You can get a list from the local garden centre, or from the internet, of plants that deer don't like.
Don't believe it- they eat almost anything.
Even in the middle of winter the deer are coming into the gadren- we see their droppings in the morning. Any shoot that dares stick its head avove ground ricks being nibbled to death.
I've found a great book here that I'd love for my birthday next month- anyone looking?
