Rabbits Are Ruining My Garden!
It doesn't take long before the rabbits will become comfortable with your tactics, so you've got to try lots of different things in rotation. You can try whirligigs and wind-powered wood tappers. The scent of human hair and predator urine (fox urine, specifically) will scare them off. Blood meal is a deterrent, but it is pretty much pure nitrogen and you've got to be careful not to get it on your plants. Still, it offers good short-term protection until your plants are up and beyond the tender tasty morsel stage.
