When to plant Plant in spring or fall, but avoid summer because astilbe doesn't like to dry out. Soil Use a loose, well-draining, soft soil mix that can keep the seeds moist but not wet. Sowing Press 10?12 seeds into the soil's surface without covering them. Astilbe seeds need light to germinate. Germination Place the container in a warm, bright window with a clear plastic wrap loosely on top to retain moisture. Mist the soil and seeds daily through the wrap, and remove it once sprouts appear. Astilbe seeds typically germinate in 28?35 days.
