Hmmm... I've been trying to think of an inconspicuios way to accomplish that, would the canopy of a tree not block the light needed for the plant(too shady). How good can a 5 gallon bucket be camo'd where it dont look odd. Maybe look into products made to repel animials, ultrasonic emitters or something. Or fencing off an area or putting up one of those large dog pens. Just a few ideas.
