|my astilbes are healthy with lots of blooms, but the color lasts less than 2 weeks. Is there anything that will prolong the color?

|I'm afraid it's just the nature of the beast. Hot weather lessens the lifetime of the plumes and there's not much you can do to change the weather. Afternoon shade will help the plants maintain their plumes and the leaves a little longer in the season. Wish I had more to share. Best wishes with your landscape.
