Can Beijing Canna spend the winter outdoors?

Can't! Canna likes warmth and plenty of sunshine, and is not cold-resistant. It requires deep and fertile soil, and potted plants require loose soil and good drainage. Fertilization is usually carried out during the growing season. In the north, underground tubers should be dug out before frost and stored in an environment with a temperature of about 5℃. Frost will wither flowers and leaves.
