Can Astilbe Get Too Old

Question

I know they’re perennials, but mine aren’t doing well even in spring. Do I need to replace them?

Answer 1

Their vigor will depend, very heavily, on their environment. They tend to be a little picky.

The plant requires shade, and only light dappled sun. Too much sun will scorch them.

They should not be allowed to dry out, fully. They are not tolerant of dry soils.
