Fence it in

I chose to define the space with split rail fencing. It is simple and informal and appropriate for the site. The split rail is for aesthetics only as it won't keep rabbits or squirrels from entering the garden and munching on the tender greens. For that I'll have to add small mesh wire fencing along the inside perimeter of the rails. So far, we've put up two sides, the other two will come later this spring when the ground thaws. We found some perfectly good old rails that were being thrown away so we only had to purchase the posts.
