Stop in for a cup of coffee

It does grow back. I will cut a 4in round Buckthorn and a year later there are shoots growing from base. Supposed to put some poison on stump but can’t afford to treat over 32 acres
Gardener friend of mine said whenever he has to remove a tree, saw it off, drill a 1" hole in the stump, fill the hole with pool acid. let it sit a couple weeks, stump comes out easy. bigger stumps need more holes and acid. must eat the roots from inside out.
