Forget the human hair myth. I have been there - done that & it does not work. Actually kind of grossed me out touching other people's hair! Even with the gloves that I was wearing. I have tried just about everything and the best options that I have found are deer fencing and deer spray. Unfortunately both are on the expensive side though. The deer fencing is a light, thin black mesh fencing that comes in 6' x 100' pieces (about $18 each). This fencing is great for wrapping around the trees to prevent them from rubbing the trunks, but unless you cover the entire plant, or what the deer can reach, it will not stop them from eating the plant; and yes, they will eat the sapplings to the ground! The other option is a deer spray. I have tried numerous companies / products and the best that I found is Deerbusters. It comes in a 5 gal concentrate and I forget the price and total gallons it makes, but if you are really interested, let me know & I will get it for you. The deerbusters actually lasts the 30 days as it advertises. All of the other brands that I have used do not last more than a week, with some of them not even lasting hours. No kidding. I have sprayed some plants and literally a few hours later, I witnessed deer eating the very plants that I sprayed! That is my 2 cents!
