Even though dahlias prefer warm climate they will die to the ground and the roots can be lifted from the ground and stored in cool, yet frost frost free conditions during the winter. Another way is to plant the tubers quite deep which also provides protection from frost. Some dahlia cultivars need staking for support. All garden dahlias need deadheading regularly.3
After a killing frost the roots may be carefully dug and stored through the winter.
