I've heard many of people give advice on the subject, yet no one has found a silver bullet. I have thought to change the PH temporarily until i can mulch & plant over it. Any luck with these efforts? I am considering the effectiveness of growing allelopathic plants in a perimeter around the worst area. Then Possibly using an extract from them to spray the vines directly? Thoughts?
I like the 'rip-it-out-by-the-roots' method. When I am pulling it out (with linesman's pliers and gloves), I try to lift the underground runners so I can preclude it popping up in another spot. I don't want to be playing whack-a-mole with this nasty plant. Since it can thread its way underground to new territory, I am doubtful that chemical changes on top, either in the way of pH or some allelopathic exudates will help much.
If there is a large area, I think you have to do some real damage to it, i.e., use modern agricultural technology: drag a disc over the area and till it all under. When it does pop up again (like it is doing in the road construction in front of my house where the graders went by a couple months ago), it will be more exposed and easier to find and yank out by the roots.
Then again, you could run some goats and pigs in the area, and they would make short work of anything growing in there.
