Answer: I'm sorry about the deer. The fertilizer they gave you may have been Milorganite, this will sometimes repel them by its odor but many deer become accustomed to it and browse happily away. It also needs to be reapplied after every rain, and will not help in the winter time. Also, although it is a slow acting form of nutrients, you would not want to be fertilizing nonstop. The best thing you can do is to fence the deer away, either out of your yard or away from each tree. You might have luck using a cylinder of wire mesh wide and tall enough that they can't reach the branches over it. (I am thinking of large meshed relatively inexpensive barnyward wire sold in a roll at the hardware or lumber or home center store, about four to five feet in height minimum for the cylinder.) This will also protect the tree bark from them rubbing their antlers on it. Alternatively you could use one of the spray on repellents formulated for deer (sold at garden centers), most people have better results when they alternate between different brands so the deer do not become accustomed to the odor. Your trees may leaf still re-leaf this season, or they may not. I would be very patient and see how they do next spring, I think they are probably okay. In the meantime, do what you can to stop the damage. Keep in mind deer will eat or trample a wide variety of plants so this is going to be an ongoing problem since they are already in your yard and in the habit of eating there. Good luck!
