Ultra low budget deer deterrent
Attaching a medium sized
piece of tin to a post near your garden can function as a deer
deterrent if you've got enough wind where you live.
The above configuration gives
off a nice metalic sound as it flaps back and forth.
I wouldn't want to rely on
this method due to the obvious problem of no movement if there is no
wind, but it could function as an adequate back up to a motorized
deterrent.
