I have chimney bellflowers in my garden bed which are a first for me, they have been magnificent but i'm not sure how to manage them for the autumn/winter? Do i cut them back or wait for them to decay? The reached about four/five feet tall. Many thanks.

Campanula pyramidalis (Chimney Bellflower) is a short lived perennial. Some of the members grow this so hopefully you will get a more detailed answer?
