Once established, asters will do well for years.

Asters are a cinch to grow. They will do well will in rich to average soils, but dislike permanently wet soil. The soil needs to be porous, though. Like all plants, they will reward you with bigger blooms and a healthier plant if you add plenty of compost. Also, add a general-purpose fertiliser once a month.

Sow seeds early in the season and cover lightly with soil. Water thoroughly once. They germinate easily and will grow quickly, producing blooms by midsummer.

Transplant perennial asters into an area where they can be grown for years. Spacing depends upon size, with miniature varieties spaced 30 cm to one metre apart, and giant varieties one to two metres apart.

Smaller varieties make good border edging. Large varieties look their best when placed in the back of the flower bed.

Once your asters are established, they will grow well for years.

Asters will withstand dry spells well. Once established, they will only need water during extended droughts.

Plants will begin to bloom in mid to late summer. You can expect continuous blooms up to frost. Remove dead flower blooms to improve plant appearance. For giant varieties, trim back any stalks, as desired, to maintain an attractive appearance.
