This Lilly has been in my garden for years, but since last year it’s looking kinda sad. Is it sick, and can I save it?

I’ve taken part of the Lilly away because it was getting way too big, but it already looked like this when I did so.

It’s an outdoor plant, going through Western European summers and winters. So plenty of sun. I water it regularly when it gets too dry.
