Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Ice out, What is this?

Manual removal will work just fine for the dead stuff if it's Eurasian Water Milfoil, but not for the viable, growing plants. They spread by seed AND via cuttings, so you could spread them quicker.

It will take over a pond quickly, growing in water that's over 5' deep to the surface if the water has enough visibility. I hate the stuff and never want to see it in my pond. Diquat works well for killing the stuff, but if you have a bunch growing, don't treat more than 1/4 of the pond at a time, you might cause a D.O. crash when it all starts to decompose at the same time.

Were there weeds growing up to the surface in the pond last year before ice-on?
