Get rid of small silver maples along fence line and around pool area

Well, I spent a lot of time looking for solutions, and came up with a few suggestions. 1 - herbicides that are recommended for woody plants (Triclopyr or Picloram as the active ingredient) are the ones that work. They take a while to work, though. The chemical should be applied to a freshly cut stump so it absorbs into the root. This is best done in the fall. I am going to do it until the damn things are gone. 2 - Dig it out. These are frequently runners from another tree. Killing these roots with chemicals may harm the tree. In my case, there is no tree to worry about. 3 - Be persistent. It takes a while, and they grow fast and furious.
