I'm hoping that the Tordon will take care of both the stump AND all of the roots. I know that it works best in the Fall when the tree is pulling its resources down into the roots. However we had temps in the 50s for several days in November and December when I was cutting down trees and more than once there would be sap running out of the cut, and the buds were swelling and almost ready to leaf out.

I agree that regular mowing helps control both tree root sprouts and new seedlings in a lawn. I'm a little concerned about mowing on the face of the dam because of the steepness. Will try it with a Ford 8N & 6' bush hog.

Also will be doing some spot spraying with 2,4-D. Poison ivy in places too.
