Aspen prefer light soils that are acidic and drain well, but these conditions are rarely found in urban areas. Aspen will do best on the north and east sides of buildings. If the soil where an aspen tree is to be planted has a high content of clay, build a berm of sandy loam 18 to 24 inches high. A berm is a mound or wall of earth. The berm should be mulched and several plants should be planted in the bed. Please see the PlantTalk script "Aspen trees" for more information.
