50 Blue Aster Flower Seeds

Blue Aster Flower Seeds - Bloom Flowers Spring Perennial Wildflower

Asters need little in the way of maintenance. Care of asters may include deadheading for more blooms and occasionally includes controlling powdery mildew. This disease is most easily prevented by the autumn or spring division of aster flowers, with the middle clump removed and discarded.

Plan on starting the Aster seeds indoors 6 - 8 weeks before the end of the frost season. The flower seeds should be gently pressed into the soil and covered lightly. Keep the Aster seeds moist until germination occurs. Transplant the young Aster plants into the garden in full sun to a partial shade location.
