Answer: Dahlias go through a natural dormancy period and need this winter rest in order to produce foliage and flowers each summer. The plants won't adapt to growing indoors, so I can only suggest you enjoy the flowers in your garden until frost nips the foliage. Then dig the tubers, store in a cool, dark place, and wait for new buds to develop in the spring. Once the buds begin to show, plant the tubers outdoors again.
