About Aster Flower Bulbs
Aster Flower Bulbs grow in full sun positions. Expect 12 to 24 inches at maturity. Flowering runs late summer through fall. The figures below are the ones on the packets in this group; each product page carries the exact numbers for that variety.
When to plant
Plant in spring. Bulbs go in while the soil is still workable, and want to be in the ground long enough to settle before it freezes. Hardy in zones 3 to 8 — your local frost dates decide the exact week.
Where to plant
Choose a site in full sun. Water needs are average once the plants are established. Drainage matters more than anything else: bulbs sitting in wet winter soil rot. Allow 24 to 36 inches between plants so air can move between them. Plan for 12 to 24 inches of growth when you place them in a bed or border.
How to plant
Set the bulb deep enough to accomadate root length deep, pointed end up, spaced 24 to 36 inches apart. Water gently to settle the soil, then keep the surface evenly moist until seedlings or shoots appear.
How to care
Keep watering average, at the base of the plant rather than over the leaves. In zones 3 to 8 these come back each year: let the foliage die down naturally after flowering, since that is what feeds next season's growth. Flowers appear late summer through fall; cutting or deadheading regularly keeps more coming.
