Hi All,
Not sure if this is a allotment or a flower mill question.
I got some Canna tubers very cheap this weekend and have some dahlias too and was planning on planting the Cannas and half of the Dahlias on my allotment and rest of Dahlias in pots in my garden. Do Cannas and Dahlias have to be lifted in winter. I live in Reading. Will it be ok if I cover the bed with black plastic to protect from the cold/frost? Are Cannas better grown in pots on on the ground?
