Thank You!!! Water depth is 9 ft at its deepest, and we do have a lot of them.....pretty much totally covered during the summer...pond is more like a bog during that time. I have read about the Flourodone type products so will research them further for sure...any advise on the application time? I seem to find conflicting info on this particular subject as far as waiting until they have all surfaced and are in bloom verses applying as they crop up in the spring...
