Very soon I'll start seeing Japanese beetles munching on my Frau Karl Druschki hybrid perpetual roses and Ostrich ferns. Strangely, they leave all my other plants and roses alone. I've had almost no success fighting them off with commercial or homemade preparations. Has anyone successfully repelled them and how?

There's really no way to repel them that I know of but planting 4 o clocks will attract them and kill them so if you have a good spot for them try them and see how they do. I'm doing that this year since they love all my roses and blackberry bushes.

You can also treat your lawn with a grub killer that will lessen the pressure in your yard. It won't keep some from coming into your yard but it can help.

Hang Japanese beetle bait bags on the outer edges of your property, it will draw them away from your garden and they will die inside the bags....toss in the trash when they are full.
I have used the Spectracide bag-a-bug bait traps for years with great success.

Around here they only attract more beetles than we would normally get. I've banned them from the yard here because I have more issues with the bugs with the bags hanging than when they aren't. Last year I cut off the blooms of my roses and between them and my blackberries I just plucked the ones left into a bucket of soapy water.

Now at my grandma's place on the other hand, it won't matter if she has the bags or not they're horrible!! Last year I was picking peaches from trees that were loaded with the beetles. I had them dropping into my hair. I got a small crop picked for her from one tree but we were too late for the other tree. The majority of the peaches got eaten by the beetles.
