We are currently under construction, and will need a small 'wall' area to one deep end corner of our pool. We initially thought we could just leave it graded off, but it's looking too high so we'd like to add a wall of some sort. I love the look of natural boulders, but I can't quite picture the top part where the wall would meet the concrete decking along the pool. Boulders with mulch sounds ideal to me, but dyed mulch (I hate the natural stuff) only being 3' away from water with kids and dogs doesn't sound like a good idea to me. I also thought about adding a shorter section of decorative fence and having a climbing perennial there instead. Any other design tricks I'm missing? I'm in overload mode and my brain has shut down from being in the middle of a build.
