I planted 5 of my 7 potted roses in the spring. The other 2 sat on my deck all summer. The ones that I planted are doing great and are still in bloom. I live in Maryland and we've had a light frost. The 2 roses (1 double red Knockout and 1 Sea Foam) don't look too good, though they still have some green leaves and a couple of buds. Is it safe to plant them or should I bring them inside my home for the winter?
