It might be worth sprinkling the plants with cayenne pepper. You might
even be able to mix it with water and spray it on. I know I use it to
keep the squirrels out of my bird feeders. (Birds have no "sensors" for
capsacin.) It works wonderfully, too much so to make my husband happy
because he doesn't get to play with his pellet gun.
