I have about 12 well established(~15 feet tall) willow trees growing in the middle of my pond. They stand in 3-5 feet of water. How do I kill them? I am trying to avoid any cutting because whatever I cut will have to be done from the boat then loaded on the boat and taken to shore. I was hoping for an easier solution than this. Can I drill holes in some of the branches and pour herbicide in?
