Q.Wisteria looks dead
What would make my wisteria look dead? It only has a few green leaves at the very top and it did not bloom at all this spring.
There may be a delay in your wisteria leafing out due to the weather, so it may just be dormant. In order to know if it's dormant or dead, you should check a stem for flexibility. If the plant bends easily, it’s ok. Dead plant stems will snap and break off. Also, conduct a scratch test. Scrape off a little bark - do you see green underneath? Green indicates health. Unfortunately, if it’s brown and dried out, the plant is most likely dead. For more information on the above information, please visit the following link:

If your wisteria is in fact dead, it may be due to a cold injury it sustained over the winter months.
