A root problem with Wisteria

Tricky one to answer, I suspect a lot depends on what sort of 'footings' the wall is built on. I have a friend who has an enormous one against the wall of an outhouse with no problems. However your wall sounds a bit small. It may be a good idea to keep it in check.

Thanks for that, it's my cousins problem realy. I was praising the GoY freindship. Then he popped that Q. to me I said I didn't know, but I know someone that will .I will tell him in the morning. Frank

By the way Heron he was a builder before he became ill. So I think the wall will have been done right.

Only comment I'd make is 7 inches is too close for the health of the plant, never mind the health of the wall! Should be a foot away minimum, really, but never mind now, if its been in 2 years. I don't believe the roots will cause a problem with the wall if, as Heron says, the footings are good, or there are, in fact, footings - really old walls don't have them at all, often.

The 7inches is from the short wall 1ft high but 7ft from any other wall. The wisteria is trained up and over some trellising and onto a pergola. It does look quite effective. Frank

It sounds beautiful Frank, We all like Wisteria but not all of us can have one as they need lots of attention and space.
