Dahlias - to cut back or not? Im a gardener, and just been to one of my clients. Her dahlias have all finished flowering now and are about 5ft long and straggly, as they do this time of year. So I decided to cut them all back. Now I know the old school would have you pull them up to be put in a sandbox but ive found they always come back year after year so i leave them in. Anyway she has a friend that comes every so often and also does a bit of work in her garden as he doesnt have one. He turned up today as i was worked and told my client that her dahlias would now die as they shouldnt be cut back until febuary to protect them from the frost. Just wondered what some of you folks views on this are?
