The back lawn at the house we bought last year has a wavy edge that migrates a bit and isn't very neat. I don't mind the natural look too much, and tend to think lawn edging is a bit naff, but lately the natural curve has been looking a bit wonky - possibly because our predecessors had it professionally maintained but we don't - and so I'm starting to waver a bit. I'd appreciate some views on whether edging would give us a permanent solution or just be another thing that needs to be maintained (whilst perhaps also looking a bit naff).
