I have exactly the same problem, I have had my Wisteria in a sunny spot for a few years and it always grows well although I have neglected to prune. I have been waiting for it to flower since it was first planted 5 years perhaps., it has started its growth well at first this year and is full of flowers for the first time since I first got it. before the leaves or flowers have opened properly it has all gone yellow and looks very unhappy. what can I do I am so dissapointed, who can help us?
