I need some dahlia advice - one of my plants has been wilting and noticed that some of the leaves have brown patches appearing. Had a look over it and cant see any bugs and popped it out of the pot and no bugs in there either. Its kept in a greenhouse over night and out side in the day. I thought it was maybe full sun making it wilt but I have put it in a bit of shade and it still wilts, so I don't thinks its happy. Does anyone know what might be causing it and what the cure might be?
