If the leaves are still on it, spray it with Roundup. Takes a few days to
see results, but it won't survive and it won't come back because Roundup
kills all the way to the root. But if there's anything else under there
that you want to save, cover it before spraying with Roundup since that
stuff will kill anything. Grass, flowers, weeds, big trees even, if you had
enough of the stuff.
Read the labels and find one which applies to trees. While Roundup is a
great herbicide one which is lsited as a "brush killer" (Bayer make one
called just that - brush killer) is needed on something as tenacious as
Mulberry. A state forester instructed me that you can indeed paint the
stumps with it and, in most cases, it will work. A method which he
specifically preferred for cantankerous trees is called, 'slash and fill'.
Cut deep gashes around the trunk but do *not* let them connect. This
produces a bit of a resevoir which you fill with full-strength brush killer.
That's it. The tree pulls the stuff directly into its system and kills
roots and all. Will Bob M's method work? Probably will. No slight
intended to him. This is just another method for you to investigate.
