I have a mulberry under my deck. It's really getting out of control.
I chop it off every year, but I know that's just a Band-Aid.

Last year I cut it off, drilled deep holes in the stump, and dumped in
Roundup concentrate. Didn't even skip a beat. It's bigger and badder
than ever.

I sympathize. Darn things seem to have more lives than a cat, don't they?

I did manage to kill one, once. I cut it off as close to the ground as I
could, and poured a LOT of salt on the freshly-cut surface. I repeated the
application of salt several times over the next week or so -- every time the
cut edge looked wet, I poured more salt on. Tree died, and (surprisingly for a
mulberry) it has *stayed* dead.
