Eating my campanula glomerata superba

Question from SunshineNat

Something has been chewing the leaves down to the stems, removing all the leaves rather than leaving bites. There are no trails (slug/snails), organic slug pellets have made no difference and they do not seem diseased. Is it possible deer have been munching?

My Campanula Glomerata Suberba all appear to be dead

Question from angela

I planted some Campanulas this summer and was really disappointed to find after a few weeks of hot weather they all shrivelled up. However there are still a few little flowers left, right at the bottom of the plants.Can any advise me on what to do next please as am new to gardening and have read I should cut them back? If so, by how much?
