Asters perform best in rich, evenly moist soil and full sun. Give them lots of room to grow; good air circulation will help to prevent powdery mildew. Though this cultivar has a bushy, compact habit, it may still require staking. To promote dense growth that is less likely to flop, pinch plants back from late spring until July 4th.
Plants should be divided every couple of years in the spring to maintain their health and vigor.
