I put wood chips around some wild roses - they're in a wee bed in the lawn but without a 'physical' border - it's just bed then the dug edge then grass.
Anyway, something keeps ferreting around and digging out all the wood chips and sprinkling them over the lawn - we thought it was hedgehogs snuffling about, but it's being going on over the winter too, so it's probably birds rooting for stuff.
It's a fascinating story, I know, *takes bow* but the point I'm getting to in a slow and roundabout way is if you want a tidy edge between chips/lawn then put a wooden barrier or something down. I haven't, but then am happy enough to just keep sweeping them back in.
There. I've said it.
