I know this is not stictly a climber but I am growing it as one. It is about a year and a half since I bought it and recently I moved it to a sunnier position (previously it was in a shady part of the garden and did not produce many flowers in the winter). Unfortunately a week or two after I moved it the leaves started turning brown and now the whole thing looks very brown and sad. The stems are still green but they are brown in places. Is it likely to survive or shall I accept my mistake and buy another one to replace it?
