Answer: Since this is not the norm for "Moonshine", I would suspect there is some sort of insect on the plant and the birds are after it rather than the plant itself. You might be able to tell after a very close inspection. To stop it, you will have to figure out what the insect is (if I am right) and then deal with that. However, you may find that a sharp spray with the hose or a good rain will stop the problem by knocking them off, or the insect population may drop eventually on its own due to the bird acitivity. You could also temporarily cut back or even cage the plants if you wish to protect them. Assuming the plants are not totally uprooted, they should be able to recover and rebloom later this season. How perplexing!
