Campanula flowers are dying off???
I bought seven Campanula plants last month and they have been planted in the ground as a boarder. I have noticed that the flowers on three of them have started to shrivel up and they look a bit drab. I am no 'Green fingers' and would love some help.I have no over watered them and they are located in sun/partial shade. Am I correct in thinking these type of plant should flower all summer?
Thank you in advance.
