We recently moved house in New Jersey and I'm finally getting around to getting the back garden into some kind of shape. There are trees along the perimeter of the property which i assume were planted for privacy. I think they are fir or pine trees. There are no no needles on the lower branches and the upper branches look pretty sparse. The bark looks very pale and is peeling. I'm hoping someone can tell me what is wrong with these trees, and whether they can be saved or is it better to have them removed.
