Suzi, I would put JD(that's his name right?) to work building a cage for you. This year, it could be as simple as 3-4 poles or sections(tall enough to account for this years growth and your height) of metal conduit staked into the ground and some chicken wire wrapped around them, with a layer on top as well to stop the climbers and flyers. Attach the chicken wire to the poles with some steel wire as you wrap it around until it overlaps where you started by about a foot or so, don't attach the overlap to the last pole(which would also be the first pole where you started). To make a gate, just crimp the cut ends so they don't poke you, and fasten the overlap layer of chicken wire to the underneath first layer with something like a couple cheap alloy carabiners or similar. The very end of the overlap/gate piece could also be wrapped around and stapled to something like a section of 1x2" wood cut to near the height of the cage, this will give the end of the gate some rigidity and prevent it from being unweildy. Another point, when you buy chicken wire, it comes with thin wire wrapped around it to hold it together, this thin wire works great to attach layers of chicken wire together if the height isn't tall enough, just overlap top and bottom 4-5 inches and use that thin flixible wire to secure together.
Cheap carabiner key chains can be found for less than a dollar each.
