Astilbes plants - root division
I've several astilbes in large containers that appear to have "outgrown" their space. Can I divide astilbes? If yes, what is the best way / time of year?
Thanks for writing. You can divide astilbes like you would any other perennial. They're not particularly fussy about timing --- do it anytime from spring to fall.
