wisteria erradication

Question

Problem wisteria which I have cut to virtual ground level. Choking up my sewer pipes and storm water. Have some blackberry/lantana poison which I have been told to spray on the ‘flesh’ of the remainder of the trunk. Would it be more prudent to get a stump grinder in and grind as deep as possible in preference to poisoning for months after grinding? Would the roots still survive under concrete (driveway) and cause further problems?

Answer 1

Some of the roots will continue to sprout even once the stump is removed. This article will help with eliminating wisteria: https://www.gardeningknowhow.com/ornamental/vines/wisteria/controlling-or-getting-rid-of-wisteria.htm
