making cuts on-half way through the boards one quarter of an inch apart. This seems to allow the planks to bend in gentle curves that suit flower beds.
