Too late to split Hemerocallis?
My 3yr old group of Stella de Oro has suddenly exploded in growth and is now crowding out other stuff. It’s begun to grow scapes. I think it may be too late to dig it up and split but if I chopped chunks off it would it harm the remainder? I can pot up the chopped chunks and they will either make it or not, but don’t want to kill the mother!
