Chop 'em back if you don't mind the look. Liriope is very hard to
kill.I thin mine out with a heavy metal rake and rip them up by the
roots to get the dead off. It comes back green and happy.

Do you know anything about pond building? the Pond chat group is
talking about Jesus or something. (I don't recall Jesus having a pond,
so I think maybe their conversation is pretty worthless to me).
