Hi I recently bought a property with a giant rhododendron grove (for lack of a better word) and this winter it has suffered badly. I have several areas which have brown leaves that are pointing down :( I am not sure what to do to best help it recover (if it will). I have had people tell me to prune it and others to water it and let it drop its leaves and regrow new ones ... all in all the grove is about 50ft long, 15-20 feet wide and probably 10 - 15 ft tall at its highest point. We sprayed it in the winter to protect if from the hungry deer. Please help .... it is a big old bush and I feel bad for it. Nancy
