wisteria
By Phillybilly

I have a 7 or so year old wisteria which flowered well this year. However, about four weeks ago it suddenly wilted and lost all its leaves. I cut back some of the wispy bits and then tideid the plant up. Now it seems to be spring again (in September) and is has produced lots of flower buds. By the way before the wilt it produced a number of seed pods. Any ideas as to what is happening.

With all the rain we had it seemed unlilkely but that was my impression. The new growth produced over the past two weeks is encouraging (I did give it a good soaking) Will have to wait till spring to really know but your comment is encouraging - Thanks. Will continue to do the normal regime of two prunings (September and February) is not too cold.

Hope this answer isn't too late.
Odd as it may seem your Wisteria may have dried out, if it is against the house with roots under paving, or there may be ants nesting around the roots.
Dust around the roots now with Nipon, water in after a day or two. Cut off the seed pods, you may have another flush of flowers soon.
Wait until March and prune as normal.
