I had posted this last year when I tried it, and it works. It's a simple bag fence, using white plastic bags from the stores. Little electric fence posts will work. just put a stout string around the perimeter about 30-36" from the ground. Tie plastic bags on it every 3-5 feet. (poke holes in bottom so it don't fill with rain.) Colored bags don't work well. I protected a half acre of Austrian winter peas last year this way and normally the deer would pull them out by the roots as soon as they sprout. The bags must give off a glow at night and with the movement, is just enough to keep them at bay. The cost is mighty cheap, just the posts and some stout string, the bags come free with your purchases. Wind will cause them to bunch up, so you need to check them often. Got the idea from an old timer who uses them to keep deer out of his truck patch. He used nothing but white bags, too. Try it, you'll like it.
