MaintenanceBe careful when cutting these back in the fall or weeding around in the spring, they are easy to pull out of the ground. Some will jump around the garden by reseeding. Division of the clumps every 2-3 years will help to maintain the vigor of the plant. Astilbe are heavy feeders and need to be fertilized every year in the spring and also in the early fall. Some of my Astilbe tend to heave in the winter. In the spring I cover the exposed roots with soil, mulch or dug them in.
Author's NotesThis is one of my favorite Astilbe. It is very hardy, large, and blooms later. Have used this planting in many shaded garden plantings over the years.
