Usually when placing river rock or other graves in the landscape we use a heavy gauge filter cloth to prevent weed growth. This cloth is usually wrapped up neatly allow the edge of the soil to contain erosion. As with most of these conditions, these measures can help prevent weed growth but most likely, over time, will not stop it all together. Some maintenance would be required.
