Have you tried cayenne pepper?

You might want to post this in the Plant Clinic (aka Pest and Diseases) forum....this is the Insect Forum. ;-)

Go to your local nursery and ask them for the liquid products they sell. They usually are made of pepper, rotten eggs, and other disgusting ingredients that keep the rabbits off. I used one of these products on my garden and it worked.

Wanna borrow my dog? :o)

I've got a life size cardboard cut out of Elmer Fudd that you can borrow. :)

my dog made a huge difference in the bunny problem. Didn't get a chance to experience my hostas until this year (3 Years later), cause the bunnies would always feast on them. This I allowed my dog to pee in the front yard (where the hostas are),et voila!!! Hostas and no bunnies!!! Good luck!!! Borrow a dog!
