May 12, 2014Q.Wisteria Diseases
My 30-year-old Wisteria sinensis has died! Last year about a third of it died and I cut it away. It was very dark on the inside of the sawcut. This year the remainder started to grow but very slowly compared with other wisterias in my garden, then the growth stopped and died back. It is now completely dead looking and my intention is to cut it all down. What I would like to know is why it has died. It is on the south side of my house and completely covers the south- and east-facing walls. I have a 2-year-old layered plant from this, about 18 inches from the main root. Will this be okay, as it looks very healthy. Also, will it be neccessary to completely dig up the old root?

Certified ExpertA.There are a few root diseases that can do this, like cotton root rot or crown gall. I would dig up the root to see the condition of it. This will give you a better idea of what exactly the root disease that killed it was. The nearby plant may be in danger. I would keep a close eye on it and treat the area with a fungicide, which will help kill some of the possible causes of the older wisteria's death.

October 29, 2014Q.Wisteria Carbuncle Problem
We have a number of ten year old Chinese purple wisteria, some of which are experiencing a clumpy growth on the stems. These growths may be as much as 6 inches in diameter, are brown and clumpy. I see none anywhere near the root area, so do not believe this is classic crown gall. Also, other than these unsightly growths, there is no real damage to the plants; no leaf dying, flower problems, or anything. What might it be?

November 3, 2014A.There are several cankers and galls which can affect wisteria. Probably you should have the clumpiness examined by a professional, either at a nearby nursery or at the extension service. This link will help you locate the nearest one of those:
