I'm no pond management expert, but I would be careful about putting anything other than maybe cattail in a pond. Cattail gives bait some cover near the bank. Although I have seen ponds completely fill up with cattail too but I think its because of the natural sedimentation and build up of organic matter. Aqua vegetation will take a pond completely over and you would likely regret it. If you are throwing Fertilizer to it as well I would be very careful of Eutrophication. You could get an algae bloom and a mess on your hands. I'm assuming you want this for fish management? I would be happy I had a clean pond and go the artificial cover route to help the fish. My Dad just had to have 2 of his cleaned out last year due to vegetation and silt in. Killed all the fish I had raised in them and now one leaks. Be careful what you are asking for. Everyone else is fighting to keep vegetation out. Be interesting to see if any of the guys with more knowledge chime in.
