No way in hell I would drench this fine body of water with 2, 4-D. No way. I'd also go Jenson Lake Mower. Lilies are the easiest in the world to cut, and only a few mows will deplete those rhizomes. In this day and age I'd say 90% of my customers flat out state no chemicals, no herbicides and no poisons. I go mechanical almost every job I do now. And I also endorse Annamarie and Jenson as a fine company and stand up people as far as business people to deal with. The Lake Mower makes my job very easy.
