My poor astilbes

My poor astilbes

Does anyone have any growing or care tips for astilbes? Some I bought as babies, some I started from bulbs. I have three together in the backyard, and they seem to be doing a little better. However, I get none of the colorful foliage that you see in pictures. Mostly the leaves look like they're drying out. I've followed all sorts of tips I've found online. They are planted in well draining soil with plenty of organic matter, and I water them often and keep them in a fairly shaded area. When I go jogging or for walks, I've noticed other people seem to be having the same problems. I've only seen one garden in town with really nice full astilbes. I went and knocked on the door to see if she would share a few tips but no one was home. They're gorgeous plants, I just can't figure out what's wrong with them.
