Thank you. They don't like salt, you will see some damage if they get directly hit by it constantly. I have used them in partial shade areas, I have seen growth slow but they have not dropped many needles, again PARTIAL shade. I have never had a Norway fall over on me and even after Sandy only the largest of the Norways fell. 60' maybeee BUT unlike white pines guys seem to use a Norway won't thin out its foliage (unless in shade), it maintains a tighter shape, it tends to drop less needle (less acidic content into soil) and final as it grows you will never loose branches at the base of tree, so privacy will always be there. here's another...these are 12-14' we used believe it or not.
