It is the first time that I have grown Canterbury bells. first year produced only leaves. This year I have enjoyed a vast array of colour; however, they have now finished. I wondered whether I should deadhead as they have thick stems. Also, when should I expect my next blooms?
Kind regards, Steph

Yes, deadheading is always a good thing, and you may even want to save some of the spent flower heads for seeds next season. Here is more information: https://www.gardeningknowhow.com/ornamental/flowers/canterbury-bells/canterbury-bells-plant-how-to-grow-canterbury-bells.htm
