Last year for some reason, we had an over abundance of rabbits in our neighborhood. I guess when there are alot of bunnies there isn't enough bunny food to go around. They ate everything- even the stuff that is supposed to be rabbit/deer resistant. I've tried everything I could to prevent them from eating my plants. I've tried moth balls, human hair clippings, coating with cayenne pepper and even all the sprays that were supposed to contain wolf urine, blood, etc. Truth is, when a rabbit is hungry it will eat anything. I only have about a 1/2 acre yard and on any given night I could open up my back door and see 8-10 rabbits looking at me. It was ridiculous. Best bet I think would be to do a combination of what a few of the other guys did, get that fencing stuff to wrap around your plants. I would also consider getting some clover seeds (rabbits LOVE clover) and planting it away from your vines to attract them to a different area. You can buy clover seed sold specifically for attracting rabbits on amazon.com for around $15 for a few pounds. Rabbit hunters sometimes plant clover in areas that they want to attract rabbits so they can shoot them! Good luck!
