Can Miniature roses be grown outdoors in Summer and then be brought indoors for Winter?
Yes. They may be lifted from the garden in late Fall or early Winter after they have been dormant for a month to 6 weeks. Carefully pot them in a large pot and with well-prepared soil. Water them thoroughly and gradually subject them to the warm indoor temperatures rather than bringing them from the cold out-of-doors to the warm indoors. Then follow the indoor culture.
