May have been short of water if you have been away? Difficult to say with out a photo, do you have one?

I will take a photo tomorrow. We had loads of rain while I was away so not sure about that one.

Draughts not likely be the problem then. A photo may well help.

Daniel Deronda is in a group of clematis which are particularly prone to wilt - it may be that it happened whilst you were away, and all you're now seeing are the dead leaves/stems. If its finished flowering, and all the stems are in the same state, with shrivelled leaves, cut it down. Alternatively, just cut down the shrivelled parts, leaving anything still healthy.

Thanks Bamboo. I just put some pics on .I've just had a good look at it but can only see 1 place that has a tiny bit of new growth. Should I cut it back to ground level ?

One thing comes to mind could these just be broken stems rather than anything else? I would cut it right down and give it a nice mulch. Somehow I think it will be ok.

Thanks, will do..
