To me, no tree is more beautiful than a white pine, and the screening they make is awesome. I loved the looks of them so much that I planted several years ago. However, I quickly found out that they were not without problems on my place:
* First, if you plant the small ones like the state nursery sells and don't protect them, the deer will eat them to the ground. I was able to get around this a little by making a hole in a briery place and keeping the top open enough for the tree to grow. The briers would sometimes provide a degree of protection for a while, but you had to be sure and keep the top above the tree open.
* Second, once they get like 5 feet tall, the bucks on my place started targeting them for rubbing. They were like magnets and seemed to be preferred over any other tree. It's just not realistic to try to cage them due to how wide they get at the bottom, and it's not just the small ones that they hit. I've had several to make it to 6 inches DBH (and probably 12 feet wide at the bottom) only to get hit hard by a buck.
* Third, for some reason I have been seeing mature white pines dying at a lot of different places in the state when I am traveling. I probably have about 75 on my place that made it, but I have two or three to just up and die each year. I'm talking about trees that are now 20 to 40 feet tall. In researching this, I found the following link put out by the University of KY. It goes into some detail about three different diseases that kill the trees.

I have come to the realization that for me, thick shrubs are my best solution for screening. However, that won't work for Ben, because of the height he needs. Norway Spruce doesn't seem to be bothered by diseases (yet), but they are slower growing than white pines, and deer will rub them too.
