Hi. I moved into a house with two rose bushes about 8yrs ago. Both were doing wonderful. Id prune them back in the winter and feed them rose food inthe spring. Sometimes i would have to trim them so they didnt impede the walkway. This year one of my rose bushes was stunted. It never bloomed and only managed to have a small amount of new growth (see photos). Im not sure what type of bush it is just that it produced large white roses. Is this bush dead? Im not sure what to do to help it. Food did not. I live in CA. I think my zone is 9b.
