What to do if your astilbes lose colour

Recently I answered a similar question on astilbe flower colour. It is important to remember that astilbe by nature is a water hog, so moisture must be consistent throughout the growing season. Astilbe actually works well as a waterside planting for ponds. Make sure your soil has good moisture retention capacity with lots of organic matter. Or grow your plants close to a water tap!
