I have a rogue tree growing under my deck.
I hack the branches off, but each year it comes back bigger.

Is there some way I can kill it, or do I have to tear up my dig and
dig it out?

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.
