So we are going to be ordering the river rock and garden boulders on Saturday (3/5) for delivery 3/11 for our pond - but I am trying to figure out how to get plants among the rocks surrounding the pond. I'm thinking of buying some of the clay pots (medium sized probably) and putting those down first, then stacking the rocks around them to sort of hide them. I want to plant things like creeping phlox and such to help soften the rock barrier around the pond. Any thoughts?
