I am so sad to say that I think I may have lost a most beautiful rhodo this year. We got an unusual amount of snow this year and my neighbor ran out of room to pile his snow so he used my rhodo bed (despite the burlap barrier) to pile the snow off his walkway. I believe it must have had salt in the snow because the rhodo just is brown and not a sign of life to it. However, when sratching the stems, there appears to be green underneath. Is there any way to resurect my rhodo or should I just replace it?
