Hate to tell you but piss doesn't keep deer away from your plants. I live in the boondocks & piss off my deck more than inside. I have a bird feeder right off my deck & the deer come every night to eat seed that has dropped to the ground. Also when they pump septic tanks around here they spread it on farmers fields for fertilizer & it doesn't faze the deer. Deer will eat the whole plant, rabbits chew the stalks off, raccoons do nothing & nothing will touch them once they start to bud... except thieves & cops.
