You can use sections of gutter guard around new plants to protect plants from hungry rabbits.
Provided you bury it deep enough so they can't dig under it, plastic mesh like this works well as a rabbit deterrent.

I’ve had success using gutter guard plastic mesh to protect my plants from hungry rabbits.
Simply cut the desired length of gutter guard, form a circle with it, and secure with twist ties. Place the circle over the new transplant and push firmly down into the soil.
