My gardens are all behind fencing too. My raised beds are in my backyard and my other in ground plot near my chicken coop is behind plastic orange fencing on T posts.

We have deer, rabbit coons and such to worry about too but my worst enemy is the chickens!

Now, the garden I am sharing with my neighbor that is very large has a two strand wire fence around it...if you just glance at it you would think electric fence but it is not hot. There are a few pieces of plastic flagging around in a few spots along the wire and it seems to work well at keeping most critters out.

Like you, we don't mind sharing a bit. Good luck!
