Campanula care one flowers fade
What should I do with Campanulas now the flowers are fading? I have always found this site helpful, and have a query about Campanulas. I'm afraid I don't know the species, but they are the type commonly sold in supermarkets (the purple flowering, low growing variety described by Tesco as "purple bellflower Campanula sarastro). I have been growing them for several months but now many of the flowers have died, and I am left with purely foliage. Should I trim this down, or let it die back naturally? I understand the plant is a perennial, but can I do anything to help it, or conversely should I avoid any particular course of action for fear of harming it? Thanks.
You can deadhead the spent blooms. Here is more information: https://www.gardeningknowhow.com/ornamental/flowers/campanula/growing-campanula-bellflowers.htm
