I've had it with the cattails in my warmwater pond. I erradicated them once before and when I turned my back voila they're back in full force. My brother-in-law and I are having a -ell of a time removing them from my .62 acre pond but we will prevail! My weed cutter and weed rake are getting one heck of a work out not to mention our arms.
From now on they will get zapped with herbicide whent hey start poking out of the water next spring. No if, and, or buts!
Word of warning to those of you who don't know. There is NO just a few cattails just like they is no such thing as just a little bit pregnant! They will try and conquer your pond if you let them! NO MORE!
