Once campanula has flowered, should I cut them low to promote new growth? I have now enjoyed them for two months, but they are 'finished blooming.' I had cut them last fall. They are in a container on terrace, will be very exposed to sun. Many thanks.

Campanula can be deadheaded to encourage additional blooming, as most will continue blooming throughout June. If you've already been doing this and it's simply done flowering, go ahead and cut the plant back to encourage its new growth, along with a second wave of fall flowering.
