I'm planning to put a fence around mine to keep out birds, rabbits and the dogs themselves. They will still be able to get around all four sides of it to keep critters off the property. The only thing I haven't decided is whether to use utility panels or chicken wire for the fence. DH thought if we could use utility panels and attach them to each other at the corners, it would be a snap to take them down when it is time to retill next year. If I use chicken wire and t-posts, we will have to till around the t-posts. I can see his point but worry that the panels won't be stable enough just holding each other up like that. Then there is still a matter of figuring out how to put in a gate....I'm still trying to figure out how I can keep them out of it, but allow the dogs in to keep wild life from coming in.
