water hyacinths… care tips?

water hyacinths… care tips?

Can anyone point me to a site that explains how to care for water hyacinths? We added a couple to our fish pond earlier this year and I'd like more info on how to take care of them. I know they grow like weeds, and I can't toss the extras anywhere near water. What I want to know is how and when to split them, can I trim the roots, etc... to keep my pond looking nice :-) Thanks!!!
