Paul, I am so sorry.
I never had any luck with the repellents. However, that may be because I am dealing with what I call "town deer". They were born and raised in town and were taught by their mamas to feed in people's gardens. They are used to all of the repellents and think of them as normal. They don't even know that a bobcat is a predator ...
Last winter the deer found a way into my garden and deer chomped my roses horribly. Even when I finally found where they were getting in and blocked that entry point, they were making blind jumps over the deer fence that used to keep them out. I finally had to make that fence even higher this spring to save the garden.
Once the deer know where to find their deer candy, they seem to be more persistent than we can imagine.
Good luck finding a solution. The photos of your roses are breathtaking.
