Ivy plants do not need soil to live or grow. In the 1990s, there was a trend that had people putting betta fish in vases, and topping the container with a soil-less ivy plant, with the roots placed directly in the water to provide oxygen for the fish and water for the plant. There are also gel "soil substitute" products such as "Crystal Soil," in which ivy plants grow and thrive.
