Planting/Care Instructions +

Pests or Diseases: No serious insect or disease problems. Deer-Resistant Good For Cutting.

Planting Instructions: May be planted in any well-drained soil. Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. Easily grown in average, medium, well-drained soils in part shade to full shade. Prefers moist, humusy, organically rich soils. Soils must not be allowed to dry out. If regularly watered, foliage will usually remain attractive throughout the growing season. A summer compost mulch helps retain soil moisture. Many gardeners leave the flower stalks in place after bloom because of the continuing ornamental interest of the dried seed heads. Astilbes are mainstays of shade and woodland gardens.
