Wisteria is beautiful but, can be very invasive and be a nuisance. Spray with glyphosate (roundup). Since the wisteria covers such a large area, you will need to spray several times. Just make sure you read the label and follow the directions. You can also try cutting down the trucks and spraying the stump with the glyphosate. Don't get discouraged if it doesn't kill it after the first application. Just keep reapply as often as the label tells you until you see results. Hope this helps!
