Thank you for the question. We had a hard winter and many of us are discovering perennials that didn't make it through. Roses are no exception. Some hardy and the more wild-type roses die back to the ground each year and put up new growth from their own roots the following season. If this is the type of rose you have, then there is no problem. Other roses are grafted on to a hardy root stock that can usually survive our harsh winters if prepared for winter properly. If this graft is killed, the rose that grows the next season from below the ground and from the root stock and will most likely, be nothing like the rose that was grafted on to it. If this is the case, you will need to dig the plant up and start over with a new one. Please read our publication on growing hardy roses:
If you have some of the more tender rose bushes, winter care is recommended to protect the graft. In fact, most roses, even the hardy ones benefit from some winter protection. Read more here:
