Wisteria vine thickness

Hello, I've recently acquired a garden with a neglected wisteria growing up the back wall of the building, I'm a little concerned as there are several vines growing around/behind some of the plumbing - I'd like to know how thick the stems are likely to get as I don't want it to break the soil pipe!

Thanks, Rich

    Over the years, wisteria stems can get very thick at the base end.   If you're really worried, just cut those vines at the base and leave the ones that are not likely to cause damage.   After a few weeks, the cut branches will have wilted and be easier to pull and cut out without damaging the rest of the plant.

    Train the remaining branches as horizontally as possible and away from gutters and pipes.  There's some really good info on the RHS website about how and when to prune wisteria to maximise flowering.
