newly planted astilbe
I planted three bare root astilbe last spring in a prepared, soil tested, shaded bed. They seemed to struggle. I just raked the bed today & I see no sign of them. Is it still too early? I live in zone 6b - northeast Ohio. Thanks! Debbi Faight
It is still a bit early for leaves to be emerging in 6b, particularly in shady spots. A chilly March isn't helping! Plants respond to soil temperature, not ambient temp. However, the crown of astilbe is often very near the surface. Raking with a metal rake might even break off tender leaves. Many perennials show little above ground growth their first season; they are focused on root development. I expect you'll see growth in the next 2-3 weeks.
