Yes. Placing a layer of topsoil or loose soil in the area that you want to grow lilies will help them spread and colonize the area faster. I recommend the loose layer of soil be 6"-10" deep. Typically lily roots (rhizomes) are several inches to 6" inches or more below the surface of the pond bottom.
