Hopefully someone can give me some advice. I have 5 dwarf Rhodi's that were planted 12 years ago and they have always done well with no care other than winter mulching. This spring they produced no leaves but produced 1 or 2 blooms per plant. Quite frankly the plants look quite dead, but since they did bloom I am hoping to save them. I live in south central Indiana and the winter was not bad. Any suggestions would be much appreciated. Thanks.
