Question

A 11 year old wisteria leaves turning brown and droping off?

Answer 1

Try watering with sequestered iron,diluted as the packet instructions.This is often caused by a mineral deficency.

Answer 2

I would check the trunk of the wisteria if you can as well because I had one trained up a pole which was stunning and the same thing happened to me. It was a borer which eventually killed the plant. I didnt see the hole until it was too late.If there is a hole with or without sawdust around it, straighten out a paper clip and poke all around in hole. This should kill the borer.  

Answer 3

No.
