I haven't tested this idea because all of my vulnerable plants are fenced. Yesterday, at the nursery, I was told to put salt licks that you buy at the feed store every 100 feet around your garden area and the deer will go for the salt and not your plants. Maybe.
Personally, I don't want to put out anything that will attract deer to my property, so I'll leave it up to someone else to test this idea.
Last year, during the third year of our drought, my neighbor above me didn't water his large lawn area where what I consider his private deer herd foraged. They all came down to my small patch of lawn, which is really more of a cover crop for the roots of my maple tree. They ate every single deer resistant plant I had out in deer territory and I didn't have to cut the grass all season.
btw ... roses are deer candy. They are one of the best ways to invite deer to your garden. Mine are fenced.
Smiles,
Lyn
