Wisteria Is Dying

Question

My wisteria is about 10 years old and is beautiful every year but this year. We noticed early in the spring that is was not as full as it used to be. It has been dropping leaves and is very sparce. New leaves are also dropping. We have had a lot of rain this spring and are wondering if that has anything to do with it. We checked the bark and no insects that we can see. Any suggestions?

Answer 1

It could be a fungus or it could be something affecting the roots. Treat the plant with a fungicide to treat for possible fungus. Next, check the roots for damage. Wisteria is susceptible to crown gall, so look especially for growths on the trunk at the base.
