I have had a lovely mauve wisteria for about 10 years and noticed exactly the same thing happening. At first I put it down to the very heavy rain knocking the leaves off but it just hasn't stopped and now the branches are looking bare. I will see if there is a mushroomy smell as I didn't know about that. It is very curious that it is happening to so many people.
I planted two wisteria plants this spring.They were both doing great until a month ago when one started turning yellow and now it is dying.They are about twenty feet apart.The other one is fine.Any ideas what I can do ?
I planted a new wisteria in the spring it has flowered and now, this last week the leaves have gone brown and fallen off, I don't know what to do. I live in France and the weather has been really hot could this be the problem? There is no sign of bugs.
I have a very old 20ft high wisteria spread across the front of our house. In the last few weeks it is turning from green to yellow to almost white. It was producing new growth up until then. Has anyone heard of any new from the RHS on this subject?
I've had a healthy wisteria for about 6 years. The flowers were a bit smaller than usual this year but it now appears to be completely dead: all the leaves have shrivelled up and died.
I can only add to the depressing list of wisteria news by reporting that my 8/9 year old Wisteria started turning yellow a few weeks ago. Most of the leaves have now fallen off and I fear the worst. It had only begun to flower in the last couple of years so I am most upset. As it's been an unusually wet july/August in England, could it be waterlogging? I think there's different problems here. Some peoples W's are turning Brown and shrivelled (eg Amanda in France) whereas my leaves went yellow, then fell off.
Our wisteria was planted in a sunny spot and trained to grow up the outside wall of the house about 11 years ago. It has successfully grown without trouble. In the spring 2009 it produced its flowers in abundance followed by the leaves. The leaves started to wilt around June. The whole of the shrub is now completely dead. No local environmental changes. We would appreciate some advice.
It sounds like we need to look for common themes here. On another site, I read something about Wisteria's turning yellow if they do not have adequate drainage. Since this summer has been cooler and wetter than most in a long, long time, I wonder if this is the reason? In circumstances where one plant is doing fine and the other failing, are the failing plants in a wetter location (at least at the root level)?
Sadly our nine year old Wisteria has also succumb, the leaves started to turn yellow bit by bit after typically vigorous growth up until late June. It now only has a sprinkling of pale dying leaves left and the garden looks more like Autumn with dried leaves blowing all over. I do wonder about waterlogged roots in July as this is when it really went downhill ... here's to next spring!!
Yes Jon, we do need to find a common theme. I take back what I said about two different kinds of symptoms. My leaves have gone yellow and fallen off and now brown and crispy and falling off... and all over the garden like Iian's. The plant has really taken a downturn this weekend (but it hasn't rained for a while) and I think is dead. The plant is in a dry spot but my soil is clay so the roots might well have been waterlogged through this summer. Is anyone's dead wisteria in free draining sandy soil?
