How to stop rabbits from eating my hostas.

The rabbits eat only my solid green hostas. They eat the leaves first. Then the stems down to the ground. I don't have deer, I only have rabbits, squirrels & chip munks. What can I put on them to stop the critters.

Doug says 1) build a fence, 2) spray with plantskydd, or liquid fence. While not supposed to be for rabbits, these products do seem to work on them.
