I've never had any trouble with cutrine killing any grass around my pond that was in direct contact with the water, so I don't believe it will harm higher plant species. I'm not sure if it will effect germination of seeds though. FA is pretty bad at my place right now and will probably still be too cold(<60deg)to make an application for another month. Maybe your seeds will germinate by then?
