Answer: The first thing to know if deer, if hungry enough, will eat anything! Rhododendron aren't their preferred food, but they can browse it. If they're eating your rhododendrons, then anything you put there will get eaten. Try caging the plant during the low food times for deer (late winter) or spraying repellents such as Ropel or Hinder to drive them away. It's a matter of experimentation.
