I have two water iris one is a yellow Louisiana (or so I was told) and the other is a beautiful purple one (see picture below). I need to divide them though, they are over taking my little pond! They were in pond pots but have burst out of them. So can someone tell me how to divide them please? I have never had much luck with water plants lol but these ones, well they are something else!

TIA!
