Now getting rid of true morning glory that has gone feral is a different story.
One thing that might work is a method I used to get rid of Canadian Thistle that was spreading like wild fire.
I dug down to the root, did not pull the plant and painted it with systemic weed killer.
Within two years it was gone.
