I planted a Wisteria about a year ago and want to train it over an arbor. The plant is about 6 ft from an underground sewer line. Will this cause me problems? The plant above ground is so aggressive that it has me concerned. It seems to do very well in our dirt and climate.

Wisteria roots are aggressive and fast growing and can cause damage to foundations.
I would advise you move the plant.
