Astilbes are long-living perennials that are most comfortable when grown in rich soil and light shade to filtered sun. Though they are easy to grow, astilbes have one critical requirement–lots of water. Plants must have consistently moist soil; dryness leads to a quick demise, especially in the sun. Increase watering as the foliage emerges and the plumes mature. If the soil dries out, the leaves will develop brown, crispy edges and begin to fall off. Add fertilizer in the late spring, before flowering starts. Cut back the old foliage in the spring, before blooming begins. In the spring, if the crown has risen above soil level, gently press it back into the ground and apply some organic matter around the plant. Astilbe plants should be divided in every 3-4 years to maintain vigor.
