One of my rhodos on the ocean side was damaged last winter as the salt water reached it during a big storm. There were still flowers on the ends of the outside branches and a few leaves but the branches are now woody all the way back to the base on that one side. This is an old shrub but it has had lots of flowers in the past. My question is should I now cut off those woody looking branches? Now that the flowers on these branches are finished there does not look like much is happening. I cannot see any green shoots anywhere on these branches.
