Growing Aster (Aster)

Pronunciation: ass'ter 

Grow in full sun (or partial shade in the South) in moist but well-drained soil (A. amellus'Violet Queen' tolerates drought). A. novae-angliae 'Alma Potschke' and 'Purple Dome' are susceptible to powdery mildew in dry soil. They also require division every year or two to remain vigorous. A. 'Alma Potschke' may require staking; if you prefer, you can pinch it back once or twice (by ⅓ - ½) before the end of June (July in the South and the Southwest) to keep it compact. In the South, A. X frikartii 'Monch' may stop blooming by midsummer; shear it back by half, and it will bloom again through the better part of fall.
