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.


Roundup doesn't work that way. It is a systemic killer that needs to be
absorbed via the leaves.

You could drill a bunch of holes again and fill with a high nitrogen
fertilizer or manure and cover with dirt. That will make it start to
decompose. I also remember buying a commercial product that was packed
in a milk carton style package that is used the same way.
