Can you post a photo or describe the chewing? Is it holes in the leaves or are the leaves completely eaten off the plant and it just has petioles (leaf stems) left?

Holes is probably slug damage (or hail). You can get slug bait at any garden center.

If the leaves are completely gone then I would guess deer. Liquid Fence is going to be your friend, or build a really tall fence around your gardens to try to keep those hooved devils out.

If the leaves are chewed almost off, but some leaf is there and some have nibbles stems here and there I would suggest either rabbits or woodchucks. I think liquid fence will work for them too - or dried blood or milorganite.

Post a photo if you can (or a better description) and we will try to help.
