Q.Rebuilding old wisteria pagoda
I moved into a new house last year with an amazing wisteria pagoda. It’s built on concrete, as previous owner was wheelchair bound. I am replacing with lawn that will be a higher level so I need to rebuild pagoda. There are two trucks that are over 12 inches in diameter. Can I chop back, rebuild and regrow?
This is an unusual situation.
It is most likely that with time the Wisteria would recover, as it is very difficult to 'kill' Wisteria vines.
Adding soil to the base of the plant can cause disease or fungus and this can severely compromise the plant.
This is the most questionable part of the project.
You may want to take some cuttings from you vine to use to help regain the plant base when you are finished with the landscape project.
Here are some links with more information.
