I wanted to throw in my no frills for Frillylily fencing. Say that 5 times fast.
My husband and I planted a large veggie garden behind our church. We took leftover rebar from building our house and spaced them out around the garden. Then we strung white string between the posts, and had aluminum pie plates dangling from more string. Probably 2-3 plates between each post. The theory being the deer couldn't see the string and would run into it causing the pie plates to rattle. We didn't use urine, Irish Spring soap, human hair, or any other kind of deterrent. The only damage to the garden was from pilfering low class human critters.
