Wisteria Help please (pics)

[SorryNotSorry]

Hi
we have just moved into a house and inherited a container grown wisteria. The leaves look healthy enough but it is almost bent double.
Any tips on how we can fix/save it. We don't want to train it against the house as we are planning an extension and all other fences are swamped with ivy.
Thanks in advance

Poor thing! It looks healthy though. You can get a support with a sort of umbrella frame that they grow over. It would probably need a bigger pot though. Or it can grow over an arch?

I think I would re plant in the ground (after flowering is over) if you plant at an extreme angle it might counteract the existing angle.
It likes full sun and planted as deep as the roots and at least twice as wide.

Thanks for the advice I think it might need to go into the ground with roots diagonally and supported to fix the angle and also over a frame the umbrella one looks nice.
Probably best to wait until any building work is completed though so will do some supporting in the meantime.
Thanks again.
