I see that you are from Massachusetts. This past winter was quite cold in the Northeast and that poor rosebush could be a victim of it. All my
rose bushes have leaves on them by now. I had to cut quite a lot of dead stuff this
spring so the cold did affect them too. I always cut my
rose bushes back in the
spring. That is what my mom taught me to do. If the whole
rose bush is dried out then it is probably dead. However, try cutting some of the dead stuff and see if there is still some life in it. If there is, it might just be a late starter.
