Best Perennial Asters (page 3 of 3)

How to Grow Asters

Spring is the favored planting time in all regions. Most species grow best with full sun and well-drained, fertile soil.

To minimize mildew, provide good air circulation by spacing plants liberally. Interplant with spring-flowering bulbs such as daffodils, or with wildflowers, to fill gaps early in the season before the asters fill out.

To promote dense, compact growth and eliminate the need to stake, pinch back growth tips two or three inches once or twice in spring and early summer before flowers begin to develop. Or shear asters back by half in spring.

The fastest-growing asters require yearly division in spring. Others need dividing every three years or so. After lifting and dividing, replant sections from outside the clump and discard the old center. Propagate by division or by stem cuttings in spring or early summer.
