I love a rock garden with wet look rocks. The glossy look is so pretty and much more inviting than dusty old rocks. I placed the rocks under the bow windows about five years ago. The rocks were buried by dirt over the years. I wanted non-plant material under the bow windows so we wouldn’t have to have grass there that needed watering. The problem was that the sprinklers would get the bow windows wet and they were becoming damaged by the water. So, my solution was to remove the grass with the dirty rocks and install a rock garden, so we would not need sprinklers there.
