Wisteria and Russian Vine problem

Almost a Halloween tale now I come to think off it. A month or two back one of our Wisterias that grows up the side of the house shut up shop for the winter. A bit early I thought. And then there was something wrong with the leaves. They didn't go brown and drop off, but just curled up, still green, on the plant - as if someone had cut through the stem (which they hadn't).

Yesterday I was hacking back the Russian vine that grows along the hedge - is the hedge in some parts. That two was exhibiting the same ostensible signs of drought, leaves curling up and dying while still green.

Only certain areas (unfortunately the majority) are affected. Elsewhere the plant is growing normally at it's usual mile a minute, and still flowering.

Anyone know what is happening here? Is this normal, or is there a virus in my garden. And if so what other plants may it affect? The other wisteria is behaving normally with leaves just now turning a colourful yellow. But the first looks winter dead, though I suspect the stem is still alive.

Toady's Avatar You'll probably get the definitive answer from Milla or Withy but in spite of all the rain this year it can still be very dry near walls and at the base of hedges and that together with the drying winds we've had this autumn may be the cause.

Fennie's Avatar Thanks, Toady. It certainly looks like drought - but we've had so much rain!

Lampworkbeader's Avatar It sounds like honey fungus. That causes sudden unexplained die back. Have you had any other deciduous shrubs die recently?

Salle de Bain's Avatar We have 2 wisteria growing up the front of the house. Last year one died off early, whilst the other kept going. Don't know what the problem sounds a bit like yours, but I must say that the affected plant came back with more vigour than ever this year......very strange. I do find that mine are affected by wind too. The plant that faces the windy side never thrives as well......

Westerwitch's Avatar Wow and I thought Russian Vine was virtually indestructible. I used to have one when I lived down South - I miss it . . . Hope you find out what is wrong Fennie . . .

Did the leaves have any powdery type stuff on them? If so could be powdery mildew which I have found quite common on a variety of plants that grow up walls.

Fennie's Avatar No, no powdery stuff. Just exactly the sort of wilt that you'd expect to find if the stem had been chopped through

Withy Brook's Avatar Fraid Withy is failing you this time. Sounds abit drought-like. Hard to believe!

Elizabethm's Avatar Not at all sure. Doesn't sound as though it can be drought. I would assume some sort of virus, cut off the affected parts and burn them and cross my fingers for next year.

Camilla's Avatar Hello Fennie,

My HL hacked my Wisteria down to nothing a cople of years ago, eek.! after it took almost 7 years to establish in the first place. Did not think it would grow again but last year it flourished again although none of those gorgeous blue/purple bunches of flowers yet, sob............ I was hoping that it flowered this year, sadly not. There is an abundance of leaves, but they do look a tad brownish, stems are alive though.

We planted the Russian Vine (mile a minute) when we purchased the cottage years ago, heck..... it grows like mad, I usually have to cut it right back at the end of flowering quite severely.

Fennie's Avatar Thanks everyone for your ideas. I'll let you know what happens.

Arosebyanyothername's Avatar I diagnose wind damage.
